Preparation


Clear all areas of moss, lichen and debris by brushing or power washing and remove surface water and any contamination such as Oil or Grease and allow to dry. Apply Britannia Fungicidal Wash to prevent further fungal/algal growth.

Most roofing substrates to be treated will not normally require priming.

 

Highly porous/friable surfaces:

  • These Surfaces must be jet washed prior to applying the Britannia Aquashield Primer
  • Concrete, Concrete and Asbestos Cladding, Sheeting and Guttering should be primed with Britannia Aquashield Primer (see separate technical sheet) prior to over coating with Britannia Aquashield Waterproof Roof Coating
  • Fibrous cement corrugated sheeting: two coats of Aquashield Primer must always be applied to this substrate

 

Metal Surfaces:

Including:

  • Ferrous-new, weathered and previously painted galvanised iron and steel
  • Non-Ferrous Metals - Aluminium sheeting & Aluminium Alloy Box gutters and previously painted non-ferrous metals

All these areas should be suitably prepared and primed as appropriate (see separate technical sheet) before application of Britannia Aquashield Waterproof Roof Coating.

 

Non-porous substrates:

  • Slate, polished bricks should be power washed abraded and completely dry, free from any contamination to achieve adhesion of the Britannia Aquashield Waterproof Roof Coating

 

Bitumen surfaces:

  • Discolouration may occur over a new asphalt, tar or bitumen surfaces; therefore an extra coat may be required, for decorative purposes only. Aged bitumen can be liable to crack, therefore further advice must be taken

 

Previously painted or coated substrates:

  • It is good practice to inspect and carry out adhesion tests on any existing coating or substrate pior to application of the coating

 

Splits, cracks, joints and seals, crazed areas:

  • Pay particular attention to clean out any splits/cracks/joints and seals by scraping or brushing off with a stiff bristle brush before applying the Britannia Aquashield Primer. Repair all faults in the surface by using a proprietary filler.

 

Surface faults:

In areas where excessive movement may occur, additional reinforcement must be incorporated into the coating.



Application


  • To the dry and cleaned surface, apply a generous coat of Britannia Aquashield Waterproof Roof Coating by brush, squeegee
  • Please follow the Coverage rates shown in Spreading Rate Section
  • Apply between 5°C - 25°C
  • As dictated by normal good painting practice. In confined spaces, provide adequate ventilation during the application and drying



Cleaning


  • For all cleaning use white spirit



Shelf Life & Storage


  • Up to 2 years if stored correctly in an unopened container
  • Store in a safe place in accordance with the instructions in section 7 of the relevant MSDS sheet



Precautions


  • Flammable keep away from sources of ignition
  • Ensure good ventilation during application
  • Wear gloves, goggles and suitable protective clothing
  • Over occupied premises during insulation of coatings we would advise keeping windows closed
  • In case of contact with eyes rinse immediately with plenty of water and seek medical advice
  • Remove splashes from the skin with a recognised hand cleaner or plenty of soap and water
  • Keep out of reach of children
  • Do not use near fishponds
  • Harmful to aquatic organisms. May cause long term adverse effects in the aquatic environments
  • Do not empty into drains

Question: 

Hi. I have a bitumen flat roof, it is good condition, however last year I noted thin cracks where appearing along the joint lines and as it is in full sun all day and I wanted to prolong its life I painted it with your Blackfriar Solar reflective paint. Having checked it this year its evident the cracking is again evident and I now thinking the Britannia Aquashield High Build, in solar white, would have been a more suitable product? can I apply this over the Blackfriars?

Question: 

My lead clad bay window window flat roof approx 2.5m x1m has developed a small leak creating a disclouration on the ceiling below approx 10cm x 5 cm. Needless to say I cannot find the cause despite careful examination! The roof albeit old is generally in good condition. Rather than having a completely new lead roof I am considering painting with a waterproofing paint. Which - if any - of your products would you recommend? Many thanks for your help Regards Graham Pye Can you please

Answer: 

The Britannia Durashield system would be our recommendation for aged lead surfaces.

Question: 

I have a Garage that I erected myself about 2 years ago since then I have noting but problems with leaks. I tried all sorts of remedy's. My thinking is now to completely cover the whole roof with something. My garage is 17.7 sq mt Can you please advise me of a product that would do this your sincerely G Corns

Answer: 

You haven't said what your roof is - i.e. felt, metal, asbestos, etc. however if it is a substrate that Britannia Aquashield High Build can be applied to as per the product data sheet then this would be a good potential choice.

Question: 

Hello, I have a polycarbonate conservatory roof which has flash banding on some parts. Can I use your aqua shield solar paint on these materials assuming they are clean and dry? Thank you in advance for your assistance.

questions Ryan Russell on 2018-12-09 22:48:20
Question: 

I have a gutter between the 2 seperate pitched rooves of my house. Most is lead coated but the last and lowest 3 metres has been painted with something similar to your product but old and leaking slightly somewhere. Can I just clean, dry and paint over the leaky area with your product or will the old stuff need scraping off completely and starting again? Thanks.

Answer: 

Ideally we would recommend removing the existing coating to reveal the leaking area to enable you to prime, reinforce and coat the area as needed. If however this is not possible then as long as the existing coating is sound, well adhered and compatible then after cleaning Britannia Aquashield High Build could be applied directly.

Question: 

Hello, I have a workshop that has a corrugated metal roof some of which is in less than perfect condition, it would be difficult to remove and replace the roof and I am looking at alternative means of waterproofing it. Some of your products look as if they might be suitable, are you able to recommend any thing that might help. regards Michael Johns

Answer: 

After cleaning, assuming it is bare, weathered galvanised steel we would recommend first priming with Britannia One Pack Etch Primer before application of Britannia Aquashield High Build.
