Primer
How to apply.
Prep the surface
Clean, dry, solid, and smooth. Imperfections can show through — fix them now, not later.
Mix Part A + B
Full container: mix A with B. Mixing less? Use the 75:25 ratio by weight — the calculator works it out. Pot life is 60 minutes.
Mix with a drill
Slow speed, blend fully for 3 minutes. Do not undermix.
Roll on evenly
On floors, broadcast 60–80 grit silica sand over the wet primer in small sections.
Let dry
Walls: 60 minutes. Floors: 2 hours.

How much do I need?
Enter your square footage and we will work out Part A and Part B. Ratio is 75:25 by weight — always weigh, never eyeball. One kit is 5.00 kg (Part A 3.75 kg, Part B 1.25 kg). Ounces are scale ounces — weigh them. The millilitres are there if you would rather pour, but weighing is what keeps the ratio right.
Every piece of the system.
