TECHNICAL SPECIFICATION

Tile and stone terminology can be confusing at times. Below, we've described the Moisture Rating (MR) term you might find on our website or product sheets to help you better understand our products.

MR (MOISTURE RATING)

DENSITY OF TILE DETERMINED BY WATER ABSORPTION RATE.

Tile suitable for exterior applications must have a very low water absorption rate, especially in climates subject to freezing and thawing cycles. For best results and absorption rate should be MR 1 - less than 0.5%.
