MINERALIT RESTAURO MWSK – Micro-mortar for filling gaps and caverns

A mineral injection mortar with very fine grain and high strength for filling holes, scratches and voids (i.e. caverns) in walls. The product after mixing with water creates a liquid and easily pumpable mixture with a rapid increase in strength and high final strength. The material is designed for use in masonry injections.

• No shrinkage
• High compressive strength
• Very good fl ow and cavern penetration
• No sedimentation
Pour about 6.8 litres of clean cold water into a clean mortar container, mix thoroughly and for a long time (approx. 3-4 minutes). Note: Too small amount of water results in insuffi cient liquidity. Both too long and too intensive mixing may lead to excessive aeration of the mortar and, consequently, lowering its strength parameters. When fi lling voids without pressure, pour the material through a funnel. When injecting under pressure, suitable injection equipment should be used. At the earliest, 7 days after the mortar has been introduced, the injection holes should be re-bored with a drill with a diameter about 2 to 4 mm larger and a hydrophobic diaphragm against capillary moisture should be made using MICROSILEX RESTAURO. If it is not possible to meet the timing provided, it can be immediately soaked with the preparation, in which case a second row of holes should be drilled approx. 5 cm higher.
