Rasping EIFS expanded polystyrene EPS Foam
Rasping the foam is the same thing as sanding the foam. There are basicly two types of rasps for sanding expanded polystyrene (EPS) foam. One is the standard wooden rasp that sandpaper is attached to and the other is a metal rasp that has metal flakes welded to it to create a 12 grit sandpaper. The DuraRasp from demand products is a very good rasp. They last forever. Here is a quick how to rasp; when rasping the expanded polystyrene (EPS) foam the EIFS applicator wants to rasp in circles. Never rasp up and down or straight across or you will dig holes in the foam. As an EIFS applicator you could imagine how you could really mess a expanded polystyrene (EPS) foam wall up with one of these metal rasps. Rasping in large circles makes it easy to sand the wal even. After completing the wall it is a good idea to go over the wall or section you are working on with a large half moon motion from your toes to above your head. This will make sure you sanded level and smooth. There is nothing worse than getting all done with your job and having it look all wavy.
