The best way to ensure maximum fracture-free protection for tile, stone and other hard surface flooring is with full floor coverage of 36” ECB® membrane. But what about isolating hairline fractures in substrates? Strip applications of ECB® provide an alternative to full floor coverage and will protect hard surface flooring from isolated cracks. The ECB® Kit is designed for installations using tiles measuring 12" or less and will protect finished floors from lateral substrate movement up to 1/4". The correct positioning of the tile is critical to the successful installation of any ECB® strip applications. Only one side of each tile should be af?xed to the sub?oor. This will allow the sub?oor to move in-plane while ECB® absorbs the stress of that movement. Tile should never be af?xed directly to the sub?oor on both sides of the membrane.
