What Building Materials Should Be Avoided in Humid Areas?

Environments with high humidity levels such as coastal areas, mountains, or areas with high rainfall require special attention in the selection of building materials. Mistakes in choosing materials can cause faster damage, reduce the life of the building, and increase maintenance costs.

Here are some types of building materials that should be avoided, or used with extra consideration in humid areas:

1. Wood Without Special Treatment
Wood that is not coated with anti-termite and anti-fungal will quickly rot, become moldy, and porous if exposed to continuous humidity. If you still want to use wood, choose wood that has been preserved and coated with a protective material.

2. Regular Interior Paint
Regular wall paint is not strong enough to prevent the growth of mold or moisture stains. It is better to use special anti-moisture or anti-fungal paint, especially in bathrooms, kitchens, or rooms without maximum ventilation.

3. Ceiling from Regular Plywood
Conventional plywood is very absorbent and easily warped or damaged in humid conditions. Use alternatives such as PVC or waterproof gypsum which are more suitable for these areas.

4. Cement with the Wrong Mixture
A cement mixture that contains too much sand or water can reduce its strength and resistance to moisture. Make sure the mixture is according to the standard so that the casting results are denser and resistant to seepage.

5. Metal Without Anti-Rust Coating
Materials such as iron or steel that are not coated with anti-rust paint or galvanized will quickly corrode if exposed to high humidity. It is better to use galvanized iron, stainless steel, or do regular coating.

Choose the Right Material, Buildings Are More Durable
Choosing building materials that are suitable for environmental conditions is the main key to keeping the structure strong and requiring minimal maintenance. PT Intisumber Bajasakti provides various quality materials, including products that are suitable for humid areas such as galvanized iron, high-quality cement, and high-quality paint.
