WHAT TO EXPECT WHEN GAPPSI IS CLEANING & SEALING YOUR STONES
Please read all the information on this page
You may text Giuseppe at 631-831-3177 with any questions.
-
Restoring your pavers starts with using the best machinery to prepare for the initial cleaning. We use a hot-water steam-washing system with extractors and surface cleaners.
-
If needed, chemical solutions will be used to remove stains, old sealers, and general cleaners from the stones to facilitate the removal of any debris from the stone surfaces.
-
We also offer repairs for stones that have shifted or been damaged, to be completed before the patio is sealed.
-
As part of our restoration process, we will readjust any mulch in the flower beds that was compromised during the pressure washing, and clean the fence or house if it was dirty during the stone cleaning.
-
After our joint’s polymeric sanding installation process, we will compact pavers with a state-of-the-art vibratory compactor to allow the sand to fill the joints.
-
Our vacuuming and filter system will remove debris, sand, or dust in the pool water.
About Scheduling
-
After you give us the go-ahead to provide our stone restoration service, we will move you into the jobs-to-do schedule as a first-come, first-served customer list.
-
Please be patient and wait for us to contact you when we can provide our services. Gappsi’s primary focus is to restore your stones well.
-
We do not seal patios for occasions or parties. We seal your stones for long-term care.
-
We select the best days the weather allows from April 1st through October 30th.
-
We cannot guarantee a scheduled date. We can’t apply a sealer if it’s raining, whether we know it will rain or after it has just rained. We don’t know how much delay we will have, and it’s technically impossible to update all our customers on schedule.
About the Sealed Stones
-
Due to the natural elements (rain, snow, ice, and heat), the sealer will gradually and uniformly weather away. It must be reapplied after 3 to 5 years, and if you wish to reseal the stones, you should wait at least four years from the sealed date.
-
Stain removal is not 100% guaranteed to be complete before sealing the stones, but the sealer will hide most stains that are not entirely removed.
-
The installation of polymeric sand will reduce, but not eliminate, weed and moss growth. Dust and dirt will eventually collect on the stones’ surfaces and germinate again unless they are cleaned with proper cleaners annually.
What Types of Sealers Do We Use?
-
We use color enhancers, natural look, penetrating, or surface coating sealers. Based on the application, clients’ expectations, or our suggestions. The type of stone determines which sealer we apply, depending on the stone’s age, texture, color, and type (natural stone or concrete pavers).
-
Natural stones have different consistencies and structures, and will absorb the sealer differently. Some may require slip-resistant surface treatments, others require penetrating sealers, and others require surface-coating-enhancing sealers.
-
Concrete pavers also have different absorption, structures, and textures, so we will use the appropriate sealer based on the look you requested. For example, gray pavers would darken if a color-enhancing sealer is used, and gray silver will turn charcoal gray. Please ask any questions you have.
-
All sealers have a purpose, and to deliver a specific finished look, preparing the surface to be sealed is the most crucial part of the finished coating’s performance.
