Directions for Use: Best results are obtained in warm (minimum 15°C), dry conditions with a good through draught.

Apply using a brush and/or long pile, double arm roller.

On bare concrete floors: It is recommended that the first coat be diluted with approx. 10-20% Firwood 114 Low odour thinners by volume prior to application. This will act as a binding primer and help seal the concrete surface. Once dried, a second coat can be applied at full strength.

On previously painted floors: It is recommended that two thin coats be applied rather than one thick coat. This will prolong the life and performance of the coating.

Keep coated areas dry for a minimum of 24 hours following application

Foot traffic can be allowed on the coated area after 24 hours and heavier traffic after 72 hours.


Clean application equipment immediately after use with Firwood 114 Thinners

Laitance on concrete - The surface of concrete can have laitance which will flake off with wear. We recommend the use of Firwood 2709 Concrete Etching Fluid to remove surface laitance prior to the use of this floor seal.

Product Reviews
Used in our wedding venue
By N R E Willcocks from Suffolk on October 13rd 2019
Just ordered another batch having fist used it about 6 years ago to seal the power-floated concrete floor in our wedding barn. After a lot of use, spills and cleaning, it is only just now needing a further coat. Gives a great unobtrusive finish.
