AW - 42 - CL

Densifier AW-42-CL is a chemically reactive silicate,producing extremely hard and dense calcium silicate hydrate(CSH) in the pores. It changes the chemical composition of surfaces filling the pores and capillaries of the concrete matrix with hard dense crystals to provide an increase in surface density, durability, dust-proof, and abrasion resistance.

Uses

Densifier AW-42-CL can be used in areas that would benefit from this process including floors subjected to medium or heavy forklift and tow motor traffic; including those found in warehouses, distribution centers, industrial plants, logistics, and most concrete floors needing rehabilitation. Other uses include concrete floors subjected to frequent or heavy pedestrian traffic, such as: exhibition centers, shopping malls, stadiums, docks, railway platforms, parking lots, hospitals, airports, museums, schools and grocery stores, etc.

Advantages

Suitable for interior or exterior applications.

Reduces porosity and Increases surface density and durability.

Can be applied to new or existing concrete.

Provides better abrasion resistance than conventional hardeners.

Breathable and UV stable. Will not yellow, discolor, peel or flake.

Non-flammable. Non-toxic. Odorless. Low VOC.

Treated surfaces are easy to maintain.

Resists black tire marks.

Non-slip

Will not absorb water or contribute to floor sweating.

Dust-proof

Reinforced concrete hardness.

Environmentally friendly.

Application instructions

1. Substrate quality / Pre-treatment

All substrates must be dry, stable, sound and free of all contaminants such as grease, oil, paint, wax, dust, curing and sealing compounds that will interfere with the penetration the densifier.

The floor must be completely dry before it can be sprayed with Densifier AW-42-CL

2. Application

Apply the Densifier AW-42-CL to the concrete surface by low pressure sprayer.
The concrete must be kept wet with Densifier AW-42-CL for at least 10-15 minutes.
Using a soft bristle broom or floor-scrubbing machine to wipe back and forth on the floor to achieve optimum penetration of Densifier AW-42-CL during this period.
Remove any excess material using a squeegee or cloth mop. (Attention: If any excess material is dried and left on the surface, it will result in unsightly white stains and is difficult to remove.)

3. Consumption

0.15 - 0.25 kg / m²

Note：This figure is theoretical and does not include for any additional material required due to surface porosity, surface profile, variations in level and wastage etc.
