Gyplast Top

“Gyplast Top”, is a formula in the form of whitish powder, ready for manual application after the addition of the specific amount of water. It’s mechanically mixed and automatically packed with constant tested ratios, composed from primary raw materials and high quality additives enhancing the product performance. Natural elements compose more than 98% from the total weight. After adding the right portion of clean water, it gives a homogeneous mortar ready for application without adding any additives. It has the ability to smooth the surface that have been plastered by “Gyplast” products or to repair traditional plaster

“Gyplast Top”, after its setting gives a very smooth coat dust free. It also features a very high adhesion to different types of substrates in addition to a very high coverage rates with the lowest percentage of waste. In addition, it can reach up to 3 mm to repair any roughness appearing in the surface even on top of traditional sand and cement plaster or fair-face concrete

Key facts
