Question 4

What is the purpose of movement joints or expansion joints in tile installations?

Accepted Answer

They allow differential movement between tile substrate and structure to prevent cracking

Answer

Movement joints filled with flexible sealant accommodate differential movement from thermal expansion, substrate deflection, and building settlement to prevent tile or grout cracking.

Question 5

What is the key difference between sanded and unsanded grout?

Accepted Answer

Sanded contains fine aggregate for joints over 1/8 inch; unsanded is smoother for narrower joints
