In a move to strengthen its focus in the tile and stone installation products market, Custom Building Products said it has sold its pre-mixed patch and repair products business to DAP Inc., a Baltimore-based marketer of caulks, sealants and patch and repair products. Terms of the deal were not disclosed.

"Custom has grown from a single manufacturing plant 40 years ago to a leading provider of tile and stone installation systems," said Tom Peck, president of Custom Building Products. "This move allows us to focus our entire efforts and resources on the installation products and technology that are most important to our customers."
