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.

Base binder: portland cement, modifiers;
Mixing ratio:approx. 6.8 l per 20 kg bag
Efficiency: from one package of the product, after adding the appropriate amount of water, we can obtain approx- imately 14.5 litres of ready-to-use product
Temperature of application (air and substrate): from +5°C to +25°C;
Shelf life: 12 months from the date of production printed on the packaging. Protect against moisture
Bending strength of hardened mortar after 7 days of maturing4.8[N/mm2];
Bending strength of hardened mortar after 28 days of maturing7.8[N/mm2];
Compressive strength of hardened mortar after 7 days of maturing23.3[N/mm2];
Compressive strength of hardened mortar after 28 days of maturing33.6[N/mm2];
Water absorption coeffi cient caused by capillary action of hardened mortar after 24 h0.15 [kg/m2];
Modulus of elasticity E;10.0 [GPa];
Packaging: Disposable paper packaging containing 20 kg of product
Storage: The product should be stored in original sealed packaging, in dry rooms, on pallets, at a temperature ranging from +5°C to +25°C

• 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.
