Contop S is ready to use and can be sprinkled over the surface with a watering can or by soft broom. Contop S should be spread evenly and brushed in well. Bubbles should not be allowed to form. For most concrete 2 coats are sufficient. However, for particularly porous concrete athird coat may be required. 24 hours should be allowed between application of each coat. After the final treatment the surface should be washed down with water. Agitate before use.

IMPORTANT NOTES
The surface treatment of the concrete by power floating or vacuum dewatering can make the surface of the concrete very dense and impermeable. After such treatment it is advisable to test a small area of concrete prior to the application of Contop S to ensure that impregnation occurs and that the surface is not made glassy or white.

COVERAGE RATES
Depending on the porosity up to 6 m2/litre/coat.

Contop S is based on sodium silicate. Wear protective clothing and void skin contact. If contacted wash well with water. If eyes are effected wash with clean water and obtain medical attention.
