How much floor stripper do I need per square metre?

Typically you need 1 litre of neat stripper per 10-15 m² depending on the floor type and number of existing polish layers. Heavily built-up floors may need a second application. Always dilute stripper according to the manufacturer instructions — common ratios are 1:3 to 1:5 with water.

How many coats of seal should I apply?

For a durable finish, apply 4-5 coats of sealant on a freshly stripped floor. Each coat should be thin and even, applied with a clean flat mop. Allow 20-30 minutes drying between coats. In high-traffic areas, consider 5 coats for extra protection.

How long does a strip and seal take?

A typical 50 m² room takes 3-5 hours including stripping, rinsing, drying, and applying 4 coats of seal. Larger areas take proportionally longer. Stripping is the most time-consuming part — allow extra time for heavily built-up floors.

Do I need to rinse the floor after stripping?

Yes, thorough rinsing after stripping is essential. Any stripper residue left on the floor will prevent the sealant from bonding properly, causing peeling and poor finish. Rinse at least twice with clean water and allow to dry fully before sealing.

How We Calculate This

How the calculation works

This calculator estimates both stripper and sealant volumes based on floor area, type and desired number of seal coats.

Formulae

Stripper volume = floor area ÷ stripper coverage rate

Sealant per coat = floor area ÷ sealant coverage rate

Total sealant = sealant per coat × number of coats

Coverage rates

Stripper: 10-15 m²/litre depending on floor type
Sealant: 25-40 m²/litre depending on floor porosity
