Its water based, two part epoxy formulation helps seal porous concrete to reduce air-entrapment bubbles in the subsequent high build finish, while also providing adhesion on suitable hard, smooth concrete.\u003c\/p\u003e\n\u003cp\u003eA porous unsealed floor can release air into a heavy resin coating during application and cure. Priming first helps control this and creates a more consistent base for the specified finish. The Light Grey primer is designed for interior use on bare, unsealed concrete, including suitable power floated surfaces. Use it as part of the named Epoxicote High Build system rather than as a general-purpose primer for unrelated paints.\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003eSeals porous concrete before a high build epoxy finish.\u003c\/li\u003e\n\u003cli\u003eHelps reduce air-entrapment bubbles.\u003c\/li\u003e\n\u003cli\u003eOne coat, applied by roller.\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eSurface Preparation\u003c\/h3\u003e\u003cp\u003eRemove contamination, loose material and surface laitance. If Etch \u0026amp; Clean is used where appropriate, rinse thoroughly and allow to dry. Slight residual damp after cleaning is acceptable according to the application guidance, but concrete moisture must remain below 75% RH. New concrete should generally dry for four weeks in summer or six weeks in winter. Confirm the preparation needed for especially smooth or polished areas.\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\u003e3L \/ Light Grey\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eComposition\u003c\/th\u003e\n\u003ctd\u003eTwo part, water based epoxy\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eSuitable substrate\u003c\/th\u003e\n\u003ctd\u003eBare, unsealed concrete\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\u003c\/th\u003e\n\u003ctd\u003eUp to 2 hours at 20°C\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eShelf life\u003c\/th\u003e\n\u003ctd\u003e24 months unopened\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/tbody\u003e\u003c\/table\u003e\u003ch3\u003eCoverage\u003c\/h3\u003e\u003cp\u003eApproximately 18m² per 3L for one coat (6m²\/L).

Not suitable for bare metal; most self-levelling compounds require specific advice before painting. Do not treat the primer as a final wearing surface.
