{"product_id":"watco-epoxy-damp-proof-membrane","title":"Watco Epoxy Damp Proof Membrane","description":"\u003cp\u003eWatco Epoxy Damp Proof Membrane is a two part epoxy moisture barrier for interior concrete floors affected by rising damp. It is designed for situations where the original damp proof membrane is missing or ineffective, helping suppress moisture vapour before a compatible floor coating is applied.\u003c\/p\u003e\n\u003cp\u003eThe virtually solvent free, 100% solids formulation tolerates concrete moisture levels up to 98% RH. A full, continuous coat provides the barrier, making preparation and careful inspection particularly important. Suitable projects include industrial and commercial concrete or sand and cement floors where moisture would otherwise interfere with the selected coating system.\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003eEpoxy moisture barrier for floors with an absent or defective DPM.\u003c\/li\u003e\n\u003cli\u003eTolerates moisture levels up to 98% RH.\u003c\/li\u003e\n\u003cli\u003eDark Grey finish helps show complete coverage.\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eSurface Preparation\u003c\/h3\u003e\u003cp\u003eEnsure the concrete is sound and free of contamination, weak material and dust. Mechanical preparation by shot blasting or scarifying is preferred, followed by thorough vacuuming. Smooth power floated concrete requires mechanical preparation. Turn underfloor heating off at least two days before application and leave it off for two days afterwards, then restart gradually.\u003c\/p\u003e\u003ch3\u003eTechnical Data\u003c\/h3\u003e\u003ctable\u003e\u003ctbody\u003e\n\u003ctr\u003e\n\u003cth\u003ePack size \/ colour\u003c\/th\u003e\n\u003ctd\u003e8kg \/ Dark Grey\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eComposition\u003c\/th\u003e\n\u003ctd\u003eTwo part, 100% solids epoxy\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eUse\u003c\/th\u003e\n\u003ctd\u003eInterior concrete and sand and cement\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eMoisture tolerance\u003c\/th\u003e\n\u003ctd\u003eUp to 98% RH\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eMinimum conditions\u003c\/th\u003e\n\u003ctd\u003eAir 15°C; floor 10°C\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003ePot life \/ shelf life\u003c\/th\u003e\n\u003ctd\u003e1 hour at 15°C \/ 6 months unopened\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/tbody\u003e\u003c\/table\u003e\u003ch3\u003eCoverage\u003c\/h3\u003e\u003cp\u003eAllow approximately 20–25m² per 8kg at a wet film thickness of 250 microns.

Do not rely on a thin, patchy coat over highly porous concrete. Flowtop and similar screed or repair overlays can require two coats with the second sand blinded; follow the full system instructions. Condition material at 15–25°C for at least eight hours and protect from freezing.
