[BRD classroom] construction process of flexible clay tiles(Ⅳ)

flexible clay tiles is a new type of building decoration material, light weight, thin texture, crack resistance and frost resistance. It is more and more widely used in decoration construction. Today, we will introduce the construction process of flexible clay tiles exterior wall brick,we will talk about the fourth step.

Cleaning
No matter in the process of bonding or pointing, attention should be paid not to contaminate the board surface with adhesive or sealant. If it is not carefully touched on the board surface, do not wipe wet before the contaminated slurry is dry, so the scratch marks left will pollute the board surface in a larger area and it is not easy to clean up.
The correct way to deal with it is: after the initial setting, remove it with a tool such as a gray knife, and then wipe it with dry towel or sponge at the contaminated place.

If the whole scaffold is removed after the construction is completed, if there is a whole dirt phenomenon, it is possible to use vehicle foam cleanser and weak dilute oxalic acid solution similar to the clean tile to clean the whole body. Do not use hard material such as steel ball to avoid scratching flexible clay tiles. No matter what kind of cleaning treatment is done, local small sample experiment should be done in advance, and large-scale operation can be carried out after the effect is approved.
