The cost to overlay or resurface a garage floor averages about $3 to $9 per square foot, depending on the preparations involved, the size of the floor, and the type of finish. Some decorative topcoats like stamped concrete and ornate overlays can cost from $7 to $20 per square foot, depending on the complexity of the design and finish.

Apply two coats of paint to a garage floor after priming for optimal results. The first coat serves as a base layer, providing adhesion and coverage. Allow the first coat to dry thoroughly before applying the second coat, typically after 12 to 24 hours. The second coat ensures even coverage and durability and enhances the floor's appearance. Additionally, applying two coats helps to create a more substantial barrier against stains, chemicals, and wear and tear, resulting in a longer-lasting finish. 

Yes, you can seal old or existing concrete, but proper preparation is crucial. The concrete surface must be clean, dry, and free of any incompatible old sealant. To check if an old sealer is present, drip a few drops of water onto the surface; if the water is absorbed in under five minutes, it's ready to be resealed. If you plan to use the same type of sealer that was previously applied, you may not need to remove the old layer. However, if you are using a different type of sealer, the old one must be completely removed. Before applying the new sealer, thoroughly clean the concrete and repair or fill any cracks to ensure a smooth, well-prepared surface.

Whether it's better to stain or paint concrete depends on your budget, desired aesthetic, and DIY skill level. Generally, staining is a more durable option because the stain soaks into the concrete's surface and won't wear away like a topical paint coating. Painting concrete can trap moisture underneath the paint layer, which may cause the concrete to deteriorate over time. However, concrete paint offers a wider variety of colors, is typically easier and less expensive to apply, and is effective at covering up existing stains or blemishes on the surface.
