Striking a Balance between the Temperature
As the extreme of anything is harmful, same applies for the application process as well. Too high or too low temperature can cause various kinds of problems and hence, may ruin the whole purpose of the concrete sealer.
A very low temperature leads to a very high possibility of the failure of the concrete sealers. It can cause the following damages to the concrete sealer:
* It might not get completely dried,
* This will lead to the weakening of the concrete sealer coating,
* The sealer will be, hence, unable to form a strong protective coating.
On the other hand, a very high temperature poses the problem of the sealant drying up too early which leads to the formation of the blisters on the surface of the concrete wall. This happens because the air and gas get entrapped between the constituents. Also, the high temperature hinders the process of flattening the sealant since it causes the sealant to stick to the roller. Therefore the sealant does not get evenly applied to the surface.
The optimum temperature for applying the concrete sealer is 50 - 90 degree Fahrenheit.
Preventing the Blushing effect
Blushing is another common problem faced by people while applying coatings to their walls or floors. It refers to the fuzzy blotches that appear below the surface where it has been applied.

Also, the concrete sealer should be applied as per the specialist’s advice who recommends it to be applied in even manner.

Prolonged exposure to such environment can lead to the sealant wearing off from the concrete. As a preventive measure to this problem, the following procedure should be followed:
A penetrating sealant, which can permeate into the pores of concrete should be applied as the first coating on the concrete wall. Following this, the surface sealer should be applied on the concrete.
