When the customer asked for six-sided protection of the stone, six-sided protection was actually provided, and an oil-based protective agent was used for six-sided protection. After the six-sided protection, a problem arose. The construction workers reported that the stone and cement could not be bonded at all.
How to deal with problems after six-sided protection
If there is equipment such as hand grinding at the construction site, use the hand grinder to remove all the protective agent on the bottom surface that has been protected. It must be completely polished off. If it is not polished off, there will definitely be problems with the stone being hollow or still not sticking after installation.
If the above conditions are not met, there are stone processing factories, stone sandblasting factories or glass sandblasting factories near the construction site, which can sandblast the stone that has been protected from the bottom and blast off the protective layer. However, this cost is very high and may not be economical. Not allowed on.
If the quantity of stone is small, a manual hand grinder can be used to polish off the protective layer on the bottom surface. However, a construction site cannot have only dozens of square meters of stone. This method is only suitable for construction sites with a small amount of stone. Moreover, I used an angle grinder to polish the waterproofed back side because the angle grinder was too small and the waterproof layer could not be polished cleanly. There were still some areas where the cement was not bonded.
