Gyplast Mortar is a thick smoothing plaster for rough substrates, supplied as a whitish powder. It is ready for manual application after adding the specific amount of water. It is mechanically mixed and automatically packed with constant tested ratios, composed of primary raw materials and high-quality additives that enhance its performance. Natural elements constitute more than 98% of the total weight. After adding the right portion of clean water, it forms a homogeneous mortar ready for application without any additional additives. This product can act as a first thick smoothing coat for rough substrates, such as Gyplast Fill or traditional sand and cement plaster, to repair them and achieve the required lining. After setting, Gyplast Mortar provides a hard and smooth coat and exhibits very high adhesion to different types of substrates, especially Gyplast Fill, with minimal waste.
