The Actichem sealer calculator is used to determine the estimated amount of sealer required to seal porous surfaces. It is important to remember that this is a guide, and we still recommend that you conduct a test yourself, to accurately determine coverage for any specific surface.
The Actichem Penetrating Sealer Calculator is provided as a guide only. These calculations are based on a two application coverage for first applications with a usage rate of 10 square metres per litre and a second application with a usage rate of 12 square metres per litre. The coverage rates will vary depending on surface being coated and the particular product being applied. More information on these products can be found on the product label, or by calling our Help and Advice centre on 1800 108 800.
Every effort has been made to ensure the accuracy of the estimate, however sealer requirements may vary depending on the surface, type of sealer or even weather conditions.
