Sia 7990 siasponge block can be used universally and is distinguished by its easy handling. Thanks to the grain layer on all four sides and around the edges, the block adapts optimally to all rebates, edges and profiles. The specially designed shape guarantees easy work in places where only one side has to be sanded, as well as in round profiles. It can be easily cleaned and therefore used several times.
It is suitable for roughening wood, plastic or metal before applying paint, fine sanding filler, intermediate sanding of lacquer and paint and sanding in rebates and at slight curves.
