GIB X-Block® Jointing Compound has been specifically formulated designed for X-ray radiation protection on walls and ceilings and is used together with GIB X-Block® plasterboard, a unique lead-free plasterboard, in the GIB X-BLOCK® system.
An air-drying powder compound, it must be used for the first and second coats of X-Block systems, completely filling the recess for all layers of board in the system.
All Siniat jointing and finishing compounds can be used over X-Block Jointing Compound as a final coat.
Mixes easily to a smooth consistency and is easy to trowel by hand or mechanical tools. GIBX-Block® has high shrinkage to create a denser joint, hence each coat must be fully dry before application of the next coat.
