Potassium Densifier Application: When Lpd Is Applied

CETEX LPD is potassium silicate based, which hardens a wide variety of cementatious surfaces. When LPD is applied, it penetrates and reacts with the free calcium hydroxide to produce a Calcium Silicate, which fills up the pores on the surface. This aids in waterproofing and anti-carbonation treatment of concrete surface.

ADVANTAGES
* Penetrates into the surface to harden and decrease the porosity of the surface.
* This restricts the passage of water through the pores.
* This helps in curing of wet concrete and water proofing of set concrete.
* It improves the light reflectance and on polishing the surface results in permanent and attractive sheen.
* It provides a tough protected surface that does not discolor or show pedestrian or vehicular wear marks.
* Improves the abrasion resistance of the surface.
* It is more stable and has lower efflorescence compared to than sodium based compounds
* It improves resistance of the surface against various gases and liquid chemicals .
* 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., should be removed. Fill and repair all holes, cracks and deteriorated areas. For best result, the surface should be dry to allow LPD penetrate the pores and react.

- For good result LPD is diluted with water in 1:3 ratio. 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 LPD to keep the surface wet for 20 minutes. If areas dry out before that, apply more diluted LPD. 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 12 hours.
