Considering that the aerated concrete block partition wall technology adopted by your company at this stage is easy to empty and crack, we do not recommend direct putty-latex paint construction. It is suggested that Party A change the partition technology, or plaster after hanging glass fiber mesh, and plaster with anti-crack mortar for the second time after napping treatment; And paste cloth before scraping putty to meet the requirements of crack resistance. However, the sequential construction scheme will generate a large cost, and it is expected that Party A will make adjustments on the basis of the original contract price. (Just drive up the price and let Party A disagree. )

The second letter, exemption

After coordination and communication with Party A, the site failed to operate according to the construction technology proposed by us. Therefore, we can't guarantee that the latex paint on the surface of aerated concrete block partition will not crack within two years of normal use. Therefore, in case of hollowing and cracking during the period, our company will not be able to fulfill the warranty obligations. Please understand your company.
