While concrete can withstand virtually any form of damage, it is not fail-safe. Invest in sealing products that guarantee the highest levels of protection and unmatched durability for your concrete surfaces. There are different types of concrete sealers available on the market. They nonetheless should be applied professionally to work their magic.
Every step of the application of concrete sealing products is carefully handled since it affects the outcome of your surface’s sealing. The process starts with the removal of all grease, dust, and stains from the surface followed by the stripping of an existing sealer. The concrete surface should then be opened up using an etching solution before the application of the sealer.
The following are the tools used for the application of a concrete sealer.
This is the prevalent option for applying concrete sealers. There are two alternatives for the squeegees used for concrete sealing, but the ultra-soft neoprene and rounded-edge long blade are the commonly used ones. The ultra-soft neoprene is ideal for medium-viscosity sealers. It is, however, not used if the product has a matte agent and low viscosity since the surfadces might have a somewhat orange peel effect in these instances. The rounded-edge long-blade squeegee will pivot back and forth. It spreads the sealants at 150-350 sq. feet/gallon.
These are used for the application of densifiers, low-evaporation solvent acrylics, and penetrating sealers. The sprayers are low-pressure application tools that will handle sealers with a solid content of less than 35%. Before application, the sprayer is tweaked to handle the solvents, and after the application, the pumps are cleaned using solvents to avert the clogging of lines.
These are low-pressure high-volume sprayers that suffice for the application of all types of sealers. These include solvent and water-based sealants, those with low and high solid content and all resin types. Airless sprayers will allow the controlled application of concrete sealers and the application of the same to a large area within a short time. The airless sprayers are, however expensive.
Piston and Gear-Driven Pumps
These come in several options and are ideal for the application of high-viscosity sealants. They use different types of applicators for the sealant, though lamb wool applicators are the most commonly used. These suffice for low-viscosity sealers with good flow and long open times. The use of lamb wool applicators is nonetheless limited to smooth surfaces since they cannot run over rough surfaces.
These are high-volume low-pressure sprayers. The HVLP sprayer can spray thin sealers with a high and low evaporation parameter and water-based sealants mixed with medium and low viscosity solids. It covers 300-800 sq. feet per gallon when used for sealant application.
With the above information, you now realise that sealer application is not as simple as pouring it onto your surface and leaving it to dry. Several companies exist for the purchase or hire of these machines. You, however, should settle for one that invests in the latest technologies and optimal maintenance of their machines to guarantee quality sealant application.
