Plastering additive Mortar Admixture

This is a plastering additive special for plastering. Performance 1 Prevent hollowing and peeling: The inorganic activate the activity of cement, which make the cement exert abundant effect of gelatinate material. The inorganic macromolecule polymeric substance including in the product combine these particles, so increase the adhensive power that paste the mortar on the substrate, prevent hollowing and cracking . Also reduce the dust, increase the work efficiency, save energy. 2 Anti permeability and anti freezing: the tiny air bladder barricade the vein of mortar ,prevent the water seeping , be good to increase the performance of anti-permeability and anti freezing because of the micro air-entraining agent 3 Anti cracking: change the performance of crisp and stiffness of the basic cement mortar to be with enough Intensity,Flexibility and Tension. The tension would appeal some chemistry contraction stress and outside force, so the possibility of impart cracks would reduce obviously.

Use-method 1 Quantity: 0.2%-0.4% of the cements quantity, we will supply one standard 100g measure container. Use the machinery to agitate. 2 Vertical or Horizontal agitating process: power + part sand + mortar additive + water(agitate) + cement + the surplus sand + water + 3-5mins agitating. 3 Rolling agitating process: put the mortar in the cements and sand, then agitate 1min without water, then add enough water and agitate 3-5mins. 4 The agent should dissolve in the water first then put in the mortar if the workers to agitate. Reduce 20% water after mix the mortar agent. Scope of using 1 Store in the dry and Ventilation place to prevent being wet. 2 Substrate: there are many concave or Convex parts on the blocks, concrete and air-entrainment concrete substrates, so you must make them leveling with cement mortar with 1:3 at first. if the surface is too smooth to use mortar, should make it rough or use the interface agent, of course the dirty points or paint must be cleaned first. 3 Watering to keep wet: water the wall or block 1day earlier, the water must be seep in the blocks 10-20mm .If plastering in the summer or autumn, remember to water more, to prevent being dry, of course in the rainy days, should water less. The direction of watering should be from left to right, from up to down, and control the water force small to ensure the quality . Water the surface of the concrete and air-entraining concrete earlier, control the water force and humidity. 4 Conserve well. If the temperature is over23°C, water the wall to conserve after painting.
