Sealing your garage floor doesn’t need to be an expensive or time consuming process, and it isn’t rocket science. Most garage floor sealers can easily be applied with a roller or sprayer, and the garage floor can be sealed in as little as 30 minutes depending on the type of sealer used.
There are a few different types of garage floor sealers that can be used:
Concrete Densifier: Concrete densifiers are penetrating sealers that won’t change the look or color of the garage floor. They chemically react in the pores to form a hardened crystalline barrier that increases the strength and density of the floor. They will help to strengthen deteriorating concrete, and reduce concrete dusting and water seepage.
To apply a concrete densifier, simply make sure the concrete is clean. Using a pump sprayer, apply 1-2 coats to the concrete. Let dry. Applying a concrete densifier to a garage floor is that easy. Once the densifier dries, the garage floor will look exactly as it did before being sealed.
- Armor S2000: Sodium silicate concrete densifier for porous concrete.
- Armor L3000: Lithium silicate concrete densifier for dense concrete.
Water Repellent Sealer: Water repellent sealers are penetrating sealers that won’t change the look or color of the garage floor. They will chemically react in the pores to form a water repellent barrier in the pores that reduces water absorption by up to 95%. They will help to reduce staining and deterioration caused by water absorption.
The best type of water repellent sealer to use is a Silane-Siloxane water repellent sealer. Siliconate sealers can be used on garage floors, but if the concrete is dense (which most garage floors are), then a white film will be left behind on the surface.
- Armor SX5000: Solvent based Silane-Siloxane water repellent sealer.
- Armor SX5000 WB: Water based Silane-Siloxane water repellent sealer.
To a apply a water repellent sealer, simply make sure the garage floor is clean and dry. Using a pump sprayer, apply 1-2 coats to the concrete. Let dry.
Which is better, a concrete densifier or a water repellent sealer? If you have issues with concrete dusting, or if you are concerned about the strength of your concrete, a concrete densifier is the best concrete sealer for your garage floor. If you don’t have dusting issues, but just want to seal your concrete to reduce damage and deterioration caused by water absorption, then a water repellent sealer is best for your concrete. If you love the idea of a penetrating sealer, but want more protection against staining, or if you want to change the look or color, an acrylic sealer or concrete coating is a better option.
Acrylic Sealers: If you want a low to high gloss finish, or a colored coating, an acrylic sealer is the easiest coating to apply to a garage floor. In most cases, an acrylic sealer can be applied to a clean and dry floor.
Acrylic sealers are very easy to apply to concrete. First, make sure the garage floor is clean and dry. Oil stains should be removed with a degreaser, or concrete cleaner. Once the concrete has been cleaned, allow to dry for at least 24 hours. Using a roller or sprayer apply the first coat to the concrete. Water based acrylic sealers need to be recoated in accordance with application instructions, solvent based acrylic sealers can be recoated the next day. Let dry, and keep free of foot or vehicle traffic for 48 hours.
Acrylic sealers will resist most liquids spilled on the surface, but if the spills aren’t cleaned up immediately, they can cause the acrylic sealer to delaminate or peel. Acrylic sealers are best for use on garages where oil, gas, and other fluid spills are not a primary concern.
Foundation Armor manufactures several types of acrylic sealers, and which acrylic sealer is best for you depends on what you want your concrete to look like once sealed.
- Darkened wet look, and a low to high gloss finish: Foundation Armor solvent based acrylic sealers will darken the concrete to give it a similar appearance to being wet, and provide a low to high gloss finish. If you want the most color enhancement you can get with an acrylic sealer, solvent based acrylic sealers are the best option. Popular products include the Armor AR350, Armor AR500, Armor AX25, Armor LV15, and Armor LV25.
- Little to no enhancement to color, and a low to high gloss finish: Foundation Armor water based acrylic sealers will offer a very slight enhancement to color, and give the concrete a low to high gloss finish. If you like the color you have but want a slight enhancement, water based acrylic sealers are the best option. Popular products include the Armor WB15 and Armor WB25.
- A semi-transparent gray or brown tint, and a low to high gloss finish: Foundation Armor semi-transparent tint packs are a great option if you want to add color to your concrete coating, but still want to see the concrete below. They can be added to any Foundation Armor solvent based acrylic sealers. Foundation Armor also manufactures the Armor AG Brown seal which has the semi-transparent brown tint already mixed in.
- An opaque, paint-like color, and a low to high gloss finish: If you don’t like your concrete and want to completely cover it (similar to the look of paint), Foundation Armor Acrylic Color packs can be added to any Foundation Armor solvent based acrylic sealer.
Concrete Coatings: If you want the most protection you can get for your garage floor, you want an epoxy or urethane coating. While these types of coatings require more prep-work, they are designed to out-perform just about every type of sealer or coating you can apply to a garage floor. Urethane coatings like the Armor UTN60 or Armor UTX60 can resist oil, gas, and many harsh liquids and chemicals. It is best to thoroughly read the applications for these products to see if it is a task you are up to! Foundation Armor technicians are also available to help walk you through the application process, and answer any questions you may have.
