Sethard
P

P0TASSIUM SILICATE HARDENER AND DUST PROOFER FOR CONCRETE SURFACES

Advantages:

Improves wear resistance of floors
Reduse the dust
Allows water vapor to come out of the concrete structure
Long - lasting material
One component material
Ease of use

Description:

Sethard P is a transparent surface hardener and dust reduser, designed for application on concrete and cement. Sethard P is based on an aqueous solution of potassium silicate and improved surface hardness. Sethard P chemically reacts with the free lime in the concrete forming dense, wear resistant.

Usage

Sethard P is recommended for new and old concrete surfaces such as concrete floors and pavements granolithic. It is not used for the renovation of crushed, cracked concrete.

Application Instructions

SURFACE PREPARATION

All surfaces must be dry, firm, intact, cleaned of dust, small particles, oils, dirt. Thoroughly prepared surface is essential for maximum penetration of Sethard P.

Contamination by oil, grease should be treated with appropriate chemical degreasers and then be cleaned with water. Deep oil penetrated zones should be cleaned with a jet of hot compressed air.

APPLICATION

On concrete floors

Sethard P can be applied on new concrete after the final smoothing and after evaporate surface water.

Sethard P can be applied on old concrete. The concrete must be completely clean from dirt before applying.

Sethard P is ready for use. It is well stirred prior to application. It ss applied evenly over the entire surface, without forming puddles. Use a machine with a jet of low pressure.

Application temperature: above +5 ˚C.

NOTES

Colored surfaces must be aged 28 days before applying Sethard P. It is recommended to test on a small area to assess the effect of color on Sethard P.

Concrete floors must be completely dry to achieve maximum penetration.
