trogers Posted July 29, 2009 Share Posted July 29, 2009 I do not understand the post. Is the question about waterproofing the bathroom floor to prevent leaks sideways and downwards, or is the question about prevent moisture coming up through the bathroom floor?

Crossy Posted July 29, 2009 Share Posted July 29, 2009 I think it's about preventing water penetrating the walls and affecting the next room. An issue I had in India, water from the shower room made the bedroom behind it damp and mouldy Link to comment Share on other sites More sharing options...
neverdie Posted July 29, 2009 Share Posted July 29, 2009 A common problem....back home they use a waterproofing substance, which is later tiled over, its some thick gooey substance, like resin with fibreglass strands in it, its called waterproofing from memory, doubt its used here in Thailand unless done so by one of the upmarket builders.

trogers Posted July 29, 2009 Share Posted July 29, 2009 I think it's about preventing water penetrating the walls and affecting the next room. An issue I had in India, water from the shower room made the bedroom behind it damp and mouldy These days, we use waterproof rendering (Brushcrete) on the bathing area walls before tiling. Common existing problem in many projects is at junction of wall and floor. In my projects, the contractor must first build up a 15cm high perimeter concrete curb before being allowed to build the block or brick walls. Waterproof is then installed on the floor to the side of the curb to tank the wet area. Link to comment Share on other sites More sharing options...

Common existing problem in many projects is at junction of wall and floor.

Yes, I use it on the floor and the wall. It is cement based and thus suitable for tiling. I think the product is now called Masterseal. Local agent is Thai Master Builder co., Ltd. http://www.arconsupplies.co.uk/pdfs/protec...rseal%20525.pdf Wall should first be plastered, and the floor screeded to slope towards the floor drain. When dry, apply Masterseal on to the floor and wall and allow to cure. Then water test the surface. When water tight, install tiles.

stgrhe Posted August 2, 2009 Author Share Posted August 2, 2009 Thanks Trogers, I will ask my builder to use the Masterseal 525 for my bathrooms. Is this product also suitable for swimming pools? Link to comment Share on other sites More sharing options...
trogers Posted August 2, 2009 Share Posted August 2, 2009 Thanks Trogers, I will ask my builder to use the Masterseal 525 for my bathrooms.Is this product also suitable for swimming pools? I would not use it for surfaces under water pressure. As swimming pools are usually constructed of reinforced concrete, I would recommend chemical treatment of the internal concrete surface. I have used Radcon successfully in elevated swimming pools of condos. Not only are the pools watertight, but also moisture-tight. No damp spots developed on the external surfaces of the pools. http://www.radcrete.com.au/Downloads/02-Ra...%20Brochure.pdf Local office is - http://search.yellowpages.co.th/en/profile...313938610130001 Link to comment Share on other sites More sharing options...
