      Description

      Zinsser Watertite is a solvent-based, mould and mildew-proof, internal and external waterproofing paint that is guaranteed to keep water out by sealing masonry, and to give a fantastic finish in commercial spaces and workplaces. In-part, Watertite is designed for dank and damp cellars/basements, containing a biocide that protects the dried coating against fungal degradation for a minimum of 5 years. For ease of use and versatility, it can easily be applied to wet or dry surfaces in a range of light, pastel shades, to create a smooth, non-gritty finish.

      Watertite has a unique solvent-based formula that combines a state-of-the-art waterproofing resin with Portland cement to create a coating that stops up to 34psi of water pressure. It is ideal for rooms and surfaces where mould, damp and fungal degradation have been a problem; wine cellars; storage rooms in compartmentalised basement spaces; areas with minimal or poor ventilation.

      Unlike other waterproof coatings, Zinsser Watertite waterproofing paint can be applied directly to dry, damp or wet surfaces, allowing for water problems to be cured immediately with minimal preparation or surface drying-out requirements. It can also be recoated in just four hours, drying to a smooth, bright white, and non-yellowing finish that resists dirt and dust pick-up.

      Project and facility managers will benefit from using Zinsser Watertite in college, schools and educational facilities, where there are many storage rooms without ventilation, poor air circulation, and long-term requirements of storing paperwork, stationary and equipment on permanent shelving and units.

      Watertite can be tinted to most off-white or pastel colours, and has an ultra-low odour formula – lower than most standard emulsions. It adheres to any interior or exterior masonry surface, above and below grade, and is formulated to prevent recurring efflorescence on concrete and brickwork.

      Touch-dry in one hour and recoatable after 4 hours, surfaces must be free of any active leaks prior to the first coating. It is advised to apply Watertite to textured surfaces, and smooth surfaces may need to be abraded or blasted first, to create a surface profile. For more information about applying Zinsser Watertite, please refer to the manufacturer’s product datasheets, or alternately contact Rawlins Paints’ technical support team.

      questions Marty G on 2024-02-05 12:03:33
      Question: 

      My front door leads directly into my lounge. The exterior wall at right angles to the door has a damp patch, which appears to be coming from the exterior wall next to the door. This wall is painted, but the paint is peeling. I understand this paint should be used on bare brick, but I can't remove the paint. Will this work or should I use something else?

      Answer from Rawlins’ Technical Team: 

      Zinsser Watertite works best when applied to bare masonry surfaces, we would recommend removing the old paint prior to application.


      If the existing paint/plaster cannot be removed back down to a bare substrate such as brickwork, blockwork or concrete we would recommend Coo-Var Anti-Damp Paint.

      questions Emma on 2023-11-20 10:58:58
      Question: 

      Hi, The first 500mm of our external wall is below street level. We are seeing slow but consistent damp and acknowledge there will need to be regular maintenance as we cant feasibility stop the source of the damp. We are looking to strip the existing plaster to bare brick but only to approx 1m high. I understand this product is a 2 layer system, but would it be possible to add further layers this product for it to meet the depth of the existing (undamp) plaster and sanded back give a smoother almost invisible join?

      Answer from Rawlins’ Technical Team: 

      Unfortunately no, this product should only have a maximum of 2 coats applied to a bare prepared substrate for the system to work.

      If the product is applied only to a certain height, this will cause the system to fail as moisture getting in behind the coating will spread and form where the ridge will be at 1m high.

      Question: 

      I have had a door replaced with breeze blocks in my garage but rainwater seeps through the area - would this paint be suitable to waterproof the breeze block area please?

      Answer from Rawlins’ Technical Team: 

      While this product can hold back 34psi of pressure when applied to bare compatible substrate, due to the porosity of breeze blocks this may not solve the issue.

      Please can you provide more information and pictures of the internal and external areas in question to [email protected] so we can assist.

      Question: 

      On the exterior surface of an exterior brick wall the two coarses of bricks below the damp proof layer are badly affected by efflorescence and are very unsightly. I plan to use efflorescence remover then treat with fungicide . I would then like to paint these two brick coarses. Could you please advise as to which is the best paint for this use

      Answer from Rawlins’ Technical Team: 

      For application to clean, dry, sound brickwork below a damp proof membrane we would recommend to use a bitumen based paint such as Tor Non-Tainting Bitumen Solution

      questions Geoff Mizen on 2023-09-03 20:14:37
      Question: 

      On an external wall the two rows of bricks under the damp proof coarse are very unsightly .Covered in efflorescence .I am going to apply efflorescence remover but am wondering if I can then paint Zinsser Watertite on afterwards to make this area look better

      Answer from Rawlins’ Technical Team: 

      Yes assuming the brick wall is bare, clean, dry and sound this can be applied.

      Question: 

      Can I paint Zinsser Watertite over existing exterior masonry paint I want to be sure the paint on an exterior wall is the most water tight I can find and the wall is susceptible to algae. Existing paint looks in decent condo and not flaking.

      Answer from Rawlins’ Technical Team: 

      Unfortunately no, this product should only be applied to a bare substrate such as brick or block work.

      questions Jon on 2022-12-29 14:53:15
      Question: 

      Hi Rawlins Team, We have a smallish room which smells of damp, although there are no signs of actual wetness. We want a product to paint the concrete floor which can be overlaid with an underlay then carpet. Would Zinsser Watertite do the job?Could it also be used to paint the walls which have been plastered and painted? We'd like to overpaint it afterwards. Many thanks for your help! Jon

      Answer from Rawlins’ Technical Team: 

      Unfortunately no, this product would not be suitable for application to a plastered wall or a concrete floor.

      Assuming the plastered walls are clean, sound and prepared as detailed in the technical data sheet we can recommend Coo-Var Anti-Damp Paint for this application.

      For the concrete floor assuming you are looking for a surface applied damp proof membrane, the floor is clean, dry, sound and prepared as detailed in the technical data sheet we can recommend N-Virol Superseal Plus Damp Proofing DPM Paint.

      questions Alison  on 2022-10-08 08:55:57
      Question: 

      Hi, We have a board burner in the living room and the bricks around it suffer badly with salts. I regularly treat the bricks with salt neutraliser. I've decided to paint the bricks around the burner and I've jumped the gun and bought the zinsser watertite paint but now I'm worried (feel rather sick actually) that it's not going to withstand the temperatures around the wood burner and the paint was very expensive! Please can you help me? The wall has a distance of just over a foot at the sides of the burner and and 5" at the back. I'm praying that you're going to tell me the paint will be ok since it cost me £100! Kind regards, Alison

      Answer from Rawlins’ Technical Team: 

      It has not been tested for this.

      It’s designed to handle moist and wet surfaces like retaining walls… rather than hot and dry.

      Therefore, it is impossible to say what will happen here.

      questions Adam on 2022-09-08 07:19:00
      Question: 

      Hi I have a damp basement which I have tanked out but this hasnt really worked as the tanking has "blown" away from the wall despite using Sika Bond first. I was thinking of removing the tanking on the wall with the problem and replaing it with this Watertite paint. In the concrete floor I have used a 2 part epoxy paint which has been brilliant. What would you recommedn for the damp wall? Thanks

      Answer from Rawlins’ Technical Team: 

      Watertite can hold back upto 34psi of pressure when applied to a suitable substrate but it is not a tanking system.

      If you wish to use Watertite the failed tanking system should be removed first, but addressing the issue of the blown system and reapplying a Sika 1 Waterproofing System would be advised.

      Question: 

      Can I use this on plywood pleas? A section of my garage has been insulated & boarded out to be used as a pet grooming studio & the walls will be subjected a degree of water spray from shaking wet dogs & accidental shower spray, will this be suitable?

      Answer from Rawlins’ Technical Team: 

      This product is not suitable for use on plywood, assuming the timber is clean, dry, sound and prepared as detailed in the techncial data sheet we can recommend Teamac Metaclor Antifouling Primer followed by 2 coats of Teamac Chlorvar Chlorinated Rubber Paint.

      This can be mixed to many RAL and BS colours in a gloss finish, but this is not animal safe.

      Question: 

      An inner wall in my apartment is always damp bordering on wet, with the paint crumbling and bubbling. I suspect there is a leak from the kitchen pipes in one of the apartments in a higher floor which causes water to run down the shared walls, but even after a thorough investigation, I could not discover where the source is, as some people wouldn't let me in to check. I recently pealed the crumbling paint and rendered the wall, but i can't paint over the render with regular paint because it does not completely dry up. Can I use WaterTite on the render as paint that will stop the dampness?

      Answer from Rawlins’ Technical Team: 

      This product is designed to be applied to a bare substrate such as brick and we would not recommend it is applied to plaster or render.

      The cause of the leak must be addressed and the substrate allowed to dry prior to application of any paint.

      At this point assuming the wall is clean ,dry, sound and prepared as detailed in the techncial data sheet we can recommend Coo-Var Anti-Damp Paint.

      This contains an active reagent that will aid dealing with any remaining surface moisture, but this will only be a temporary solution and will ultimately fail unless the leak is found and repaired.

      It can also be overpainted for decorative purposes.

      questions Manish on 2021-09-17 19:48:11
      Question: 

      Hi, I had a front Porch built 5 years ago. Not sure what the root cause is, but every winter the inner walls collect a lot of condensation, even just touching the walls makes the hands wet. The porch is well ventilated all through the year via a small window that's always kept open but this doesn't resolve the condensation issue. I have fixed subsisdence cracks and repointed problem areas this year. will painting inside walls using Zinsser watertite paint help? I don't think I will be able to get rid of the existing paint fully. Should I use a Damp Seal Paint first/instead of this Product? Any advice would be much appreciated!

      Answer from Rawlins’ Technical Team: 

      Watertite is designed to aid dealing with moisture travelling through the walls when applied to a bare substrate.

      As you mention condensation you may want to consider Coo-Var Anti-Condensation Paint.

      questions Cameron  on 2021-07-20 11:45:34
      Question: 

      Does this product require any primer for a cement render?

      Answer from Rawlins’ Technical Team: 

      Assuming the bare cement render has cured for at least 30 days, the substrate is clean, sound and prepared as detailed in the technical data sheet it can be applied directly.

      Question: 

      hi I have used this in the past on internal cement rendered garage with no problems . We have just bought a new property that has white Efflorescence on the garage walls that is along the line just below ground level. No way of removing the external source so some external damp will come through periodically . Can it be used over the efflorescence deposits ? Thanks Jack

      Answer from Rawlins’ Technical Team: 

      No the efflorescence must be removed prior to application of Watertite.

      Question: 

      I have rising damp on my walls and my paint keeps on bubbling. I have fixed the dam issue and was wondering if I can use the zinsser watertite paint directly over the old paint or do I need to fully strip the old paint off the wall first?

      Answer from Rawlins’ Technical Team: 

      Zinsser Watertite works best when applied to bare masonry surfaces, we would recommend removing the old paint prior to application. 

      If the existing paint cannot be removed back down to a bare substrate such as brickwork, blockwork or concrete we would recommend Coo-Var Anti-Damp Paint.

      questions Barbara  on 2020-06-21 18:41:25
      Question: 

      A year ago we bought an old terraced house - built circa 1900. Roof repairs were carried out then, to stop water ingress and we think this has been successful. However, prior to that the wall (1st floor- alcove next to chimney) will have become very wet. Following the roof repairs we re- plastered and painted the area but crystals continue to come through. Should we strip back plaster and put on a new coat of plaster, followed by a treatment/paint (please suggest), or should we strip back and treat the wall before plastering etc. Thank you

      Answer from Rawlins’ Technical Team: 

      Assuming the source of the damp has been fixed, we can recommend Coo-Var Anti-Damp Paint as this is efflorescent resistant and should stop the crystals coming through the paint film.

      Question: 

      If I use Watertite on on an internal wall can I emulsion over it later to match the colour of the other walls in the room.

      Answer from Rawlins’ Technical Team: 

      Zinsser Watertite produces a beautiful, bright white eggshell finish. If desired, it may be topcoated with any quality paint, but will nullify the mould and mildew protection portion of the Zinsser warranty. To maintain the warranty, instead use Zinsser Perma-White Interior which can be tinted to nearly any colour and is available in a Matt or Satin finish. Allow a minimum of 14 days before painting.

      questions Martin on 2018-05-10 15:34:22
      Question: 

      I have the same problem as John with bleeding render. Do you have any other recommendations for exterior masonry paint to try hold this problem back? Also, If I use the Zinsser, which primer would be good to use with it please? Many thanks Martin

      Answer from Rawlins’ Technical Team: 

      The response provided to John (copied below for your reference) is our only offering for this issue.

      "Zinsser Cover Stain has been used in this situation to block the rust stains however there is no guarantee how long it will hold the stains back. As soon as any trace of moisture gets into the metal beading the rusting process will start again and stains are likely to bleed through once more. It would not be possible to say how long the primer would hold the staining back.

      Applying 2 coats of the Cover Stain will give a little more protection and hold back the staining for longer than 1 coat. The Cover Stain can be overcoated with a standard masonry type coating. Please note that the only 100% effective way to solve the problem would be to remove the affected angle beading and replace with new stainless steel or plastic beading."

      Question: 

      I have rust bleeding through the masonry coating on my house. The rust comes from the metal edging used by builders so I cannot simply get rid of the source of the problem. Can you recommend a product that will 'seal the surface' thus preventing further bleed. This product will need to be suitable for painting over in order to match the rest of the masonry. I have tried a number of sealants without success.

      questions Graham Peck on 2017-11-21 19:53:30
      Question: A below ground level (1m) internal wall in an old converted barn has been previously tanked, but now is damp. Plaster sound and render sounds solid. Will Watertite be a cost effective solution after stripping back plaster compared to very expensive re-tanking? Thanks for your help Graham
      Answer from Rawlins’ Technical Team: 

      Zinsser Watertite is a cheaper option than tanking and should work in this situation. It needs a sound masonry surface to bond to, all the plaster must be removed back to the masonry substrate. Apply the Watertite directly to the render surface, no primers or stabilisers should be applied. Be sure to read the products Technical Data Sheet carefully and advise if you have any other questions.

      Question: Hi,Can the zinsser-watertite paint be applied on internal skimmed walls. I have a house that is insulated and water has saurated the insulation and so in the kitchen water penetrates the wall and so paint flakes off.I note from the product description that it can only be applied on brick walls?Thankshttps://www.rawlinspaints.com/home/hygiene-coatings/mould-damp-proof-paints/447-zinsser-watertite.html
      Answer from Rawlins’ Technical Team: 

      Zinsser Watertite works best when applied to bare masonry surfaces, for your application you may be better looking at Rust-Oleum Mathys Durbocem or Coo-Var Anti-Damp Paint. The source of your water ingress should be remedied ASAP.

      Question: Is this the best paint to use in our cellar. Bricks are quite wet and in a couple of areas water is coming in through old mortar joints
      Answer from Rawlins’ Technical Team: 

      Zinsser Watertite should be OK for this job, this is the type of situation the product is used for. It can be applied to damp surfaces however these must be clean, sound and any previous paint coatings well adhered. Any gaps in the mortar joints where the water is leaking through will need to be patched up with render. Refer to the Technical Data Sheet and follow all the steps regarding preparation and application.

      Question: Can this paint be used over existing emulsion? I want to use it in the cellar, the plastered walls have already been painted. but damp is coming through in places. Provided any loose paint is scraped off, would this paint work?
      Answer from Rawlins’ Technical Team: 

      No, Zinsser Watertite should not be applied over existing coatings. Instead see Coo-Var Anti-Damp Paint.

      Question: Would it be ok in a bathroom to paint Watertight over water resistant plasterboard, and ceiling, then tile over part of the board?Is the paint likely to affect tile adhesion?
      Answer from Rawlins’ Technical Team: 

      This is a fairly common question and the answer is Zinsser Watertite is definitely not recommended for this situation. You should ask the supplier of the plasterboard if any special treatment is required before tiling over, but we would expect you can tile straight over the board.

      Question: 

      Can Zinsser Watertite be used indoors for damp proofing?

      Answer from Rawlins’ Technical Team: 

      Zinsser Watertite has a unique solvent based formula that combines a state-of-the-art waterproofing resin with Portland cement to create a coating that stops up to 34psi of water pressure. It can be used internally and externally on walls.

      questions Orpheus consultants on 2015-05-26 06:42:18
      Question: 

      Can we overpaint Zinsser Watertite?

      Answer from Rawlins’ Technical Team: 

      Zinsser Watertite can be mixed to most pastel shades and produces a smooth, eggshell finish. But, if desired, it may be over coated with most good quality paints, but this will nullify the mould and mildew protection portion of the Zinsser warranty. To maintain the warranty, use Zinsser Perma-White Interior or Zinsser Perma-White Exterior which can be mixed to almost any colour required in a variety of sheen levels. Whichever method is chosen, allow a minimum of 14 days before over-painting.
