- One-component, flexible, cement-based mortar with total watertightness, obtained from mixed binders, calcareous and siliceous inert materials and additives
- Adheres to any type of cement surface (cement render, concrete)
- Also applicable on ceramic or stone, except in swimming pools or ponds
- Final finish coated in order to guarantee its protection and durability (especially in passable areas)
Do not apply over bituminous coatings. Pre-moisten the support to be coated when it is very hot. After application, care must be taken to protect the waterproofing for at least the first 24 to 48 hours. The mixer water should not contain any impurities (clay, organic matter) and should preferably be potable. Do not apply product that has started to set or softened compounds. Do not add any other products to the mortar, applying the product as presented in its original packaging and prepared according to the respective recommendations.
Waterproofing balconies, bathrooms and underground buildings (basement walls and foundations).
The support must be regular, clean and free from grease. Application only after complete removal of dust, efflorescence, release agents, splatter and rust. Absorbent surfaces must be pre-moistened with water. Proceed with the treatment of singular points, such as expansion joints and finishing areas where the floor meets the wall with IsolBand (5875120010) - waterproofing reinforcement. Mix mechanically, with 4.2 litres of water per 20 kg bag, with an electric mixer at low speed, until a smooth, consistent and lump-free paste is obtained. Use a metal trowel to apply in two layers with the addition of fibreglass mesh with anti-alkaline treatment (90 gr/m²). Apply the first layer of Hidroblock 1K and place the mesh over this layer while it is still fresh. Once it hardens (around 3 to 5 hours) apply a second cross coat. The mesh must always be between two layers of product and never directly on the support. Hidroblock 1K can also be applied by roller or brush. At least three coats must be applied in this case. The final thickness must be at least 2 mm. Leave for 2 days before proceeding to bond the ceramic tile. For other situations not mentioned in this technical document, we recommend contacting our technical services in advance.
