{"product_id":"watco-oil-block-primer","title":"Watco Oil Block Primer","description":"\u003cp\u003eWatco Oil Block Primer helps prepare oil-contaminated, porous concrete for a suitable heavy duty epoxy floor coating. Its penetrating two part epoxy formulation is intended for residual mineral oil contamination that remains after thorough cleaning, such as on workshop and garage floors that have absorbed oil over time.\u003c\/p\u003e\n\u003cp\u003eGood preparation still matters: remove as much contamination as possible before priming. The primer helps address deep-seated residues that conventional cleaning alone may struggle to remove, creating a base for a compatible 100% solids epoxy finish. It stains the substrate black and must be overcoated; it is a preparation stage rather than a finished wearing surface.\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003eSpecialist primer for residual mineral oil in porous substrates.\u003c\/li\u003e\n\u003cli\u003eSolvent based, two component epoxy resin.\u003c\/li\u003e\n\u003cli\u003eBrush application helps work the primer into the floor.\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eSurface Preparation\u003c\/h3\u003e\u003cp\u003eScrape or grind away as much oil and contamination as possible.
