Painting Procedure

General Application Procedure for Normal Substrates with No Damage:

1. Thoroughly clean the surface prior to application. Pre-wet surface with water to improve adhesion.
2. Prepare a lump-free slurry of cement by mixing A-Plus Water-Check® 2K Cementitious Waterproofing Membrane with portland cement at ratio: 1-Ltr to 1-Kg. Pot life of mixture is approximately 3 hours after mixing.
3. Apply first coat mixture using stiff brush. Succeeding coats may be applied using a heavy roller. Repeat up to 3-4 number of coats and allow 2-3 hours drying in-between coats. Allow to cure at least 12-24 hours before subjecting to water flooding test or before applying paint or concrete topping.

Procedure for Damaged Substrates (with cracks and other surface imperfections):

1. Mix A-Plus Water-Check® 2K Cementitious Waterproofing Membrane with portland cement at ratio: 1-Ltr to 3-Kg. The ratio can be varied slightly to achieve desired consistency. Mix thoroughly until a smooth consistency is achieved. Pot life of mixture is approximately 3 hours after mixing.
2. Apply the mixture on the affected areas using a trowel or putty knife. Let cure for 2 hours before applying succeeding coats of A-Plus Water-Check® 2K Cementitious Waterproofing Membrane cement slurry.
3. If higher strength repair is required, apply a mixture of A-Plus Procrete® High Viscosity Construction Epoxy for patching larger-sized concrete imperfections covering smaller areas.
4. After patching surface imperfections, apply normal cement slurry of A-Plus Water-Check® 2K Cementitious Waterproofing Membrane and portland cement with ratio: 1-Ltr to 1-Kg using a stiff brush or heavy roller.

Suggested Painting System on Concrete Surfaces:

1. Sealer: Observe proper concrete curing schedule. Apply A-Plus® Concrete Sealer or A-Plus Acmelux® Penetrating Sealer using either brush or roller.
2. Waterproofing: For positive side waterproofing on areas such as Firewalls, Bathroom, Roofdecks, Basements, etc., apply 3-4 coats of a mixture of A-Plus Water-Check® 2K Cementitious Waterproofing Membrane with portland cement at 1-Ltr to 1-Kg ratio.
3. Primer: Apply at least 1-2 coats of A-Plus® Premium Acrylic Flat Latex or A-Plus Acmelux® Primer White as primer.
4. Putty: Repair all minor cracks and surface imperfections with A-Plus® Concrete Putty or A-Plus Acmelux® Cast. For a luxuriously smooth finish, apply A-Plus® Skim Coat 501/503.
5. Topcoat: Apply 2-3 coats of your choice color of A-Plus All Weather® Paint or A-Plus Acmelux® Topcoat Paint. Allow 2-3 hours drying time between each coat.
