FAQ

What is the difference between Weberset 353 and 303?

353 is a C2TE-rated high-flexibility adhesive with stronger bond strength than 303, suitable for large-format tiles and natural stone. 303 is a C1TE-rated standard strength adhesive for general applications with small to medium tiles. Choose 353 for large tiles or stone, and 303 for standard-sized tiles.

What is the difference between 353 and 383?

353 is C2TE rated, while 383 is C2TES1 rated — the S1 designation indicates additional flexibility, suitable for substrates subject to vibration or deformation and extra-large tiles. 353 is sufficient for most large tile applications; use 383 for challenging substrates or oversized tiles.
