Concrete Sealing Aerosol Application Products
Spray concrete sealers are as impactful as environmental factors to the final outcome. The right tools are important to the application, thickness, and overall performance of the sealer. There are general guidelines and methods for the application of concrete sealing, but you should also consult the manufacturer’s instructions and recommendations about installation.
It is better to apply concrete sealer in thin coats, one over the other, as opposed to a thick and heavy coat. There are some things to consider if you want to efficiently apply liquid sealer on a surface and ensure that it will harden successfully. First, you need to find out if the sealer is solvent- or water-based. This will determine the rate of the sealer’s evaporation. You also need to find out how much the sealer’s solids content is. Lastly, you need to find out if the resin type is epoxy, acrylic, and polyurethane.
LPHV (low-pressure, high-volume) or airless sprayers
Usually, these sprayers are the top choice for applying sealer. Application can be easily controlled, which means that large areas can be sealed in a short time. They can be used for solvent- and water-based sealers with either high or low solids contents. All types of resin are also acceptable. However, the downside to these sprayers are their high costs.
Pump-up or low-pressure sprayers
If you are using a solvent-based sealer with a solids content of under 35%, these aerosol cement sealers are the best for you.
Roller
This tool can be used to apply solvent- and water-based sealers. It is best to use a roller with a ¼ – 3/8-inch nap. Just make sure to avoid sealers with solids content at over 35%. Rollers are also unsuitable for rough surfaces. For stamped or textured services, it’s best to use a sprayer first before using a roller.
Lamb’s wool applicator
This applicator is a wool rag covering a wooden block. This is best used for solvent-based sealers with over 35% of solids like polyurethanes and epoxies. You can apply cement sealer on smooth surfaces with this applicator.
T-bar
This is a metal tool with a straight edge. It’s best for a smooth surface and a concrete sealer with high solids content like polyurethane and epoxy.
Micro-fiber applicator
This is a pad made with synthetic fiber and is suitable for water-based sealers with low solids. It works best on smooth surfaces and for applying thin coverage.
Synthetic closed-loop mop
This applicator should be used exclusively for spray concrete sealers with water-based finish.
