Do you need to tape seams with RedGard?
A:The RedGard Decoupling Mat membrane must be treated with RedGard seam tape on the outer seams and edges when used as a waterproof membrane.
For tile underlays like Durock, Wonderboard, Hardiebacker, Permabase and othersSeams between panels should be treated with 2-inch alkaline resistant mesh tape. A layer of Thinset is then troweled over the seam. This will bring the two boards together and prevent sagging.
Using the flat side of a trowel or paring knife, embed RedGard® Joint Tape into the thin film while it is still wet.. Using firm pressure with the trowel or band knife, work diagonally outward and away from center, being careful to remove any trapped air as the seam tape is applied.
RedGard® Seam Tape is a quick and easy way to cover seams and changes in plane when installing RedGard® Uncoupling Mat and Fabric Membrane to provide waterproofing and vapor protection.
For tile installations that adhere directly to the support;It is highly recommended to apply at least one full coat of "undiluted" RedGard® to the "dry" primed area and allow to dry completely before beginning tile installation work.. When used as a vapor barrier, apply one full coat (70 square feet).
An alkali resistant fiberglass tape for reinforcing RedGard® and RedGard® SpeedCoat® when used over foundation cracks. It can also be used in corners and anywhere there is a drop in the installation for additional reinforcement.
When applying joint compound to drywall joints without tape,Compound seeps through seams, wasting your time and resources. Used to fill the joints between sheets of drywall, joint compound shrinks and cracks as it dries. Tapeless joint compound will crack and peel over time.
The concrete backer board itself is waterproof as it will not degrade when exposed to moisture.. In fact, cement boards can be completely submerged under water without damage. However, it does not waterproof a shower, bathroom or kitchen area by simply installing it.
All drywall seams require masking tape to be incorporated into the joint compound. The tape reinforces the joint and the compound or paste is the glue that holds the tape in place.
RedGard® is dry when it turns solid red with no visible pink color. Usually the drying time1-1.5 hours for each shift. After the second coat has been applied and both coats are completely dry, the application surface can be flood tested.

And. You can tile over Redgard. An additional moisture barrier is not required. So you can apply the thin layer and mosaics on it.
