Since 2018 it has been a requirement under British Standards BS5385-Part 1 that all wet areas – domestic and commercial – should be protected with an adequate tanking membrane prior to tiling.
A tanking system (waterproof coating) – such as BAL Waterproof 1C – should be installed onto backgrounds before tiling commences.
This is because tiles, adhesives and grouts themselves are not inherently waterproof and will allow water to pass through – potentially causing water damage, damp and foul odours to occur on the background or substrate.
BAL Waterproof 1C is a ready-mixed waterproof coating that can be applied easily with a brush or trowel in only one coat.
Crack-bridging up to 3mm, it is a fast-track solution, with tiling possible in 2 hours.
Priming isn’t needed on most substrates – including plasterboard. Where priming is needed – use BAL Primer 1C, quick drying one-coat primer.
Easy to apply straight out of the bucket, it provides coverage of up to 6m² – perfect for any domestic shower, bathroom or wetroom.
It also includes Fibre Strand Technology for improved strength.
