Before construction, waterproof should be prepared, level the wall, then use adhesive mortar to stick the foam board on the wall, and level it. Fix it on the wall with insulation nail, then use the foam surface mortar board to cover the bottom layer, embed sideways the alkali-resistant fiberglass mesh in the bottom of the mortar , then coat another layer of plaster mortar, and finally cast a flexible putty, to embark on surface treatment.
1. Wall should be kept clean and dry. 2. Paste mesh at cracks and press tightly. 3. Confirm the gap has been covered by mesh, then cut useless mesh with a knife, the last step is to brush on mortar. 4. Leave it dry alone, then polish lightly. 5. Fill it with enough coat to make the surface smooth. 6. Remove extra mesh. Then, pay attention to that all the cracks have been properly repaired, decorate around with composite material to make it clean as new.
Firstly : We must maintain a neatness of wall, as well as dryness before construction, if wet, then, we must wait for the walls to dry thoroughly before construction. Second: Stick adhesive tape on fissure of walls, and press them tightly after sticking up. Pay attention while sticking that don't overexert. Third: Make sure again whether cracks have been covered by the tape, if no, then bring it down and restick it. This part is very important, then cut off extra tape , after cutting, buy some mortar of high quality. Leave the mortar dry itself, and then polish it, so as to make the wall become smooth, if not smooth, which demonstrate that it is filled not enough, then refill, polish once again. after all the walls become smooth, check again whether there is missing tape forgotten to cut. After all the cracks have been repaired and then decorate it with glass fiber mesh around cracks, the wall will be like new again.
