Mapei Canada acquires Diaplas

MAPEI Canada (MAPEI Inc.), a global leader in the manufacturing of adhesives, sealants, and chemical products for the construction industry, is pleased to announce the successful acquisition of Diaplas, a company specializing in manufacturing profiles and trims for floors and walls, based in Laval, Quebec.

Diaplas has been a key local player in the complementary tile accessories market since 1989. The company has one manufacturing site and administrative office in Laval. This acquisition aligns with MAPEI’s vision of providing comprehensive solutions for the construction and industrial sectors, ensuring a more robust and diverse product offering. 

“We are thrilled to welcome Diaplas into the MAPEI family,” said Marco Roma, General Manager of MAPEI Canada. “Diaplas’s existing customers will benefit from access to MAPEI’s extensive distribution network, extensive research and development capabilities, and a broader range of products. MAPEI, in turn, will gain valuable expertise and local production capacity of high-turnover inventory from Diaplas,” he added. 

“With the addition of Diaplas’s specialized manufacturing center in Canada under our portfolio, there will be opportunities for growth and development across North America in this new product category of profiles and trims. This acquisition underscores our dedication to growth, innovation, and customer satisfaction,” said Luigi Di Geso, President & CEO of MAPEI North America. 

Following the acquisition of Profilpas, a European manufacturer of profiles and trims, in 2022,  this acquisition is perfectly in line with our ongoing commitment to expanding our product portfolio,” said Veronica and Marco Squinzi, CEOs of the MAPEI Group. “By doing so we can  serve professionals and distribution partners even more effectively.”

The integration process will involve a collaborative effort to leverage the strengths of both companies and streamline operations for increased efficiency. MAPEI is committed to maintaining the high standards of quality and service that Diaplas customers have come to expect.

As a company committed to sustainability and excellence, MAPEI looks forward to a seamless integration process and anticipates a positive impact on the industry as a whole.
