Seal Garage Floor or Not?: Pros and Cons of Concrete Sealing

Sealing a concrete floor is something most professional contractors recommend highly. Although it seems just like an additional thing to do, it is more important than you think. Most homeowners are having two minds about considering concrete sealers so here is a brief guide to why you should give it a go, especially on garage floors:

  • A sealer, such as an epoxy flooring can help repel moisture and keep it on the surface. The garage floor is exposed to a lot of moisture, whether it is from driving in from the rain or spilling something on the floor. Now, bare concrete is very porous. Any amount of moisture gets easily absorbed and this could cause damage deep within the slab.
  • A sealer is stain-resistant. Because it seals off the pores, nothing gets past the surface. This means anything that could cause stains won’t be able to leave any colored pigments behind.
  • Sealed floors last longer. When a concrete slab is resistant to most damaging elements, its lifespan is extended and zero to minimal repairs are necessary.
  • Sealers enhance and maintain appearance. There are different types of concrete sealers. There are epoxy and polyaspartic that creates a seamless and appealing surface and there are clear ones that deepen colors and protects any design or pattern on the floor.


  • Sealers could be slippery. Most sealers dry with a shine and create a seamless layer. It can be pretty slippery especially when wet but there is a way to increase traction. Contractors recommend adding some sort of fine abrasives to the coating to create a non-skid surface.
  • A resealing is required every few years. It is quite unfortunate but sealers do fade, especially in high traffic areas. This is why it is highly recommended to have the sealer reapplied every two years to ensure that the floor is protected at all times.
  • Some sealers can be dangerous to humans, pets, and plants. Most sealers are solvent-based materials that contain harsh chemicals. These require safety gear to apply because it could be dangerous to touch or inhale. There are, however, safer types of sealers. It may cost a bit more but its environment-friendly feature would surely be worth the investment.
  • Concrete sealers cannot be used on new slabs. Just like most coatings and overlays, sealers can only be used on slabs that are a month old at the least. A concrete garage flooring that is still curing is very vulnerable to damage.
