Concrete sealing
Does concrete need to be sealed?
Poly-Lift ·
Yes, especially in a climate that freezes. Concrete is full of tiny holes and cracks where moisture from rain and snowmelt seeps in, weakening it and encouraging mold. Sealing keeps that water out, and in a place like Cache Valley it is worth resealing every year or two.
Whether you have a driveway or a patio, sealing your concrete is one of the simplest ways to make it last. Concrete has small holes and cracks in the surface, and when moisture from rain or melting snow seeps in it can weaken the concrete or even cause mold to form. A good seal locks that water out.
The main types of sealer
Not every sealer is the same. The three you will hear about most are:
- Acrylic resin-based sealers, the least expensive option, good for basic protection and appearance
- Epoxy and polyurethane sealers, which last longer and stand up to more wear
- Penetrating sealers, which soak in for the deepest protection
What happens if you do not seal concrete?
Unsealed concrete takes on water, and in our winters that water freezes and expands inside the slab. Over repeated freeze-thaw cycles the surface spalls, flakes, and cracks, and the color fades. In a climate with big temperature swings like Cache Valley, resealing every year or two keeps concrete looking new and holding up.
What to expect during a seal
We start by cleaning the concrete and clearing the seams, then grout the cracks so water cannot creep underneath. After the grout dries we spray the sealant in smooth, even strokes and let it cure for about a day. When it is done, your driveway or patio is protected and looks great.
