I need a drainage solution for my existing concrete patio. Calculations indicate that I need to drain 10 GPM for a 4 inch/hour rainfall. A small channel drain will do that. There is only normal foot traffic. For narrow channel drains like the ones used for pool areas, is it necessary to cut out...

I just finished dry grinding 250 sg ft of acrylic painted garage floor using the Diamabrush prep tool. Instead of the 2-3 hours time estimate that I had received from various sources including this forum, it took about 5 hrs. The majority of that time was spent grinding the acrylic off...

I will applying epoxy to my garage floor one half at a time so I don't have to move everything out. The epoxy kit includes 1 gallon each of base and hardener. I will need half of the kit (one gallon mixed) for each half of the floor, so I need to split the contents and mix one half at a time...

I need to remove paint from a stem wall before I apply epoxy. The wall is 3 inches high and 1 inch wide with a rough surface similar to my driveway. If I hand grind it, I will have to do it wet or have a huge dust storm. However, because of the surface roughness, its not clear that the paint can...

I am planning on a Rustoleum Professional epoxy floor with flakes and Sharkgrip in the final coat. I know that it is advisable to apply a top coat to protect the flakes and prevent dirt from accumulating around their edges. As an alternative to an epoxy or polyurethane top coat, is it possible...

On his website, epoxyproducts.com, Paul Oman makes the statement, "Note that modern epoxies do not require an "induction period" or "sweat in" time. This is a amount of time you must let the epoxy sit after you mix it and before you use it. If the epoxy you are considering requires this...

I will be applying a solvent based acrylic sealer to my driveway and patio using a hand pump sprayer. The solvents in the sealer are naphtha, ethlybenzene and xylene. I will be resealing about every 3 years, so I need a reusable sprayer or a cheap throw away unit each time. I am aware of the...

I am considering applying a siliconate penetrating sealer to my garage floor. However, there has been some mention on this forum, that topical coatings cannot be applied to a sealed floor. Is this true of all of the more durable topical coating types? If I do use the sealer, can it ever be...

Obviously, some epoxy will remain on the bucket and tools and some may be accidentally dropped where it should not be. What is a reasonable percentage loss allowance? Does the loss allowance vary depending upon the percentage of epoxy solids in the coating?

I am considering using a 100% epoxy coating, and have two questions. Near the door, the sides of the floor slope down toward the entrance (see first pic). Will there be any issue with the epoxy tending to flow down the slope? What do you recommend I do with the vertical transition from the...

The sides of the garage floor are higher than the main level at the door for drainage reasons I assume. See pic. I doubt that I would be able to lay VCT in this area. I am sure that others have had this issue. How did you finish the curved areas?

I will be grinding a garage floor that has a water based acrylic coating. The original contractor did not etch the floor before application. I will wet grind using the 16 inch Diamabrush tool. What is a reasonable time estimate to wet grind and clean 600 sq ft?

My driveway was painted four years ago with a solvent based acrylic basecoat with contrasting color dots sputtered on and a clear solvent topcoat. There are two small, subtle white haze spots, each about 3 inches in size that cannot be removed by scrubbing with a cleaner. I understand that these...

One internet site discounts using acrylic sealers from paint stores and DIY stores because their products use "inferior" acrylic resins. Yet, I can find no reliable information to back up that claim. Is this just a marketing ploy, miss-information, or is there really some acrylic resins that...

My driveway was painted four years ago with solvent based acrylic paint and sealer. It appears that its time to be resealed. Florida's sunny weather is probably a durability concern. What do you recommend as a best value sealer?

Sealer was previous applied to my driveway which is painted and to my patio which has decorative concrete. I believe an acrylic sealer was used in both places. I have read that an acrylic sealer will last from 1 to 5 years depending upon its quality How can I tell if its time to re-apply a sealer?
