Sandblasted base for wooden surfaces, easy to apply, ideal for professional use, excellent with filling capacity and adhesion on different wood types, and fast drying, which reduces painting time. Forms a background film as to ensure the adhesion of the topcoat ensures a uniform film formation. Composed with acrylic resins in aqueous dispersion, suitable for painting of artefacts indoors and outdoors; ensures good wetting of the pores in the wood with low swelling of the fibre. It is sand blastable and brushable manually or mechanically. The film is particularly elastic and remains unaltered to the dimensional changes of wood exposed outdoors.
