P-820 Oil Stop Primer

Black epoxy primer that blocks old oil in the slab from lifting a new floor. Solvent-based: ventilate while you work.

What's in the box

• 1 Gal Kit: 1/2 gal Part A + 1/2 gal Part B
• 2 Gal Kit: 1 gal Part A + 1 gal Part B
• 10 Gal Kit: 5 gal Part A + 5 gal Part B
• Each kit is two parts. Mix Part A into Part B completely before you pour.

What it covers

• 200 to 320 sq ft per gallon at 5 to 8 mils wet
• 2 Gal Kit primes about 400 to 640 sq ft, a 2-car garage, or spot-primes many stains

Coverage figures assume the recommended thickness on a properly profiled slab. Rough or porous concrete uses more. Order the next size up if your floor is at the top of a range.

Use it when

• Drip spots keep darkening after you degrease
• A stain comes back a day after cleaning: the oil is in the slab, not on it

Pick something else if

• The slab is clean and new
