Disadvantages of Incorrect Application of Concrete Sealers

Concrete sealers may stop working for several reasons, including poor application, inadequate surface preparation, product incompatibilities, adverse environmental factors, and aging. Several typical problems can develop from the improper application of concrete sealers.

1. Thick application can cause bubbles

Rolling over a thick layer of concrete sealer can cause bubbles to form because the motion of the roller forces any trapped air between the sealer and the surface below to the surface. The bubbles can provide an uneven and ugly appearance on the surface and jeopardize the sealer’s capacity to shield the concrete from moisture and other impurities, which is a problem when applying concrete sealers.

2. Trapped humidity can cause discoloration

Concrete sealer might get discolored due to trapped humidity because it can become milky or hazy. This occurs because the sealer components may react with the humidity and impede appropriate curing, resulting in discoloration. Additionally, efflorescence, a white, powdery substance that develops on the surface of the concrete, might result from trapped humidity. This could make the discoloration and other aesthetic problems worse. Therefore, ensuring adequate concrete sealer application and curing is crucial to avoid concerns with moisture and trapped humidity.

3. The sealer can peel over under unfavorable conditions

Concrete sealers can lose their ability to adhere to concrete surfaces when misapplied or under unfavorable circumstances, such as excessive humidity or wetness. The sealer may peel or delaminate due to this weakening of the connection, leaving the surface vulnerable to harm from the elements, human traffic, or other environmental variables. Additionally, the sealer may only adhere effectively and peel over time if the surface is adequately prepared before application, such as by being well-cleaned and clear of dirt.

4. Fast drying of sealers creates fissures or lines

When applying concrete sealers, sealers that dry quickly might leave fissures or lines on the surface of the concrete as a result of the solvent’s quick evaporation causing the sealer to shrink and pull apart. Particularly in hot, dry climates or those with insufficient ventilation, this can occur. The lines or cracks may reduce the sealer’s efficacy and diminish the appeal of the concrete surface. To avoid these drawbacks, it is crucial to use a sealer that dries slowly or utilize application methods that prevent rapid drying.
