Concrete paints or surfaces sealers cannot withstand water pressure, peel under attack by chemicals from the concrete, or blister due to efflorescence. RadonSeal permanently stops water seepage even against hydrostatic pressure. Exterior coatings deteriorate. Excessive dampness results in condensation. Floor covering or finishing the basement traps moisture.
Humidity promotes molds, mildew, and a musty odor, which circulate through the building.
Concrete paints or surface sealers are porous or crack and blister, and cannot stop water vapor. Power-hungry dehumidifiers pull in more moisture through the concrete, speeding up its deterioration. RadonSeal reduces vapor transmission and dampness in the house. Water also carries dissolved radon indoors. It saves hundreds of dollars on the cost of a fan radon mitigation system and even more on annual operation and maintenance.
