Updating your garage with a new concrete floor is the ideal way to refresh the whole space. Once the cement sets, you'll need to choose a type of sealer as porous concrete will stain and weather quicker when left to itself. Here are several options to consider.
If you have grey industrial-looking concrete, you might like a penetrating sealer. These products seep into the concrete, protecting it without changing its appearance. Penetrating sealers, such as silicates and silanes, are also ideal for outdoor pathways and patio areas. A benefit of these products is that they allow moisture within the flooring to evaporate; they don't trap it within by creating a closed film over the top.
You might have beautiful decorative stencilled or stamped concrete, or exposed aggregate, in your garage and wish to protect it. One possibility then is to apply an acrylic sealer, which can be either water or solvent-based. These products, which also suit indoor surfaces, form a protective cover on top of the floor. Choose from various sheen levels to bring out the colour and design within decorative surfaces.
For a more durable option, you could go with polyurethane sealers, which are usually thicker than acrylics and trickier to apply. Extremely tough with high resistance to abrasion, transparent polyurethane finishes protect surfaces from high levels of foot traffic even in public spaces. Thus you can feel assured that your garage floor is safe. Select the degree of shine to enhance the beauty of the concrete underneath. Polyurethane finishes also suit indoor applications.
Epoxy sealers can yellow with UV exposure, so reserve them for indoor spaces. If your garage doesn't receive sunshine, however, this shouldn't be a problem. These sealers typically create an attractive glossy surface, which is non-porous and abrasion-resistant. Whether inside your home or in the garage, you can improve the flooring with either a clear or coloured finish. Because some of these finishes seal the surface, they can trap moisture within the concrete rather than allowing it to breathe.
Penetrating sealers retain a natural look for your garage flooring. To enhance textured and embellished surfaces, choose concrete sealing that creates a protective coat, such as an acrylic, polyurethane or epoxy product. Considering the design, choose the most complementary sheen level. Different products vary in whether they allow moisture within the concrete to escape. Ask your contractor which is the best for your garage.
