A-Plus® Plasterbond Cement Admixtures

A-Plus® Plasterbond is a concrete add-mix (slow setting) that serves as a waterproof plastering and bonding aid, as well as a tile adhesive. It improves both the application and end-properties of concrete by enhancing its flow properties during application stage and overall concrete tensile-flexural-comprehensive strength, allowing concrete mix to be easily applied on the substrate without pre-mature gelling and setting.

Surface Preparation & Precautions

Surface Preparation:

1. Surface to be applied must be thoroughly cleaned, free from any contaminants that can affect adhesion such as wax, oil, grease, rust, and loose particles.
2. Avoid applying under extreme environmental conditions and/ or bad weather conditions.
3. Follow accurate mixing ratios for optimum product performance.
4. Dampen surface to enhance grip and adhesion.

Painting Procedure

General Instructions:

Prepare slurry by mixing powder/solid components first then slowly add A-Plus® Plasterbond while mixing. If necessary, add small amounts of water to control consistency.
Clean the substrate free of loose contaminants. Pre-wet surface with water to improve adhesion of slurry.
Apply the slurry on the substrate using the appropriate tool(trowel, heavy brush, etc.) For tile adhesive slurry, a notched trowel is highly recommended.
Follow the correct mixing ratios to maximize product performance.

As Plastering Aid (for creating concrete mix with enhanced strength, durability and water resistance):

Mixing ratio: 1L A-Plus® Plasterbond : 20kg Cement : 60kg Sand : 6L Water
Mix well to a lump-free slurry before application.
Dampen the concrete surface first before applying the slurry. Apply the slurry using a trowel.

As Plastering Aid (for repairing non-structural cracks and imperfections):

Mixing ratio: 1L A-Plus® Plasterbond : 3kg Cement
Mix well to a lump-free slurry before application.
Dampen the concrete surface first before applying the slurry. Apply the slurry using a trowel.

As Bonding Aid (to improve adhesion of new concrete topping to old/existing concrete):

Mixing ratio: 1L A-Plus® Plasterbond : 5kg Cement : 1L Water
Mix well to a lump-free slurry before application.
Dampen the concrete surface first before applying the slurry.
Apply a thin coat of the slurry using a thick brush or roller. Apply the new concrete topping while the bonding aid is still tacky.

As Tile Adhesive:

Mixing ratio: 1L A-Plus® Plasterbond : 8kg Cement : 8kg Sand : 3L Water
Mix well to a lump-free slurry before application.
Dampen the substrate first before applying the slurry. Apply the mixture using a trowel with a thickness of about 3mm or more depending on the type of substrate and tile used. A notched trowel is highly recommended.
Lay down and align tiles. Open time is about 20 minutes. Wipe off excess adhesive mixture with a wet cloth until clean.
Allow at least 24 hours curing time before applying tile grout. Allow at least another 24 hours before subjecting to normal traffic.

As Tile Adhesive (Tile-on-Tile installation):

Prior to application of the tile adhesive slurry, apply a thin coat of bonding aid slurry over the existing tiles. Allow to dry for at least an hour then follow the above procedure for application of the tile adhesive slurry.
