Subject: Removing sealer
We have beautiful brick pavers in our neighborhood. Someone sealed theirs with a colored sealer which must now be removed. (Clear is ok) Is there a chemical removal or can they be sandblasted? Thanks, Pam
...............................
Pamela,
Yes, there is a product to strip sealer off of the concrete pavers. Techniseal Sealer & Paint Remover.
Do not sand blast the pavers, since this will expose the limestone aggregate used in making the paver and you will lose the color.
There is a facility in your area located at 39 West Landstreet Rd, Orlando, FL 800 226-9117 where you can buy the Techniseal Sealer & Paint Remover.

Subject: pavers and coping
should the pavers be at a lower level than the coping to prevent run-off into the pool, is it ok to have the pavers equal height with the coping? Also, after the pavers are laid, how long should I wait before sealing the pavers and is there a better sealer than another?
.............................
The coping should be at the same elevation as the pavers, or the tops
should be flush this eliminates the worries of stubbing toes or
tripping. However the coping should have been set at the same slope or
pitch away from the pool that the pavers have away from the pool
minimizing the chance of water running into the pool.
Sealers:
The timeline you are concerned with for sealing is when the pavers were
made not when they were installed. Pavers are made of concrete and
therefore need 28 days to cure prior to the application of sealer.
As far as the quality of sealer any manufacturer will tell you that
theirs is the best, however it has been my experience that because of
regulations from EPA and other governing bodies they are all pretty
equal.
So now we have to look to what types of sealers we have to offer. There
are two basic types of sealers, one is water based and the other is
solvent base. Since pavers are made of concrete to get the colors the
manufacturer has to add pigment to the paver. Since these pigments are
added the sun and other elements may cause the pavers to fade or lose
their brilliance over time and both of these sealers will prevent
fading.
Prior to sealing the pavers must be completely cleaned with a chemical
paver cleaner to remove construction dirt and any other substances that
may have found its way onto the pavers that would inhibit the sealers
ability to bond to the pavers.
Water base sealer is a penetrating sealer that penetrates into the
paver. Therefore one coat of sealer is all that is needed to seal the
paver additional coats are a waste of time and money. The water based
sealer typically does not change the appearance of the paver but it does
protect it from fading and from minor staining.
Solvent base sealer is like stretching a sheet of plastic over the paver
and additional coats will add to the shine similar to adding coats of
wax to a floor. Additional coats will also reduce skid resistance as the
coats build up on top of the paver's. The solvent based sealers are
typically recommended for pool applications as it gives the owners time
to wash of chemical spills such as chlorine to avoid damage to the
pavers. Solvent based sealers are also a bit more temperamental during
application, although both sealers need to be completely dry prior to
application with the solvent based sealer it is imperative as moisture
may be trapped between the paver and sealer, and this will produce a
white cloudy appearance on the pavers.
Both sealers will need to be maintained over time, typically the
re-application time is 2-4 years based on amount of use and appearance.

Subject: Thin Pavers and existing drains
I considering installing thin pavers on my pool patio. The issue is the drains. Some estimates say they will go over and others say they will add and extension. which is best and how would they add an extension and what product is best if they do raise it.
The look would be better without drain but what keeps the sand from washing in and the mold from growing?
................................................
Allen,
Depending on the type of Deck drain you have there may be an extension available, however it has been my experience that they do not sit very tight on the existing drain and over time have problems. I have always preferred coming in and cutting out the old drain carefully and sitting in a new drain, the cost is usually no more than the extension. You must definitely put sealer on the drain where it meets the existing concrete deck otherwise you will lose your bedding sand. I also recommend using the sealer at the top between the paver and the Deck Drain, this helps minimize your mold problem.
However I like your thinking on not having the channel drain at all if possible. This would have to be determined on the jobsite. Depending on how the deck drains you maybe able to just cut in two or three 12”x12” drain inlets and use the existing channels into the drain inlets to drain the water under the deck. A good installer can assist you with this.

Subject: Pavers over cement pad
Damon,
Thank you for your interest.
In response to your questions below, yes you can lay the pavers directly on the cement pad. The adhesive that we recommend is an adhesive from Techniseal. You can find this adhesive at any of our dealers.
Please let me know if you have any additional questions. Good luck with your project.
....................................................
I have a back porch area that is inset into the back of the house, so the pad is inclosed on three sides opening out to the lawn. I would like to cover this area with pavers. I have enough room to raise the porch 4 inches. There is already a slope from the house to the lawn. My question, can I lay the pavers directly on the cement? and what would be the best adhesive to use on the outside edge (next to the lawn) of the pavers?

Subject: concrete pavers
I have 2 areas, 280 sq ft and 224 sq ft, that need to be paved or decked. Both areas are close to the ground so wood is not my first choice. I am on a very tight budget that translates to a DIY project. Pavers of any kind are normally $3+/sq ft in this area. Can I use concrete cap blocks as pavers? The current price at Home Depot would be around $1.60/sq ft. The larger area is underneath an existing porch while the smaller area would be fully exposed to the elements. I am assuming I would need to apply a sealer to the blocks. If I wanted to stain the blocks would it be better to stain them prior to installation. Thank you for any advice you can give me. Katie
.................................................
Thank you for you inquiry. I assume you are talking about a 2" x 8" x 16" solid block when you say cap block. So companies do sell them as patio stones and would prove more durable than wood. If you are proposing using these suspended and not supported by a solid base, I would not recommend that application.
Sealing concreted can improve the longevity of concrete, it sounds like you may be dealing with a lot of moisture. If you want to stain them please consider if there is a moisture issue then it will need to be very dry and may make sense to prestain.
