Acrylic plaster - PASTI FIN
USE
PASTI FIN is thin-layer structural plaster designed for manual preparation of decorative external and internal plaster coatings. It can be used on all even and structurally sound mineral substrates such as concrete, traditional cement plasters, cement plasters, plasterboard panels and reinforced layers.
PROPERTIES
PASTI FIN is ready-to-use plaster (in paste consistency) based on water dispersion of synthetic resins and dolomite aggregate with grain size: from 1.0 mm to 2.0 mm. PASTI FIN is efficient, convenient and easy to use. When dry it provides hydrophobic layer permeable for water vapour. It is very resistant to various damages, weather, washing, etc. Moreover, PASTI FIN contains organic agents that reduce fungi and mould development on render surface. PASTI FIN acrylic plasters are available in variety of colours.
SUBSTRATE PREPARATION
The substrate should be stable, even and structurally sound i.e. strong enough; it should be free from anything that may weaken adhesion, in particular dust, dirt, lime, oil, grease, wax, remains of emulsion and oil paint. Remove existing paint and plaster coats of insufficient adhesion.
APPLICATION
Apply PASTI FIN over prepared substrate as an even layer using a float made of stainless steel. Thickness of the layer should correspond with the aggregate grain size. Remove excess of material, place it in the bucket and mix. Form texture of the surface using a float made of plastic with circular moves. Open time of the mass (between mortar application and floating) depends on substrate absorptivity, ambient temperature and mass consistency. Experimentally (for a given type of substrate and given weather) determine the maximum area that can be prepared in one technological cycle (application and floating). Apply the mix using the “wet on wet” method, preventing one batch from drying before application of another one. Otherwise the “seams” will be visible. Plan technological gaps in advance e.g. in corners or building angles, under rainwater pipes, etc. Protect the plastered surface during work and when it dries from direct sunlight, wind and precipitation. Note: to avoid differences in colour shades in case of colour acrylic plasters, apply plaster of the same production date on the same surface. If the plasters are used in thermal insulation systems, avoid dark colours with reflection coefficient of scattered light below 20%. Share of the plasters in such colours should not exceed 10% of façade surface.
