The formation of puddles must be avoided. <br />After the coating has hardened, keep the surface damp for ≥ 24 hours. <br />Protect the fresh coating from rain, wind, frost and direct sunlight. <br />A load-bearing substrate is a precondition for a long-lasting bond between the substrate and coating system. Less adhesive and bonddamaging substances must be completely removed. High-pressure water jetting (> 400 bar; < 2000 bar) and jets with fixed blasting agents <br />are suitable measures. The last application step must be cleaning with pressure water jetting. <br />In rooms with high humidity and/or insufficient ventilation (e.g. water containers), dropping below the dew point (condensation formation) <br />may occur on the surface. This must be avoided by taking suitable measures such as by using condensation dryers. Direct heating or <br />uncontrolled blowing warm air is not permitted. <br />In the service water tanks, temperatures around +10 °C to +15 °C are usually expected. In order to ensure complete hydration of the <br />cement, the coating is kept damp for a sufficiently long period (constant relative humidity of > 80%) and protected against drying. 7 days are <br />generally sufficient for this. <br />Do not add water or new mortar to existing AQUAFIN®-1K-PLUS mortar that has already set in order to make it workable again. (Risk of <br />inadequate strength development) <br />For substrates that are subsequently prone to cracking, use AQUAFIN®-RS300, AQUAFIN®-RB400 or AQUAFIN®-2K/M-PLUS depending <br />on the application.</p> <p>Observe applicable safety data sheet! <br />Explanations <br />Conformity / Declaration / Verification</p> <p>The rights of the buyer with regard to the quality of our materials are based on our terms and conditions of sale and delivery.
