What is permeable pavement sealant
Five advantages of Bangwei permeable concrete surface protective agent: 1. It has better brightening and strengthening effect than traditional pavement protective agent
2、 It can meet the requirements of improving the mechanical properties, service functions and service life of the structure
3、 It can protect the performance of permeable floor and realize the effect that the surface layer of permeable floor can not shed grains for a long time
4、 It has good use function and can better improve the service life of the floor.
5、 The utility model has the functions of keeping the color of the color permeable floor, preventing fading, preventing carbonization, etc.
BW301 pervious concrete covering agent - the application scope is applicable to the sealing protection of pervious floor, colored pavement, concrete components and other covering materials. With yellowing resistance and weather resistance, it is beautiful and durable. BW301 permeable concrete covering agent - instructions for use 1) Clean the surface dust and keep the surface dry and free of oil stains; 2) After the material is uncovered, it can be used after mixing evenly, roller coating or spraying evenly; 4) It can be put into use 12 hours after completion, and the longer the time, the higher the hardness.
2 High bearing capacity. The floor surface strength is generally the bearing capacity of permeable bricks after the use of permeable floor surface protective agent identified by the national testing authority.
Color sealant for permeable concrete pavement

4、 It has good use function and can better improve the service life of the floor.
5、 The utility model has the functions of keeping the color of the color permeable floor, preventing fading, preventing carbonization, etc.
Instructions for use: permeable floor protective agent can be directly sprayed on permeable brick, permeable concrete, permeable pavement, permeable surface layer, and airless spraying machine 0.2 kg/m2.
The type of aggregate can greatly affect the surface abrasion resistance of pervious concrete. Geadicke et al. studied the abrasion resistance, porosity and compressive strength of permeable concrete produced with original coarse aggregate and recycled coarse aggregate respectively, and found that the permeability of permeable concrete produced with recycled coarse aggregate was nearly 20% lower than that of permeable concrete produced with original coarse aggregate under the same porosity of test blocks, Compared with limestone fragments and recycled concrete aggregates, the surface abrasion resistance of pervious concrete mixed with pebbles also decreases by nearly 20% [9]. Kever et al. pointed out that using plastic mold curing and selecting soybean oil as curing film can increase the abrasion resistance of permeable concrete [23]. There are also studies on using recycled concrete aggregate and recycled concrete block aggregate to produce permeable concrete, For pervious concrete mixed with recycled concrete block aggregate, the surface abrasion resistance of pervious concrete will be improved only when the content is 20%. The researchers believe that although the performance of recycled aggregate is worse than that of natural aggregate, the surface of recycled aggregate is porous and rough, which can be well cemented when mixed with cement paste, thus increasing the strength and surface abrasion resistance of permeable concrete [24].
Permeable concrete protective agent is also called permeable concrete finish , concrete covering agent, permeable concrete sealing agent, divided into color and transparent. According to different materials, there are oily materials and water-based materials. According to the different ways of use, there are two components and one component. Bangwei Building Materials believes that, as a protective agent for outdoor pervious concrete, its weather resistance and UV resistance should be considered. The protective agent for pervious concrete itself is composed of resin and additives, and different resin properties vary greatly, especially for those with poor UV resistance and UV resistance. Over time, the protective agent will appear brittle and peeling on the surface Color fading, etc. Sealer
The two-component waterproof concrete protective agent generally refers to the double acrylic polyurethane sealant, which is composed of two components, one is resin, the other is curing agent. When used, it needs to weigh the weight in proportion, and then mix and use. The construction is more complicated. Bangwei Building Materials believes that this kind of pervious concrete protective agent has relatively high requirements for the performance of the curing agent, which requires strong UV resistance, no yellowing groups and other properties. At present, most of this kind of curing agent is imported materials, and the cost is very high. Several large domestic chemical enterprises also produce it, and the cost is similar to that of imported ones, but the performance is poor, Therefore, if there is a cheap dipropylene polyurethane sealant in the name of imported curing agent on the market, please keep your eyes open. The cost of water-based curing agent is also relatively high, about 80 to 90 yuan per kilogram. The relative cost will also be very high when applied to permeable concrete protective agent. At present, its economy and practicality are not too high. Concrete sealer
There are many kinds of single component permeable concrete protective agent, and its ultraviolet resistance should also be taken into consideration. Why should we consider this aspect? Bangwei Building Materials believes that because resin materials are used outdoors, if there is no strong UV resistance, the performance of the resin will decline over time, leading to various problems. Compared with materials such as dipropylene polyurethane, the cost of single component protective agent is lower, and the construction is also relatively simple. This is a kind of composite synthetic resin, which is composed of different monomers. Each monomer has different properties and costs. The cost of good ultraviolet resistance will also be higher. Users need to compare more when choosing this type of product, Avoid quality problems.
