Polymer repair mortar definition mix ratio use method Polymer repair mortar is organic polymer modified synthetic emulsion, a variety of additives and hard dry powder in a certain proportion. It has good workability, non-toxic and environmental protection, good adaptability to old concrete base, strong adhesion, good impermeability and protection for steel bars.
use
1. For the repair of reinforced concrete or cracked building surfaces, panels, load-bearing columns, beams, etc. in industrial and civil facilities, exterior plastering of wet industrial and civil buildings.
2. It is used for repairing defects such as concrete honeycombs and holes, repairing thin layers of damaged concrete floors, and making overall repairing protective surfaces on the surface of concrete, masonry or steel structures.
3. For the repair of industrial and civil buildings that have been damaged and cannot meet the design requirements. It is especially suitable for the repair of floor slabs, panels and open sheet structures.
4. Maintenance works for underground pipelines, power plant water towers, chimneys, chemical plant structures and various plant buildings with corrosive gases.
5. This product is a polymer mortar used in the “Wire Rope Polymer Mortar Reinforcement Methodâ€.
6. This product is a polymer mortar used for “road and bridge repair and leveling reinforcementâ€.
Implementation standard GB50212-2002
Grassroots processing:
1. The surface of the base layer requires clean, dust-free, oil-free, and non-chemically corrosive medium residues. The surface of the porous material should be wetted with water in advance, and the surface of the steel base should be cleaned of rust.
2. If there is a leak, it must be treated with 901 fast plugging agent. It is best to keep the base surface moist until no water is available to achieve better construction results.
Material preparation:
1. Pour the glue into the bucket first, then slowly add the powder according to the ratio of glue: powder = 1:4, stir until evenly agglomerated.
2, can be mechanically stirred or artificially mixed, the prepared glue should be used within 2-3h.
Construction and maintenance:
1. When using EC2000 polymer repair mortar as the overall surface layer, the thickness should not be less than 3mm. When the construction area is large, the construction joints or shards should be staggered. Each area should not exceed 10-15m2, depending on the site environment. The gap between the seams or the shards should not be less than 24h.
2. When making the integral surface layer on the façade of concrete or masonry structure and the surface of steel structure, it should be carried out twice, and the interval should not be less than 24h. When the last time is applied, it should be smoothed once and not repeatedly.
Precautions
1. The ambient temperature of the product construction is 10-30 °C, which should not be lower than 5 °C. The raw materials should not be contaminated by moisture, rain, sun and debris.
2. This product should not be used in rainy or frozen conditions. If it is necessary to work in winter, the necessary antifreeze measures should be taken. This product should be used with the mix, not too much mixing at a time, and each mix should be used up within 2-3h.
