01

Recognize symptoms

A bulge is a local bulge formed after the coating film loses its adhesion; as it continues to develop, the coating film will crack, peel, and detach from the base layer or the previous layer of coating.

02

Find the cause

  1. The wall contains water or continues to leak

    Exterior walls, pipes, wet areas or condensation continuously add moisture to the wall.

  2. The base layer does not meet the construction conditions

    Insufficient drying, or there is powder, dust, oil and old glue on the surface.

  3. Incompatibility between coatings

    Improper combination of oil-based and water-based systems, missing primer, or the previous coat has not dried.

03

Create a repair path

  1. 1
    Find the water source first

    Check for leaks, moisture return, condensation and construction water. Do not cover directly if you are not sure of the cause.

  2. 2
    Clear failed layer

    Remove bulges and loose coating until the edges are firm and the base is stable.

  3. 3
    Allow base layer to dry and re-treat

    Complete cleaning, repair, reinforcement or matching primer according to the condition of the base layer.

  4. 4
    Make a system model

    Confirm adhesion, color and drying results before proceeding with large-area construction.
