Thanks Randy. I did a test today and kind of over did it in the over-fill. I will try the tape method next time. In any event, I agree with setting the expectation levels. When they first told me what they wanted I told them it would be impossible, but we are still talking. I have a faux marble guy coming in to see about blending some of the bigger patches including a huge concrete patch.

Mr. Baird

Sorry away from the forum a while.

First step is in Keeping the perfect result expectation low with your client, and try to exceed it. Cause in the sunlight you may still see some indentions and fills will refract light differently they need to understand that.


Q: Can the grout be mixed with marble dust to get a good color match?
A: I am not sure, so I would pick a color of un-sanded grout that matches your color you prefer.You would hate to think if it messed up some how, could of the marble dust compromised it in any way. (Mixing grout = important to mix it let it set about 10 minutes then use it. Don't ever re-add water to it.). 

Q:  If the current patches are flush with the surface or just below the surface and I scratch up with a 120 Metal diamond, will the new epoxy or grout bond well to the old stuff If the application is very thin?
A: I would think not. Unless you drill them out. But it does give hope that some will adhere. Thats why you set the expectation of the client based mostly on your question. See below conversation to explain better. 

Client conversation is like this: This is a problem when the floor has these situations of the slightly settled fills. Most fills settle a little. We will do our best to over come these issues, and stay with in your budget. But keeping a reasonable budget in mind chances are there will be some of the problem remaining but much better. To fix it the best would be very expensive and time consuming. We would need to drill out most of these and them float the floor with epoxies and un-sanded grout. It may need done twice during the process needing a 12 hr cure time at least, between floatings. Being that said we will do our best and stay with in your budget.

Q: I'm wondering how much of the old epoxy needs to be pulled out to get a good bond?
A: I would use a dermal with a grout bit or something similar. Drill some wide hole straight into the fills so your epoxy can run into those and remove about 10% off the top. ( use a tongue depressor and really work the epoxy in the holes, it likes to have issues with air pockets). Note: --->If you want some of the epoxy fills built a little higher, surround the holes to the edges with a strip of painters tape, fill to the top of that. When you remove the tape it will leave the fill just a spec high so you can cut it flush with your diamond work.

Have fun
Randy

> I would cut it first with a rigid driver with a minimum of 120 metal mainly to give all fillings a good scratching so the fills will adhere to the old fills that sunk. Fill all the larger holes with a color matching epoxy and float the smaller holes with un-sanded matching grout mixed with latex. Cover with that brown roll paper if the home owner needs to use the floor. Come back next day and start your cut with 50 resin (if epoxy was over filled in bigger holes you need to start with 120 metal again, but try staying out of the metals if possible) and work up to desired finish. Spot fill any new holes as described before. Good luck
