Upon further research, I have read that a channel drain tends to want to pop up over time unless it is encased in concrete.

Water will drain to the lawn which is below grade.

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...

Would the process be faster, including the clean up time, if I wet grind?

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...

OK, now for a follow up question. Given that a sealer needs to be applied at a specified gal/sq ft rate, what is the best way to ensure that I am applying at or near that rate? My first thoughts are to use water and a bucket to set the nozzle to a known flow rate and then determine how many...

To the best of my knowledge the coating is some type of 1-part paint. Acetone does not affect the coating, so it is not water based. The entrance to the house is on the stem wall and the paint has worn in some spots due to foot traffic.

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...

OK, I see the downside. Thanks. What if I did not use flakes? Are there any issues to using acrylic wax as a sacrificial layer?

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...

Bump! Anyone? What did you use/recommend?

OK, I fully understand that some products include solvents and so are not 100% solids. So, when the term "low end product" is used, is it being used to describe products that are not 100% solids? Is that all there is to this message?

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...
