Sealer calculator
Sealers Calculator
Enter your area, choose the sealer + finish, and it will calculate the exact Part A + Part B
(and water for Varnish W).
2 coats required: Mix Coat 1, apply, allow to dry, then mix Coat 2.
Coat 1 often uses more on porous surfaces; Coat 2 can be lower only when the datasheet gives a range.
1) Inputs
Varnish W is recommended diluted 15–20% (water).
Coat split rule (datasheet based):
• If the datasheet gives a range (e.g. 100–150 g/m²), calculator uses Coat 1 = high and Coat 2 = low.
• If the datasheet gives a single number (e.g. 100 g/m²), calculator uses same for both coats.
• Typical recoat times: FastProtec ~1–2 hours; others often overnight (site dependent).
• If the datasheet gives a single number (e.g. 100 g/m²), calculator uses same for both coats.
• Typical recoat times: FastProtec ~1–2 hours; others often overnight (site dependent).
