Product description
WULFF Micro-Grund is the first dispersion primer awarded the prestigious Blue Angel eco-label (RAL-UZ 113).
It is characterised by an exceptionally fine-grained structure that enables deep penetration into the pores of the substrate and develops superior adhesion. It effectively binds residual surface dust and regulates uniform absorbency of mineral substrates.
Drastically improves the flow properties of self-levelling compounds — smoother surface, lower compound consumption, faster installation. Formulation with the lowest emissions (GISCODE D1, solvent-free).
