FEATURES
SimpleBAU Special Primer ULTRA is produced on the basis of a
styrene-acrylate dispersion. It has increased penetration capacity – the product penetrates deep into the substrate, so it does not just work superficially. The product is specially recommended for demanding indoor and outdoor substrates.
It improves uniformity and time of bonding in plastering and levelling work.
In self-levelling screeds, it forms a protective layer, facilitates conservation and prevents dust deposits. At the same time, it protects the surface from harmful chemical reactions between gypsum and cement, prevents rapid water absorption by the substrate and improves the mechanical load-bearing capacity of cement mortar.
After drying, it forms a colourless layer. Primer unifies the absorbency of mineral substrates, reduces water build-up and improves the adhesion of further coats. The product penetrates deep into the substrate and also protects it from moisture.
SimpleBAU Special Primer ULTRA increases the efficiency of glue and mortar – it seals the structure of the primed substrate and increases the adhesion of glue for glazed and terracotta surfaces.
APPLICATION AREA
SimpleBAU Special Primer ULTRA is used as a primer to reinforce old and new substrates with high absorbency such as concrete, porous clay surfaces, plasters (cement-lime, lime, gypsum), boards (cement, gypsum, plasterboard) and sandstone.
It is particularly recommended for use as a substrate primer for levelling compounds, mineral and acrylic plasters, paints, levelling mortars, self-levelling screeds and adhesives for ceramic tiles.
It can be used in heated floor constructions.
SUBSTRATE PREPARATION
The substrate must be dry, clean and free of dust, grease, old paint residues and loose particles that may affect the adhesion of the primer.
Dirt and poorly adhesive coatings should be removed and filled with a suitable material (e.g. plaster, filler).
APPLICATION
The product is delivered ready to use.
Using a roller, trowel or sprayer, apply the undiluted product to the substrate in an even layer.
Apply the undiluted product to the substrate with a roller, trowel or by spraying in an even and thin layer.
If the substrate is still absorbent after drying, the primer should be repeated.
Do not start painting, wallpapering, tiling and the like before the emulsion has dried. The primer should form a matt surface after drying.
The drying time depends on air temperature and humidity and averages 4 hours after application.
