When renovating an old bathroom, it is recommended to do these 4 things!

Renovating an old bathroom is crucial, and when it comes to remodeling, the first thing to consider is effective waterproofing. Since the old bathroom needs to be completely demolished and renovated with the original decoration, it is recommended to completely dismantle the old structure during this process, and then proceed with waterproofing treatment to ensure that the renovation effect is more lasting.

The following are specific step-by-step suggestions for bathroom waterproofing:

Complete demolition: At the beginning of the renovation, the bathroom wall and floor tiles are completely removed, including the cement mortar in the tile paving layer, down to the original plastering of the floor and walls.

Wall and floor repair: It is recommended to use waterproof mortar to repair walls damaged by gouging. If conditions permit, consider a comprehensive coating of the entire wall and floor.

Waterproof coating: After the repair is completed, apply the waterproof coating. Make sure to follow the formal procedures, first carry out local waterproofing, and then proceed to the overall waterproofing treatment.

Closed water test: Conduct a closed water test 3 to 5 days after the waterproofing is completed. This is an indispensable step. Only after passing the qualification can you proceed with the next step of decoration work.

Friendly reminder:

On demolished walls, carefully inspect and remove any hollow or cracked sections, then repair them with waterproof mortar.

When choosing waterproof materials, it is recommended to use the currently more common polymer cement waterproof coating. This material is easy to construct and has good waterproofing effect.

When performing a closed water test, it is recommended to wait at least 72 hours before conducting the inspection. Focus on checking whether there are leaks in the ceiling of the downstairs bathroom, and also check whether there are leaks on the outside of the bathroom wall roots.
