Stripping of Cloudy/Milky Sealer from Pavers or Concrete
Here at Sealing Specialists we pride ourselves in being one of the only companies in Central Florida to offer sealant removal as an option to our customers. Over 50% of the jobs we are called out to do, are to repair other companies mistakes and shortcuts. Unfortunately for the customer, this is not always their fault. Believe it or not, there are many companies out there that will quote you a low price, use hardware store bought sealer, and apply it to your surface without having proper knowledge of the sealing process. It is also not uncommon for these same companies to ignore your phone calls after work is complete, to avoid making fixes or paying for another company to fix their mess.
Solvent based sealers are most commonly responsible for the cloudiness that shows up on a surface shortly after being sealed. Unlike water based sealers which penetrate deep into the pores of the paver, solvent sealers are thick and sit on top of the paver surface. These sealers block out water from penetrating the surface, but unfortunately also block moisture from being able to leave the surface. For this reason, the pavers will appear milky white as moisture continues to be trapped underneath the sealer. Solvent sealers are not environmentally friendly and will make paver surfaces slick. Some also lack the ability to lock in sand. As one rain storm rolls through, a customer will be left with a mess to cleanup once work is complete.
Other reasons why a surface may appear to have a cloudy appearance is usually related to poor sealing techniques. For instance, sealer should never be applied with a paint roller, but rather sprayed. Using a roller to apply sealer will only leave visible lines up and down your surface. Also, once a surface is sealed, it needs time to cure. If rain comes down on the surface before it has fully cured, the sealer that was just applied will begin to cloud up. The good news is, we can fix all these problems!
If we find traces/signs of existing sealer on your surface we take additional steps to address the problem. In order to prevent white, cloudy discoloration from forming or getting worse, we suggest removal of the sealer that is there. Sealer cannot be applied over already failing sealer. Should the customer decline this option, we will not be held responsible for any discoloration, flaking, separation, hazing, etc from adding new sealer on top of existing sealer.
Stripping consists of first applying a stripping agent to the surface. Once the agent has dwelled and sufficiently activated, vacuum pressure washing can begin. We use a vacuum extraction system in correlation with our high pressure washing system to remove and collect the stripping agent, sealer, and sand from the surface. With our vacuum extraction system, we are able to extract and collect more than 90% of the mess we make. Stripping with our collection system is cleaner than a regular pressure washing of your surface.
Chemical-Free Steam Cleaning
Sometimes pressure washing a surface alone will not be enough to remove tough, stuck on dirt and grime that has been left to sit on pavers for years. To combat this problem we are able to offer our customers chemical-free steam cleaning. We use high quality, commercial equipment that is able to heat the water that passes through our pressure washer to 250 degrees. At temperatures this high, stuck on dirt and algae can be lifted from the surface and within pavers without causing damage to the pavers. The high temperature is also very effective in killing mold.
