Waterproof Paint for Interior Walls – When moisture seep into the interior walls of your home, it can cause mold, mildew, cracking, or even structural damage such as moving the wall. Moisture often affects the interior walls of basements, as groundwater and rain can seep into small openings in concrete foundations.
In addition, hydrostatic pressure, or pressure of resting fluids, can accumulate around the perimeters of the interior walls of the basement, which is what causes cracking and structural damage. Fortunately, there are several strategies that you can use to waterproof the interior walls.
Sealants are specialty chemicals that can be applied to the interior walls of wood or masonry in the same way that a coat of paint would apply. However, unlike paint, a sealant fills the gaps and tiny pores of a material, making the material waterproof and less prone to flooding with water.
As the LookSmart House inspection stresses, while sealers are not effective in relieving hydrostatic pressure behind the interior walls of the basement, sealers may limit shredding, which is the deterioration of Concrete foundations due to excessive moisture.
Water Resistant Drywall
Due to the absorption capacity of the gypsum board, the coating with a sealant is not the best option for waterproofing. Also known as gypsum board, gypsum board consists of a plaster core surrounded by thick paper wrappers. When these packages get wet, they can transmit moisture to the plaster, which includes the integrity of a whole drywall panel.
If you are convinced to use drywall for interior walls in a moisture prone area, such as the basement, ask the builder recommend to use a green table. The green panel is a specialized type of gypsum board that features green packaging that is resistant to moisture. In addition, the gypsum core of the plate often has a wax or silicone coating, which protects the core from moisture.
The installation of a sump pump is an idea of inner wall sealing that is specifically adapted to basements. A sump pump uses a centralized sump, or, which “extracts” water from the interior walls and collects it through the natural force of gravity. A pump then discharges the water from your home and sends it out.
A French drain is a plumbing system that can be used in conjunction with a sump pump. The drain installation requires a 4 to 6-inch wide hammer or a canal along the inner perimeter of the basement walls. A perforated tube, slightly inclined towards the sump, rests in the hole.
Compared to the use of a single sump pump, a French drain helps guide the water away from the interior walls more easily, which increases the efficiency of the pump to waterproof the walls.
