Potassium Hardener

Product Description

CETEX DLPD is potassium silicate based, which hardens a wide variety of cementatious surfaces. When DLPD is applied, itpenetrates and reacts with the free calcium hydroxide to produce a by-product,which fills up the pores on the surface. This aids in trapping the moisture ofwet concrete, which aids in curing of wet concrete.

ADVANTAGES                              

Penetrates into the surface to harden and decrease the porosity ofthe surface.

This restricts the passage of water through the pores

This helps in curing of wet concrete and water proofing of setconcrete.

It improves the light reflectance and on polishing the surface resultsin permanent and attractive sheen.

It provides a tough protected surface that does not discolour orshow pedestrian or vehicular wear marks.

Improves the abrasion resistance of the surface.

It does not cause efflorescence and is more stable than sodium.

It improves the chemical resistance of the surface.

Protects the surface against scratching or peeling thus making itdustproof.

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. Ifthere is coating on the surface, for example curing compound etc., should beremoved. Fill and repair all holes, cracks and deteriorated areas. For bestresult, the surface should be dry to allow DLPDpenetrate the pores and react.

For good result DLPD is diluted with water in 1:3 ratio. It can be applied on cleansurface by using a low-pressure sprayer or by spreading evenly with asoft-bristled broom.

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

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

Restrict usage of the treated surface for12 hours.
