Decorative mosaic plaster - PASTI KWARC
USE
PASTI KWARC is designed for manual preparation of internal and external decorative plaster coatings. It can be used on all even mineral substrates such as concrete, traditional cement plasters, cement plasters, plasterboard and wood-based panels and reinforced layers of thermal insulation systems of buildings. It is particularly recommended for pedestals, foundations, balcony walls, etc. A wide range of available colours allow for a large degree of freedom in the design and finish of exhibition rooms, car dealerships, offices, staircases, as well as residential and public areas.
PROPERTIES
PASTI KWARC is a ready-to-use plaster based on acrylic resin with the addition of coloured quartz aggregate. It is efficient, convenient and easy to use. It provides hydrophobic layer permeable for water vapour characterised by low stress concentration. High content of pure polymer ensures its exceptional resistance to various kinds of damage, weather conditions, washing, abrasion, etc. Note: PASTI KWARC is milky-white when applied. It obtains its full proper colour when dried. High air humidity and low temperature may extend the setting time and change colour shades. In case of constant contact with water, the plaster may go milky white; the effect disappears when the surface dries. Therefore, avoid plaster application when it is exposed to long-term effect of water or humidity and elements without appropriate damp insulation.
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, fat, wax. Remove existing paint and render coats of insufficient adhesion.
APPLICATION
Apply PASTI KWARC over prepared and primed substrate as a layer using a float made of stainless steel. Thickness of the layer should correspond with the aggregate grain size. Always smooth wet plaster in the same direction. The lack of uniform plaster texture due to local irregular floating may result in differences in colour shades on the plastered surface. 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 mosaic plaster, apply plaster of the same production date on the same surface.
