Natural stone is permeable to water and permeable. When it is soaked in rain, there will be water spots and it will not dry naturally. The iron molecules in the stone will appear yellow rust stains when they are soaked for a long time. It is a common stone disease to remove the powdered and bursting stone as soon as possible. A large area of ​​water stains will seriously affect the environmental effects of the wall surface, which is a headache for many property cleaning companies.
The best and easiest way is:
The R69 granite rust remover and the R96 marble rust remover are mixed and attached to the water molecules inside the stone.
The specific sample test steps are as follows :
First, bring plastic gloves, pour R69 and R96 into a clean paper cup in a standard ratio of 1:1;
Second, cover 4-6 layers of clean paper towels on the water surface;
Third, the mixture should be carefully poured onto the surface of the paper towel to fully soak and not flow out, and the effect of the sample will be more obvious;
Fourth, tear a small piece of plastic bag and cover it tightly to avoid volatilization of the drug;
Fifth, the corners are pasted with the textured paper for 4 weeks, and the ground is removed after 6-8 hours.
Contrast effect before and after operation
For severe stains, you need to repeat the operation 2-3 times, and some need to be baked.
When working in large areas, it can be adhered using a packaging film.
For the penetration of stone oil traces, there is currently no very effective remover on the market.
All removers will more or less damage the stone surface, and the repair labor is strong. Therefore, the best way is to prevent problems before they happen. It is very important to make stone surface waterproof protection in advance.
