Non-absorbent compressible white closed cell polyethene foam backup material. Compatible with all know types of sealants to control the depth of the sealant in proper relation to joint width. Provides backing against which the sealant is applied, forcing the sealant to the sides of the joint for adhesion. To ensure you choose the correct size, select a backer strip width that is approximately between 15 and 25% larger than the width of the joint to give a firm base. The backer strip can be compressed down into gaps slightly tighter than its width.
