Colourless Potassium Lithium Silicate - Polisi

POTASSIUM LITHIUM SILICATE

CETEX Potassium Lithium Silicate is a premium mixed silicate. It hardens a wide variety of concrete / marble / stone surfaces. When POLISI is applied, it penetrates the surface and it reacts with the free calcium hydroxide to produce a by-product, which fills up the pores on the surface. Being bigger molecule compared to Lithium Silicate, penetration is lower, hence more suitable for porous surfaces.

ADVANTAGES
* Penetrates into the surface to harden and decrease the porosity of the surface.
* It improves the light reflectance and on polishing the surface results in permanent and attractive sheen.
* Helps reduce damaging alkali-silica reactions (ASR) and protects from weathering and efflorescence
* It provides a tough protected surface that does not dis-colour or show pedestrian or vehicular wear marks.
* By reducing the pores of the surface, it aids in curing of green concrete.
* Improves the abrasion resistance of the surface.
* It does not cause efflorescence and is more stable than sodium.
* It helps in waterproofing & improves the chemical resistance of the surface.
* Protects the surface against scratching or peeling thus making it dustproof.
* Concentrated for easy transportation and can be easily applied.
* It can be applied in both new as well as old constructions.
* It is economical to use.

APPLICATION METHODS
- Clean the surface before application. If there is coating on the surface, for example curing compound etc., it should be removed. Fill and repair all holes, cracks and deteriorated areas. For best result, the surface should be dry to allow POLISI penetrate the pores and react.

- For good result POLISI is diluted with water in 1:3 ratios. It can be applied on clean surface by using a low-pressure sprayer or by spreading evenly with a soft-bristled broom.

- For Horizontal surfaces, apply enough diluted POLISI to keep the surface wet for 20 minutes. If areas dry out before that, apply more diluted POLISI. In hot, dry or windy conditions dampen concrete before application to prevent flash drying. Remove any dried powder residue using a stiff broom, power sweeper or floor scrubbing machine. For immediate, enhanced shine, buff or burnish the dry concrete surface in both directions using an orbital floor machine or burnisher equipped with an appropriate polishing pad. This is a dry buffing operation.

- For vertical surfaces, apply from the bottom up. For maximum penetration and desired coverage rates, a wet-on-wet application is recommended; retreat within three to five minutes after initial application. Repeated applications should be made until the surface remains moist for a minute or so before solution disappears

- Restrict usage of the treated surface for 8 hours.
