Product Description

Product Use in the Workplace

  • Library - If there's any building that can have its contents ruined by a leaking roof, it has to be a library. Even a small leak can cause a big problem; if water collects in one particular area of the roof, it has the potential to cause the ceiling to collapse, bringing a whole pool of water down all over the books.
  • Factory - Industrial roofs are usually hard-wearing, but like all roofing, needs to be well-maintained. In addition to not falling down, a good roof is one that keeps the rain and moisture out of the building. Once water can get in through the roof, it has the potential to cause erosion on metalwork, increasing the chance of damp and mould. By ensuring factory roofs are adequately waterproofed, safety can be upheld and damage can be avoided.

Preparation & Application

Ready for use on flat roofs, pitched roofs, weathered asphalt and bituminous surfaces, gutters, concrete, brickwork, GRP and fibreglass, felt and metal (galvanised and ferrous). Fibrous cement corrugated sheeting: two coats of Aquashield Primer must always be applied to this substrate. 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. To the dry and cleaned surface, apply a generous coat of Britannia Aquashield Waterproof Roof Coating by brush or squeegee, at the minimum specified spreading rate as stated above under the heading. Application Temperature should be between 5°C-25°C.

Questions

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.

Answer: 

We would recommend Britannia Aquashield Eco for this application.

questions Ryan Russell on 09/12/2018
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.

questions Michael Johns on 06/12/2018
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.
