Decorative acrylic plaster for façade rendering
Decorative plaster based on aqueous dispersion of styrene-acrylic resins, natural aggregates, pigments, and waterproofing special additives. It is suitable to be applied on exterior and interior surfaces of concrete, mortar, mineral plaster, masonry and as the finishing coat over thermal insulation systems. It presents very good water vapor permeability and it is resistant to rain, frost and air pollution contributing to long-lasting protection of facades. It bonds perfectly to all types of traditional renders and to old, well-bonded coatings and gives a uniform, attractive finishing. It is ready to use and can be tinted in a wide range of shades.
» High hydrophobicity
» High UV resistance
» Tough uniform finishing
SURFACE PREPARATION AND APPLICATION
To ensure proper adhesion the surface must be dry, clean and free of dust, oil, salt, rust, loose paint and residues, blistered paint etc. Remove all moss, fungi, and algae by mechanical abrasion and wash with soapy water and allow the substrate to dry. Use KRAFT PUTTY or other suitable repairing material of KRAFT to fill gaps, cracks and other damaged surfaces.
» It is recommended that fresh concrete, stucco, plaster and gypsum surfaces are allowed to dry for at least 4 weeks before the application of BASIC PLASTER.
» On porous, new surfaces or already painted substrates and on mineral base coats of ETICS apply one coat of PLASTER PRIMER.
» After 24 hours apply one coat of BASIC PLASTER with stainless steel trowel, and level the coat to the size of the grain with a plastic trowel. On wide surfaces it is recommended to apply without interruption, wet on wet, in order to avoid visible joints.
» Tools: Stainless trowel.
» Cleaning of tools: Immediately after the application, the tools must be cleaned with warm water and soap or a detergent solution. Remove as much material as possible from tools before cleaning.
» Dilution: Does not required.
» Touch to dry time: 1-2 hours at 25ºC and RH 50%.
» Superficial Drying time: 24 hours, at 25ºC and RH 50%.
» Complete through drying time: 7 days, at 25ºC and RH 50%.
» Unfavorable conditions delay drying which can cause surface eﬀects because of the water-soluble additives especially in deep colors. These eﬀects are normally removed automatically on further weathering.
» Stir well with a flat paddle, before application, and at regular intervals during application.
» Do not apply at temperatures below 10ºC or above 35ºC or at humidity levels above 65%.
» Do not apply if rain is imminent.
» Protect the newly applied area from direct sunlight, strong wind and rain by using waterproof sheeting placed so as to avoid contact with the painted surface.
