Product details
Tile and Floor Care Coolcrete concrete stain can be applied to new or old concrete. The concrete must be unsealed and porous, so that the stain can penetrate and react. How it works is that the metallic salts in an acidic water based solution react with the calcium hydroxide (free lime) in the hard concrete and yield insoluble permanent colours. The colours achievable are variants of three basic colours groups.
These colour groups are black, brown and blue/green. The acid in the Coolcrete solution open the surface of the concrete and then the water causes the "rusting" re-action. The re-action begins immediately but can continue to develop for up to a month.
There are other factors that could determine the outcome of the colour:
Age of the cement.
Moisture content of the cement.
Age of aggregate in cement siliceous aggregates such as gravel do not react with the stain.
Floated, powder floated or trowelled finish. Weather conditions during stain application.
Efflorescence. Preparation method before application. Newly laid floors contain more free lime than older established floors so Coolcrete will develop more colours on new cement floors.
