Wow - that is a lot of damage.... Most companies that sell flooring epoxy will also sell a crack and joint filling compound, which is mostly epoxy and fumed silica. It should have the consistence of paste and you can apply it like drywall mud or grout, using a spatula. Normal surface...

Its hard to tell here, but this is the primer coat filling in around the flashing: Here are some pics of the membrane layer. It is applied at about 24 mils thick.

Thanks for the info thegarageguy. All I know about the current system is that it was installed by a roofing company, it has some kind of a black rubber membrane, copper flashing, and a cementitious overlay. Polymeric systems are used in almost every waterproofing or decking system. Either in...

I'll start with posting 'before' pictures below. As you will see, I'm trying to fix the type (I think) of system thegarageguy is talking about. Currently, there is black rubber membrane underlayment, copper flashing, and cementitious topcoat. There are two floor drains and 3-4 ports off the...

Very nice lighting!

I'm doing a similar piece of work at the moment. A concrete overlay on a fourth floor rooftop / porch which is now leaking. Outside of the sealing factor, the big problems with this type of application are the daily direct sunlight and the heat associated with a rooftop application. Both of...

I'll attach some pictures of a full broadcast floor that I did using mica chips from Original Color Chips. The mica chips are pretty tricky to use, as the are very light and cover poorly. However, they do make a nice looking floor. When the sun hit the floor in the pictures, it really lit up...

I use Shark Grip from H&C at the Sherwin-Williams store in about 90% of the top coats that I put down. I add about 2 Tbl per quart of top coat. It knocks some of the gloss off the floor and makes it significantly less slippery. However, it is not coarse enough to make cleaning especially...

I do a lot of work in new construction garages. I typically find the floor in the condition you reported when I start to work on it (drywall mud, paint, stain, sawdust, nails, screws, scrap lumber, etc.). The houses I work in usually are not yet 'finished' and I spend about 30 minutes cleaning...

Be patient when you are spreading the flakes and don't ever get 'too many' in you hand at one time. Throw the flakes as high as you can to allow them to spread out on the way down. My two cents :)

Top Coat vs No Top Coat: There is a lot of science (search tribology) around friction and wear, including the wear of coatings. Generally, the 'harder' a coating is the faster it will wear and scratch. Most top coats are a bit 'softer' (Young's Modulus is one of the real measurements, if you...

I've always found a thinner first coat and thicker second coat to give better aesthetic results. A thinner first coat will give you less chance for bubbles and such, and a thicker second coat lets you have more material to self level out and yield a smooth finish. Definitely talk to the...

Most manufacturers advise you to wait a minimum of 30 days. The goal is to allow all the water in the slab to either react or evaporate.

Nice job on the chip broadcasting! That is harder than it looks to be, isn't it?

Here is a picture of 1/8" full broadcast in a garage. Did you mean full broadcast or random?

You might have some really hard concrete that you are dealing with. If you are trying to grind 3500psi concrete, a diamond cup is very slow going.

I use the Shark Grip from Sherwin Williams regularly; it really works well.

Commercial epoxy systems are typically tolerant to +/- 10% of their mix ratios. Outside that, a lot of other conditions (contaminants, humidity, color loading, etc.) start to really effect whether or not you'll get enough chain building to consider your coating cured. It sounds to me like you...

Thanks for the welcome! Right is right, regardless of your agenda :) The under the sink thing (I'm calling it DripGuard for lack of a better name) I'm trying to sell for $299. That includes matching your countertops or a custom complimentary color scheme as well as about 1" of cove base with...

Here are a couple pictures of inserts done over an Original Color Chips metallics floor that I did in the past. I installed the inserts on top of an epoxy grout coat and under a polyaspartic topcoat. edit -> the metallic chips were full broadcast, so not 'over' any color. They covered...
