Waterproofing paints are essential in protecting the walls and floors of the basement and garage from damage due to water or moisture. There are several types of waterproofing paints available with different degrees of durability and with varying prices to suit different jobs. Waterproofing paints may also contain material which can be hazardous so precautions should be taken when applying them on the surfaces and the instructions by the manufacturer should be followed carefully.
The following are the type of waterproofing paint available.
• Masonry paint: this type of waterproofing paint is made through ceramic material and latex. It can adhere to hard surfaces like brick and cement and can be used around the house. The contents of the paint prevent the absorption of water and other liquids. Masonry paint can also resist mildew and the surfaces painted with it can be easily cleaned with soap and water. Many manufacturers of this type of waterproofing paint give extensive warranties.
• Epoxy paint: this paint is durable and water resistant and is used for waterproofing the floors of the garage or basement. This paint contains a type of resin called epoxy and this creates a rapidly hardening compound during application. Epoxy paint can adhere to metal, stone, concrete and cement. Epoxy paints are quite expensive but the water based variety is more economical. It can be used for different surfaces in the house as a waterproofing paint.
• Acrolein Elasticized Paint: this form of waterproofing paint is used on surfaces made of concrete. This compound prevents the growth of mildew, mold and bacteria caused by moisture. Acrolein is rather toxic and can cause an irritation to the lungs and throat and also damage the skin when it comes in contact with this substance. The toxicity of Acrolein is reduced when it is combined with acrylic paints which form a substance suitable for waterproofing. This form of waterproofing paint is manufactured mainly in China.
The appearance of the walls of basements can be greatly improved with the application of waterproofing paints. These are also protected from moisture, mold and mildew. Before applying the waterproofing paint the walls should be scrubbed clean of old paint and dirt. Any cracks and holes in the surface should be patched and smoothened. Protective eye goggles and safety masks should be worn along with protective clothing when painting the walls with waterproofing paints.
Any existing mildew should be removed with a mildew removing solution, to prevent the paint from bubbling. The walls and the room should be completely dry before the application of waterproofing paints.
A waterproofing primer should be applied on the surface to be painted. If necessary, two coats can be given. The waterproofing paint can be applied after the coats of primer dry. A paint roller can be used on smooth surfaces like finished concrete to apply an even coat of paint. In the case of painting a rough surface like masonry, a large brush would be more appropriate for the job.
The painted surface should be smooth and another coat can be applied after a few days if there are signs of seepage. Waterproofing paints are most essential to prevent moisture from seeping into the walls and floors of basements.
