A waterproofing paint that is guaranteed to keep water out and contains a biocide that protects the dried coating against fungal degradation for a minimum of 5 years. This waterproof masonry paint can easily be applied to wet or dry surfaces creating a smooth, non-gritty finish.
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.

Hi there. Would this paint be suitable to paint the concrete floor of a shower area in our rugby club please? It needs to be anti slip too
No, we would instead recommend Smartkote Safekote.
|Justyn Phillips on 16/04/2019|| |
Hi Is this product ok to be used on a cellar floor & then covered in vinyl flooring? Kind regards Justyn
No, we would instead recommend our 402 Damp Proof Coating.

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.
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.

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
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."

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.

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
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? Thanks https://www.rawlinspaints.com/home/hygiene-coatings/mould-damp-proof-paints/447-zinsser-watertite.html
|Tracey on 03/09/2017|| |
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
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.
|Liz Spencer on 15/05/2017|| |
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?
No, Zinsser Watertite should not be applied over existing coatings. Instead see Coo-Var Anti-Damp Paint.
|Ali Reed on 23/04/2017|| |
Question: Can I use this product to paint over the tiles in my shower ??
No, you would need to use instead something like Rust-Oleum Tub & Tile Refinishing Kit.

Question: how many coats does zinzeer watertight require on bare block-work walls please
2 - 3 coats at 2m² per litre, per coat.
|G Overbury on 15/06/2016|| |
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?
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.

Can we overpaint Zinsser Watertite?
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.
