Coarse foam effect rollers for decorating and structuring. Decorating: take the desired colour directly with the coarse foam effect rollers from the container and apply it to the surface as desired. Interesting effects also occur when rolling uneven with the coarse foam effect rollers. Structure: first apply the desired plaster with a trowel. Then structure the mounted plaster with the coarse foam effect rollers. Remove excess material from the coarse foam effect rollers from time to time. Tips: Start on a sample surface (piece of wallpaper or cardboard) to develop a feeling for the coarse foam effect rolls. This allows you to work in the coarse foam effect rollers at the same time. Please note the processing time of the paint material used. Avoid rolling over already designed surfaces with the coarse foam effect rollers several times so as not to destroy the existing effect.
