5 Instructions
Application of Product
Install SpiderWeb II Uncoupling Mat according to product instructions.
To minimize installation duration, measure and cut the seam tape to
size with a utility knife ahead of mixing thin-set for installation. Once
the mat is installed, apply thin-set mortar into the top of the uncoupling
mat where the seam tape will be applied. Using the flat side of a
trowel or a taping knife, embed the SpiderWeb II Seam Tape into the
still wet thin-set. Work the trowel or taping knife at angles out and
away from the center taking care to work out any air that may have
been trapped when the seam tape was placed.
Protection
If tile or stone will not be set immediately after curing, protect the
application from heavy traffic damage. Protect from rain and inclement
weather for 72 hours after application. If delays longer than 72 hours
are expected, cover the area with felt paper. Care should be taken to
prevent the application from becoming soiled or punctured during and
after application.
Cleaning of equipment
Clean tools and hands with water before the material dries. Clean all
spray equipment immediately after use.
Health Precautions
Wear rubber gloves and eye protection while using this product. Avoid
eye contact or prolonged contact with skin and wash thoroughly after
handling. If eye contact occurs, flush with water for 15 minutes and
consult a physician. Wash thoroughly after handling. Do not take
internally. Keep out of the reach of children.
Conformance to Building Codes
Installation must comply with the requirements of all applicable local,
state and federal code jurisdictions.
