Can you seal the flaking concrete?

A good quality sealant designed for use on outdoor concrete will help minimize water saturation and protect against salt damage. The second thing you can do is apply a water-repellent sealant. Water-repellent sealants are a great solution for concrete peeling because they cause water and other liquids to peel off the surface. They reduce water absorption by up to 95%, preventing water from freezing inside the pores.

Silicate sealants can be used in combination with water-repellent sealants if you feel that you need an increase in strength and a decrease in water absorption. If you apply both sealants, you would first apply a silicate densifier followed by a silane siloxane water repellent sealant 5 to 7 days later. Sealing is the best way to prevent it from flaking due to moisture. For new concrete, apply a penetrating waterproofing sealant 28 days after the concrete is laid and every few years thereafter.

If the surface of the driveway has peeling concrete, then most likely the cause is an installation error. Common mistakes include adding too much water to the mix to facilitate pouring; spraying the concrete surface with water to prolong the finishing time; and not curing the concrete properly after installation. shelling concrete on a horizontal surface such as an entrance or sidewalk is not only an aesthetic problem, but also a safety hazard. Chipping on a concrete driveway or sidewalk may require a more comprehensive solution to ensure it doesn't return.

The most common method to repair flaking on horizontal surfaces is to coat and seal the surface with a resurfacing solution. The advantage of using this method is that it not only repairs peeling concrete, but also prevents flaking problems from reappearing. If the chips penetrate less than a third of the depth of the concrete, a patch or repair can correct the problems. Chipping occurs on external slabs when water trapped in concrete goes through multiple freezes and thaws.

If flaking has already occurred, V-SEAL can and should be applied to keep the concrete under control and greatly help prevent further damage. Deicing chemicals only aggravate already stressed concrete by allowing more water to migrate into concrete, increasing the size and depth of husking failures when freezing occurs. Smaller areas with just a few chips can be repaired without re-paving the entire area, although patches may be more noticeable. All concrete can develop cracks and flaking is inevitable, especially in colder climates and as concrete ages.

Chipping is the peeling or detachment of small particles of cement paste from the portion close to the surface of the finished slab. Those are the symptoms, but the peeling of concrete is a bit more complex than the appearance at the surface level. The symptoms of concrete peeling are flaking, chipping, and large pieces that you see missing from the concrete surface, exposing the aggregate of coarse, rocky concrete. To prevent flaking, you need high-quality sealing and curing that can allow concrete to breathe while protecting it, especially during that critical first year.

In recent years, complaints of chipping (flaking) of exterior concrete surfaces have been increasing. Over the course of a winter, or over the years, as internal pressure increases and decreases, the surface layer of concrete is stressed, which leads to flaking. When you use V-SEAL, you can be sure that you are using a deep penetration HI-TECH formula that will enter and protect during those critical years and stay for many years to come. .
