A powdered air-drying compound that is ideal for bedding of X-Block® plasterboard joints, angles, spotting fastener heads and filling in gaps to provide a uniform X-ray radiation barrier. Please note: paper tape must be used for all jointing.
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.
