Our concrete sealers come in 20L tins and drums — One 20L tin will cover approximately 80–100m².
To calculate how much sealer you need, firstly workout the total square meter area of your concrete surface. One litre of sealer will do approximately 4-5m² of concrete.
Formula:
Total surface area m² ÷ 4.5 = amount of litres needed.
Example:
180m² ÷ 4.5 = 40 litres needed
Total tins needed = 2 tins (20L in each tin)
