Why did my concrete sealer turned white?

Trapped moisture under the sealer is the most common reason that the sealer has turned white. This happens to sealers that are not breathable or over applied. The sun will raise the moisture out of the concrete or bricks but the water cannot escape as it is trapped under the sealer.

Keep Concrete Moist for Maximum Strength. QUESTION: I've been told that new concrete should be kept moist for at least three days while curing.

Can you seal old concrete?

A: Yes! Old concrete can be sealed for the first time or resealed if it has been previously sealed with a concrete sealer. You want to make sure all mold, mildew, efflorescence, rust, grease and oil are removed from the concrete before sealing as you do not want to seal these elements into the concrete.

The acid washing of concrete is a requirement after the concrete has cured sufficiently, in order to remove surface efflorescence and to open the pores before sealing. This will help the sealer to penetrate and result in a superior bond between the sealer and the surface.

Is sealing concrete necessary?

While concrete is strong and durable, it is a fallacy to believe that it needs no protection. In fact, without proper protection, concrete will not even be that strong or that durable. The most cost effective way to protect concrete is to use a concrete sealer as soon as the concrete has finished curing.

Does sealer darken concrete?

Sealers, particularly solvent-based sealers, will darken concrete. If unevenly applied, it will create light areas where there is less sealer, and darker areas where there's more. If applied by sprayer, it may appear like “stripes”. Uneven roller application may leave darkened roller marks.

Do driveway sealers need two coats?

In some cases, a residential driveway will only need one coat of sealant. However, if the asphalt sealcoating has never been sealed before, it may take a second coat to give it the rich, deep finish that most homeowners prefer. Vehicles need to be kept away from the area until the sealant has dried thoroughly.
