In all the markets/cities/states that we clean and seal pavers in, Florida by far takes the cake when it comes to bad seal jobs that we come across. At least 50% of our business in Florida is removing failed paver sealers and re-doing the job correctly.
There are typically 2 reasons why sealer jobs go bad, and it can take anywhere from 1 day to several years before you can tell its bad.
Probably the number one cause of failed paver sealer jobs in Florida is poor sealer selection. As you know, Florida has a high humidity level and also a high water table level. This means there is constantly moisture on the surface and moisture trying to escape from the ground. Most of the sealers used in Florida are solvent based sealers which are designed to keep water and moisture out. The problem is, they also keep water and moisture trapped in the paver. This moisture and water will begin deteriorating the bond that the sealer has with the paver and when this happens your sealer turns a white color.
Our paver sealer at Perfect Paver Co is specially designed to work with the environment to allow the natural flow of moisture in and out of pavers. We are able to achieve this by using H2O (water) in place of the solvent based ingredients in our sealers. As the sealer cures, the water evaporates from our sealer leaving microscopic channels that allow moisture to flow in and out.
The term ‘sealing pavers’ is often compared to sealing a deck or sealing a basement where the goal is to keep water out. When it comes to pavers, thats not the goal. Pavers should be sealed regularly to prevent the surface of the paver from deteriorating from traffic, UV rays and rain. Exposure to these three events cause the finer materials in the surface of your paver to wear away leaving only the larger aggregates. The finer materials at the top of the paver is where all the color of your paver is held because the larger aggregate won’t absorb the color.
There are many other benefits of sealing pavers, but those benefits vary depending on the type of sealer being used.
The second most common cause for failed paver sealer is due to improper application. Unlike any of the other markets/cities/states we provide paver cleaning and paver sealing in, Florida has more unexperienced companies offering paver sealing services than any of the others combined. In Florida, sealing pavers is one of the few trades or services a company can provide without needing a contractor license. So naturally, this industry attracts unskilled and unexperienced startups due to the ease of getting started (Getting a contractor license in the State of Florida can be very difficult).
Most bad paver sealer jobs start with poor surface preparation. Due to the porosity of concrete pavers, dirt and grime can become lodged deep in the pores of the paver. If this dirt is not removed prior to sealing, it will prevent the sealer from fully adhering to the paver. We use steam and hot water to throughly clean pavers. Most other companies simply use small cold water pressure washers.

Does paver sealing prevent weeds, moss, and algae? That is a great question! We would like to be clear about our services and ensure you that we wish to provide you with the best information possible regarding your pavers.
The sealant includes a polymer additive that soaks into the sand between the pavers turning the sand hard; similar to a mortar. This creates an environment that makes it extremely difficult for weeds to germinate and grow.
Our goal is to minimally prevent 90% of future weed growth. However, there can always be certain circumstances that can alter the efficiency of the sealed pavers. There are also a few things that can be done after your pavers are sealed to allow for maximum weed and vegetation prevention in the future. We feel that it is important for you to understand that our process and service is not a remedy for poorly installed pavers (uneven, sunk, misaligned, etc.).
The number one reason weeds, moss, and algae grow between the pavers is due to inadequate or faulty paver drainage mechanisms and/or little to no sun exposure. The inadequate drainage can be caused by low or sunken areas, pavers that were improperly sloped during installation, patios that have stone walls around the perimeter (preventing water from draining appropriately), or even mounded landscape beds that also prevent effective water drainage.
When pavers are not draining properly, these areas remain damp (especially in shaded areas). Airborne organic materials begin to stick to the damp surfaces including pavers and sand joints. Over time, this promotes the growth of moss and algae. Airborne seeds from weeds and grass also begin to adhere to the damp areas. The airborne organic materials and seeds, within these damp areas, create the perfect conditions for germination. The roots then begin to grow in the shallow layer of organic material. We would be happy to address any drainage issues prior to sealing your pavers. The best fix for damp pavers is proper drainage.
How can I minimize the risk of future weeds, moss, and algae growth within my paver joints? Utilizing the following steps, you can have long term success with your sealed pavers.
We appreciate your business, and as always, we look forward to serving you in the future. Utilizing the above steps will increase the effectiveness of your sealed pavers and ensure long term success. We are more than willing to assist with these precautionary steps; please contact us for more information.
Typically, a customer comes to us requesting to either have their pavers sealed or stabilized with polymeric sand. Rarely does the client know both options exist. So, I wanted to put this informational article to share what the differences are and which is the best for your situation.
A joint stabilizing sealer is a liquid product that penetrates into the surface of the concrete paver as well as the sand in the joint giving the paver protection from stains and an enhanced look as well as hardening the sand in the joint. The joint stabilizing sealers come in a natural or matt sheen, enhanced or semi-gloss sheen and a high gloss sheen.
There’s nothing more frustrating than seeing your beautiful paver patio become infested with weeds. Weeds are probably the #1 or #2 biggest concern from potential clients of our new installation division. Because pavers are presented/marketed as an easy installation, they are often installed by DIY’ers or companies with very minimal experience installing pavers. I’ve always said that a paver patio properly installed will have minimal weed growth.
