I.Bathroom cabinetsHow to handle gaps?

1、The bathroom cabinet has developed cracks. Fill the cracks with paint and putty powder mixed together. If the painted surface is scratched but does not affect the underlying wood, use wax crayons or paint that matches the cabinet color.

2. Apply paint to the exposed surface of the cabinet to cover the underlying color, then apply a thin layer of clear nail polish.

3. If there are white stains on the bathroom cabinet, they can usually be removed by wiping with a cloth dampened with alcohol, cologne, or a solvent-based cleaner.

Two. How to handle the gaps on both sides of the bathroom cabinet.

If the gaps between the sides of the bathroom cabinets are large, you can purchase gap storage racks, which typically have a width of around 15cm. If the gaps between the sides of the bathroom cabinets are small, only 2-3cm, then you can refer to the following solutions:

1、Purchase wood planks approximately 2cm thick. Measure the length and depth of the gaps in your space. Then, insert the wood planks into the gaps. After applying the final coat of paint, you can complete the project. Although the gaps are 2-3cm wide, using 2cm thick wood planks may still leave some gaps. However, this is not a problem because bathroom cabinets also experience expansion and contraction due to temperature changes.

2. Purchase a trim molding with a width of no more than 3cm. Measure the length of the gap, and then attach or nail it to the cabinet and the walls on both sides, concealing the gap and creating a decorative and aesthetically pleasing trim. This eliminates the need for painting. Note that the side edges will not be perfectly straight due to the thickness of the trim.

3. If using wood strips for finishing, the surface coating should ideally match the color of the bathroom cabinet. Leave some gaps between the strips for easier maintenance or updates in the future.

4. If you are concerned about water seeping from the sides into the floor after application, you can ask the supplier if they offer trim or edge profiles to fill the gaps. Manufacturers often provide complementary products to match their materials, which eliminates concerns about color variations or waterproofing.
