It is not a replacement for flexible waterproofing membranes and is not recommended for structures subject to severe movement or deformation that could cause cracking. It should also not be used to waterproof fresh concrete that is still subject to plastic shrinkage.\u003c\/p\u003e\n\u003cp\u003eFor effective waterproofing, the mortar must be correctly formulated, prepared and applied in accordance with the manufacturer's instructions. Multi-layer application and appropriate detailing are important, particularly at wall-to-floor junctions and other vulnerable areas.\u003c\/p\u003e\n\u003cp\u003eAlways consult the current manufacturer's technical and safety data sheets before use.\u003c\/p\u003e\n\n\u003ch3\u003eFrequently Asked Questions\u003c\/h3\u003e\n\n\u003ch4\u003e1. What is Mapei IDROSILEX used for?\u003c\/h4\u003e\n\u003cp\u003eIDROSILEX is a liquid waterproofing admixture used to improve the water resistance of cement-based mortars. It is incorporated into renders and screeds for applications such as basements, garages, underground structures, swimming pools, reservoirs and canals.\u003c\/p\u003e\n\n\u003ch4\u003e2. How much IDROSILEX should I use?\u003c\/h4\u003e\n\u003cp\u003eThe manufacturer's recommended dosage for IDROSILEX Liquid is 3–5 kg per 100 kg of cement. The correct dosage depends on the mortar formulation and application requirements.\u003c\/p\u003e\n\n\u003ch4\u003e3. How do you mix IDROSILEX into mortar?\u003c\/h4\u003e\n\u003cp\u003eIDROSILEX Liquid should be diluted into the mixing water before preparing the cement-and-sand mortar. Follow the manufacturer's instructions for the correct dosage and preparation method.\u003c\/p\u003e\n\n\u003ch4\u003e4. Can IDROSILEX be used for basement waterproofing?\u003c\/h4\u003e\n\u003cp\u003eYes. IDROSILEX can be used to prepare waterproof cementitious renders and screeds for basements, garages and underground structures. The finished mortar forms part of a rigid waterproofing system and must be correctly applied and detailed.\u003c\/p\u003e\n\n\u003ch4\u003e5. Can IDROSILEX be used in swimming pools and water tanks?\u003c\/h4\u003e\n\u003cp\u003eYes. The manufacturer identifies waterproof rendering for swimming pools, canals and similar applications as suitable uses. The complete mortar system and construction details must be appropriate for the structure and intended service conditions.\u003c\/p\u003e\n\n\u003ch4\u003e6. Is IDROSILEX a flexible waterproofing membrane?\u003c\/h4\u003e\n\u003cp\u003eNo. IDROSILEX is a liquid admixture for cementitious mortars. It produces a rigid waterproofing mortar and should not be used as a substitute for a flexible waterproofing membrane where movement or deformation needs to be accommodated.\u003c\/p\u003e\n\n\u003ch3\u003eBuy Mapei IDROSILEX from Clever Shield\u003c\/h3\u003e\n\u003cp\u003eClever Shield supplies professional Mapei waterproofing products and construction materials throughout the UK.
