A common effect of applying sealant to a pattern imprinted concrete driveway in the winter is something that in the industry, we call blooming. This can cause alarm to a customer who witnesses it, in fact it is one of the most common telephone calls we receive, with customers believing that their driveways our ruined beyond repair. It is understandable that seeing your investment in this state can be worrying, but it need not be. The solution is simple.
Blooming is caused by a ‘reaction’ of the sealant to moisture, causing the surface sealant (not the concrete) to turn cloudy and in some instances white. Although we take every caution to eradicate moisture from the concrete, it is often difficult, particularly in the winter months, to prevent concrete from retaining this moisture. However even with blooming present you should still be assured that the pattern imprinted concrete underneath is protected.
Once the climate reaches a suitable temperature, we will do what we call a reseal. This involves breaking down the existing sealant with thinners, thus eradicating the blooming, before resealing the driveway to the way it looked before.
These pictures are from a driveway we installed at a home in Farnworth in December, which due to the winter conditions developed some blooming. We recently resealed the concrete so it now looks as good as new.
