For some old tarpaulins, many people are reluctant to throw them away, but if they continue to use them, they are afraid that they will be damaged, so how can they be used for a longer time? We can learn some relevant knowledge from tarpaulin manufacturers. In fact, a better way is to coat the old tarp. First, clean the soil on both sides of the tarp and spread it on the mat or worn-out tarp to avoid soiling. Then put the prepared material into a basin or a small bucket, and evenly pour it on the tarp. Another person uses a broom to sweep around and brush with a floor brush to put the material into the tarpaulin weave. After the tarpaulin is completely brushed, fold the tarpaulin half a meter thick. After folding it up, people use their feet to make it even and unspoiled. Then fully open it, and after drying it for a while, brush it again. It should be noted that for the old tarp, the coating must be brushed twice. Although the materials used for the two brushing may be different, the brushing method is the same.
