Sealant compatibility header


On a regular basis, Palram attempts to purchase sealants that are available from a variety of home improvement centers and lumber yards. These sealants are tested for compatibility with Palram's polycarbonate. Unfortunately, it is difficult to reliably test and publish comparative adhesive strength of each sealant. Be aware that different sealants provide varying degrees of adhesive capacity.

Manufactures of sealants sometimes change the formulas for their sealants without notice. As a result, Palram can only guarantee the compatibility of the sealants based on the formulas used at the time tested (see list for testing date).

Use of incompatible sealants can potentially ruin your hard work, and worse, will likely void your warranty. For a detailed list of sealants that have been tested, click on the link below. If you would like to submit a sealant for testing, please use the instructions below.
