{"product_id":"watco-powerfloat-primer-rapid","title":"Watco Powerfloat Primer Rapid","description":"\u003cp\u003eWatco Powerfloat Primer Rapid is a fast drying epoxy adhesion primer for smooth, dense concrete floors. Its water based, two component formulation prepares suitably cleaned power floated concrete for a compatible floor coating, helping reduce the downtime associated with floor refurbishment.\u003c\/p\u003e\n\u003cp\u003eThe rapid formulation is useful in workshops, warehouses and commercial interiors where the programme needs a shorter priming stage. It is supplied in Light Grey and normally needs one roller-applied coat. Although the primer can help where mechanical preparation is difficult, Watco recommends diamond grinding or shot blasting where practical for the best overall result. Cleaning, soundness and correct overcoating times remain essential.\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003eFast drying primer for smooth concrete floors indoors.\u003c\/li\u003e\n\u003cli\u003eWater based, low odour epoxy formulation.\u003c\/li\u003e\n\u003cli\u003eLight Grey finish beneath compatible floor coatings.\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eSurface Preparation\u003c\/h3\u003e\u003cp\u003eRemove oil, grease, dust and weak material. Degrease where required, rinse thoroughly and let the floor dry. Remove surface laitance with a suitable preparation method. New concrete should generally dry for four weeks in summer or six in winter, subject to the intended coating's requirements. Only retain existing paint that is sound, well bonded and correctly prepared.\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\u003e5L \/ 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\u003eUse\u003c\/th\u003e\n\u003ctd\u003eInterior\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; use promptly\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\u003eAllow approximately 30m² per 5L per coat (6m²\/L).

The product page gives a 3–36 hour window for compatible epoxy and polyaspartic finishes at 15–20°C; the technical sheet requires longer minimum waits for some systems, so the application guidance above uses those longer waits. Do not assume every paint can be applied after three hours. Not for bare metal. Seek advice for self-levelling compounds. Store at 15–25°C before use and protect from frost.\u003c\/p\u003e\u003ch3\u003eProduct FAQs\u003c\/h3\u003e\u003cp\u003e\u003cstrong\u003eHow is Rapid different from standard Powerfloat Primer?\u003c\/strong\u003e\u003cbr\u003eThe rapid formulation shortens the waiting time before suitable topcoats.
