Dirk_brijs Posted April 18, 2015 Share Posted April 18, 2015 Looking for a 100% water proofing (epoxy) paint to make a concrete structure water proof. We will be using already a water proofed mixture but still need to put a layer (maybe a few) of water proofing paint. It would be used for a concrete aquarium feature actually. Looking for a pain t like "DRYLOK" but where is a paint like that available in Thailand? Thanks Link to comment Share on other sites More sharing options...
NeverSure Posted April 18, 2015 Share Posted April 18, 2015 Every Drylock product I know of is latex based. The best system I know of is to spray and then roll on hot tar and immediately apply and adhere a rubber membrane. The next best is cold soft tar and a membrane. Next best is just the asphalt product and next best is latex. Maybe there is an engineer here who knows better. Using a roller creates a pressure point that forces it into the pores. Even when sprayed on it is back rolled and spraying is just an application convenience. I've seen epoxy used as a wear surface such as on concrete flooring but I don't think it will waterproof if there's any later cracking. Link to comment Share on other sites More sharing options...

wonder6281 Posted April 18, 2015 Share Posted April 18, 2015 Just coated my Koi pond with 'Picture' .. Bought from a Hardware shop in Khao Noi but guess it can be bought elsewhere. If not we were going to use Shell Flintkote Super but it has been hard to come by this week. Link to comment Share on other sites More sharing options...
samuibruno Posted April 18, 2015 Share Posted April 18, 2015 make the same way as a swimming pool you can spray on new clean concrete a product like crystal lock /or radcon locks the cement molecules together [or something along those lines] then , tank the structure [render/plaster the structure with water proof plaster then water proof the wall/floor with your choice of waterproofing product fill with water and test before final finish if done correctly no leaks good luck Link to comment Share on other sites More sharing options...

fxe1200 Posted April 18, 2015 Share Posted April 18, 2015 I am a technical director of an industrial flooring company Sika is the product they have outlets here Sika should have something like the HVPO from Ispo Concretin, a two component resin with a specific weight of 2.2., which can be applied to concrete. It will dig into the capillaries of the concrete preferably when the concrete is slightly wet. The perfect solution. Link to comment Share on other sites More sharing options...
Anthony5 Posted April 18, 2015 Share Posted April 18, 2015 Shell Flintkote +1 for flintkote. Used it for my roof ridges that were leaking, and works a charm. Available in home pro or other hardware stores. Link to comment Share on other sites More sharing options...

Gulfsailor Posted August 25, 2016 Share Posted August 25, 2016 Make sure the concrete was cured for at least a month (Longer is better) if it's a new structure. If it is an existing structure sandblast it to clean or use an acid to etch the surface. Then use an epoxy primer (water bond types can be thinned with water, otherwise there are dedicated thinners for epoxy). If the surface will be in the shade you can use an epoxy topcoat. If it's in the sun use a polyurethane topcoat, as that will withstand the UV much better. Use different dedicated thinner for polyurethane. Follow the coating instructions carefully for the best result. Link to comment Share on other sites More sharing options...
