Sealer
How to apply.
Sand the surface
Lightly sand the microcement layer before sealing.
Remove all dust
Wipe clean with a dry microfiber cloth or mop.
Add all of Part B
Full container: add the entire Part B bottle. Ratio is 83:17 A:B by weight.
Roll on evenly
No heavy areas, puddles, or roller lines. Back-roll in both directions.
Dry and recoat
Follow the specified recoat time before applying the second coat. Recoat time is separate from the cure period before water exposure.
Before water exposure: Allow at least two weeks (14 days) after the final sealer coat before exposing the surface to water. Recoat or touch-dry times do not mean the surface is ready for water exposure. Follow any longer cure period required by the product instructions or jobsite conditions. This does not approve permanent pool submersion.

Specs.
Coverage varies based on substrate and application thickness.
How much do I need?
Enter your square footage. We will work out Part A and Part B for both coats. Ratio is 83:17 by weight: always weigh, never eyeball. One kit is 5.00 kg (Part A 4.15 kg, Part B 0.85 kg). Ounces are scale ounces: weigh them. The millilitres are there if you would rather pour, but weighing is what keeps the ratio right.
