Siena Fracture Shield is a ready to use anti-fracture, crack isolation and water resistant membrane, manufactured with a mixture of latex polymers and other proprietary additives to produce a high quality elastomeric barrier that protects tile floors from cracks due to minor surface movement. Fracture Shield is easily applied with a trowel, roller or brush, and appears glossy white when wet and becomes a flat white upon drying. Fracture Shield exceeds the requirements for ANSI A118.12 for crack isolation and can be used in residential, commercial, interior and exterior tile and stone applications.
Basic Uses
Siena Fracture Shield is used on recommended substrates as an anti-fracture and crack isolation membrane used to prevent shrinkage or non-structural cracks up to 1/8” transmitting from the substrate through the finished goods. Use polymer modified mortars meeting ANSI A118.4 or A118.11 for tile or stone installations over membrane.
