How to deal with the splash marks of leaking houses?

If the house leaks and splashes with peeling, it needs to be eradicated, repaired and coated with interface agent, and then putty and paint; If there is no peeling phenomenon, you can brush the interface agent after cleaning the floating dust, then scrape the putty and brush the paint.

Leaked splash marks, with some dirty colors affected by rain, have strong permeability. If it is not closed, it will ooze from the scraped putty layer and latex paint surface, which will affect the decoration effect. Interfacial agent can seal the base, prevent infiltration and strengthen the bonding between the inner and outer layers. After repairing or cleaning the stripped top surface of the wall, brush the interface agent to avoid the color penetration of leakage marks and enhance the adhesion of the putty in the later stage, then scrape the putty layer, polish it and paint it.

Suggestion: No matter whether there is rain leakage or old house renovation, the top surface of the wall should be cleaned and repaired, and the interface agent should be brushed to ensure that the surface does not change color.
