Base paint - PASTI GRUNT
USE
PASTI GRUNT is a priming mass used for substrate preparation under thin-layer plasters and gypsum plasters. PASTI GRUNT is a general-purpose priming agent for all types of substrates. It can be used on mineral surfaces (e.g. cement plaster, cement-lime plaster), on plasterboard panels and on smooth substrates of very low absorptivity (e.g. concrete walls and ceilings, OSBs). It is suitable for indoor and outdoor use.
PROPERTIES
PASTI GRUNT is a ready-to-use priming mass based on quartz flours and acrylic resins. It is a white priming agent. Additionally, it is available in variety of as a prime coat for selected colours of PASTI KWARC mosaic plasters. It is efficient, very convenient and easy to use. Aggregate content enhances surface coarseness, making application of successive layers easier, and increases the contact area of the plaster or adhesives with the substrate. Application of PASTI GRUNT improves adhesion and prevents appearance of stains on the thin-layer plaster resulting from inappropriate substrate preparation or its properties.
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 plaster coats of insufficient adhesion.
APPLICATION
Distribute PASTI GRUNT on prepared substrate (evenly on the whole surface) with a roller or paintbrush. Do not apply the mass below +5°C. Begin surface plastering or facing fixing after the mass completely dries i.e. after ca. 4÷6 hours from its application. The information comprises basic instructions of product application and do not relieve users of responsibility for work in accordance with good construction practice.
