Concrete Crack Repair Agent

Concrete Crack Repair Agent

JTB-4000 Concrete Crack Repair Agent is a two-component, milky white polymer water-based slurry formulated with graphene and high-penetration nanomaterials. It will not delaminate or crack when applied to rough concrete edges, making it a good solution for fast, invisible crack repair.

Product Features

• High bonding strength
• Acid & alkali resistant
• Aging resistant
• Reliable weather resistance
• Eco-friendly & non-toxic

Applications Scenarios

• Waterproofing & crack repair for new & old concrete surfaces, including shrinkage & pattern cracks;
• Crack repair for terrazzo & quartz flooring;
• Waterproofing, anti-seepage & crack repair for concrete, stone & structural elements; repair of concrete/PC components and masonry surfaces;
• Crack repair & renovation for concrete pavements, roofs; docks, ramps, parking lots, warehouses, industrial floors, highways, bridges, sidewalks, curbs

Construction Craft

• Surface preparation: Remove all loose dust, crushed stones, grease and other debris from the cracks in the base. Use clean water or a high-pressure water gun to clean the cracks thoroughly.
• Apply Concrete crack repair agent: Use a brush or roller to evenly apply the original liquid of JTB-4000 Concrete Crack Repair Agent to the crack area. Apply it back and forth evenly for 2 to 3 times. For fine and dense turtle cracks, you can apply it in a spread manner. After application, let it stand for 5 to 10 minutes to allow the Jintongbao concrete crack repair agent to be absorbed and penetrate.
• Grouting: Mix the color difference with black and white cement. After adjusting the color of the cement, mix the cement and JTB-4000 Concrete Crack Repair Agent in a 1:1 ratio to form a cement slurry. After mixing, use a scraper to apply and press the cement slurry into the crack, repeatedly pressing it tightly. Be sure to apply force when pressing. You can also make appropriate grooves according to the on-site conditions, fill the cement slurry into the grooves, smooth the surface, about 1 to 2mm higher than the horizontal level, and finally smooth and finish the surface. After it has completely solidified, gently sand it with sandpaper or a wire brush to achieve a seamless repair.
