The room was damp and moldy, and the wallpaper on the wall was covered with insects. What should I do?

The root cause of mildew is: 1, the waterproof of the external wall is not done well, and there is water seepage. 2, indoor humidity, water infiltration putty layer. 3. Improper selection of putty, ordinary putty is not waterproof and easy to mold.

If the external wall is leaking and moldy, the solution: please waterproof the external wall again, otherwise the problem will not be solved from the inside.

If it is damp and moldy indoors, the treatment method: remove the original putty layer, level the external wall with waterproof putty or inorganic primer, and then make a top coat. It is best to coat the top coat with a stain-resistant treatment, which can effectively isolate the wall surface from the indoor environment and never get wet.

Remove the putty first, and then make waterproof putty again. Apply a primer and a second coat of paint. Then use Xuanhe Jun glaze antifouling paint, brush it on the old wall with a brush or roller, and brush it again after the first coating is dried for half an hour. The surface antifouling layer is ready.

Material: a bucket of Xuanhe Jun glaze stain-resistant treasure.

Tool: brush or bucket.

Efficacy: Pen, gel pen, pencil and ink can be scrubbed without trace.

Quality inspection: inorganic mineral coating, 0 formaldehyde and no glue, environmental protection and health.

After the wall painting is completed, there will be no more mildew.
