A:  Hello, Unfortunately, we do not have a point of reference for a temporary install. Something like this would probably be determined by the type of adhesive used. We apologize for not having more information on this type of installation. Best regards, NMC

A:  Hello, We do not recommend this kind of install. With the way our moldings are installed there won't be room to place an LED light. If you were to change the installation method to make room for the light strip it could compromise the molding's ability to stay attached to the wall. Best regards, NMC North America

A:  The same as used in the tutorial video on the product site - DAP Alex plus acrylic latex caulk plus silicone. It worked great. I also recommend putting on 2 coats of primer before topcoating.

A:  Any latex-based caulk will work great. Sometime the label will read as 'acrylic caulk'. Just be careful not to use a caulk that is silicone or petroleum based. They will slowly degrade the moulding. Here is a great recommendation: https://www.homedepot.com/p/DAP-10-1-oz-Alex-Fast-Dry-White-Acrylic-Latex-Plus-Silicone-Caulk-18425/100634323
