Exterior wall coating: preliminary work can not be ignored

In order to ensure the painting effect of exterior wall coatings, the preparatory work can not be ignored. This paper will introduce the preparation and matters needing attention in the process of exterior wall coating construction to help you build a perfect exterior wall.

♀? First stage preparation

Before painting, we need to carefully maintain the external wall to ensure that the wall is smooth and flawless, and avoid potholes, bumps and cracks. Only in this way can we create a perfect external wall for you.

Importance of primer

Before we start painting, we will paint the outer wall with primer. Primer has super bonding ability, which can seal the alkalinity of the wall and ensure that the paint can be firmly bonded to the wall. In addition, the primer can also make the ash layer and putty bottom perfectly integrated, significantly improving the waterproof performance of the external wall. At the same time, the primer can also save the amount of paint and make the brushing effect more uniform and beautiful.

Brushing technique

In the process of construction, we suggest using short wool roller for painting to ensure that every detail is carefully treated to avoid sagging and paint leakage. Before painting the top coat, we will carefully check whether the primer is missing and whether the wall is polluted. Before everything goes smoothly, we will not start the construction of the first coat of paint, and ensure that the top coat is uniform and in the same direction.
