DESCRIPTION TEKWELD is a synthetic resin in form of aqueous
TECHNICAL DATA SHEET Version march 2013 ADHERENCE AND BONDING RESIN FOR MORTAR DESCRIPTION TEKWELD is a synthetic resin in form of aqueous dispersion, stable in alkaline environment, it is used specially in order to be added to the mixing water for concrete mortar, cement mortars or plaster mortars. PROPERTIES TEKWELD - Improves the adhesion between the old and new concrete. - Improves waterproofing. - Improves the tensile and flexion strength. - Reduces cracking. - Reduces shrinkage. - Wear strength. USE - Used in the preparation of adhesive components for concrete bonding. - Filling of cracking. - Coating of the casing. - Repair and refilling of concrete substrates.

APPLICATION PROCEDURE The adhesive grouts, as mortars, shall be applied on a clean and sound substrate. They must be free from laitance, loose parts, traces of grease, oil, rust…. In hot weather, humidify slightly the substrate. ADHESIVE GROUT Prepare the TEKWELD + WATER solution , then under stirring add the cement until to obtain a homogenous grout. MICRO-CONCRETE FOR BONDING After the mixture of the aggregates and the cement , as specified in the given dosages , add the TEKWELD + WATER solution until to obtain the required consistency.
