A-Plus® Skim Coat 501 Setting-Type Smooth Rendering Paste is a high performance bonding paste designed to be mixed with cement or gypsum powder then applied on concrete substrates to smoothen and correct surface imperfections prior to painting. This product, once mixed with cement or gypsum powder, forms a setting-type thin plaster that imparts a luxuriously smooth and very durable finish for concrete walls and ceilings. Mix with cement powder for skim coating of exterior or heavily-exposed substrates. Use gypsum powder for indoor areas only.

Painting Procedure

Application Procedure:

Follow proper surface preparation for new concrete.
Make sure surface is clean and dirt-free. On very hot conditions (i.e. outdoor application) prevent pre-mature drying of skim coat by slightly misting/dampening the surface using a rag/sponge soaked in water.
Thoroughly mix sieved portland cement and A-Plus® Skim Coat 501 at ratio of 1Kg :1L in a clean mixing container. Pot life is approximately 4 hours.
Apply the slurry using a clean and smooth steel trowel or spatula. Press firmly for an even and thin coat. Recommended thickness is 0.3 to 4.0mm.
Allow to dry for at least overnight before sanding and painting.

Suggested Painting System on Concrete Surfaces:

Waterproofing(Optional): For positive side waterproofing on areas such as Firewalls, Bathroom, Roofdecks, Basements, etc., apply 3-4 coats of a mixture of A-Plus® Concrete Bond with portland cement at 1-Ltr to 1-Kg ratio. Pot life is approx 4 hours. Allow 2-3 hours drying between each coat.
Thin Plaster: Apply mixture of thoroughly mixed sieved portland cement and A-Plus® Skim Coat 501 at ratio of 1Kg :1L using either a spatula knife/steel trowel. Pot life is approximately 4 hours
Sealer: Observe proper concrete curing schedule. Apply 1-2 coats of A-Plus® Concrete Sealer using either brush or roller.
Primer(Optional): Apply at least 1-2 coats of A-Plus® Premium Acrylic Flat Latex as primer.
Topcoat: Apply 2-3 coats of your choice color of A-Plus All Weather® Paint. Allow 2-3 hours drying time between each coat.
