MB-11 Powder isn't working

>>2938634 (OP)
Actually maybe it is, I can't tell

>>2938634 (OP)
Stone anon here, what is the material? Looks like you have done some sanding? Please tell me your process. Also mb-20 is better but professional use as it can cause damage if you dont work it carefully and keep it isolated.

rough process if you are diy using sandpaper only
>use water and soap while sanding
>400g sandpaper
>800g sandpaper, do this twice, overlap by about one inch
>1500g sandpaper, overlap by one inch
>3000g sandpaper, overlap by one inch
>mb-20 compound on a white pad, if you use a machine, make a tape wall and dont let it spray out.
>first pass heavy volume of compound, maybe one tablespoon for this area, moderate water, high pressure
>second pass, remove excess chunks of powder, leave only the fine stuff or what is on the pad, use less water, increase speed, reduce pressure.
>final pass, clean all loose powder off the pad, small amount of water, glaze the area with little pressure
>hand pass cleanup. If satisfied, remove your tape wall and hand pass it with the pad and water blending into the surrounding areas
>neutralizing. If it looks great, microfiber and dawn dishsoap, hard scrub it all over.

as an added note, never use soap with the compound, it will literally neutralize the powder and make it not work.

It's quartz
It's looking like it's over

>>2938974
They're quoting me $7,000 to replace it, it's 5ft1in along the seam and 3ft2.5in along the wall
Are they trying to rip me off or is it really THAT over?

Yeah it sounds like they are charging you for an entire slab plus cutting and refinishing edges. With man made quartz, your only way to make damage disappear is to so the entire surface, edge to edge. This changes your process a bit as you will need a good variable speed grinder, diamond discs, and then compounds and pads. If this is an isolated piece you may consider two other options.

Make it all dull with a dust mask and sand paper and accept it
>wrap it
Call a local company who does gloss wrap and have the entire thing covered in a plastic film, of course research the limitations of the film once you have it.
>pro
Call a professional stone repair company

sounds stupid. sounds gay. sounds like a pain in the ass. epoxy comes out real nice looking. My kitchen came out looking like a $100k job.

>epoxy countertop
>100k

>>2939063
They are saying it can't be fixed cause the etch is too deep. Are they lying to try and scam me?

>>2938634 (OP)
If it's quartz, you gotta sand the whole thing. If it's composite - shits fucking fucked.

>>2939159
If there is excessive pitting, then yes there is a chance you will either see the pitting despite it being shiny (literally voids in the surface) or that to get down deep enough may leave such an unsightly wobble it isnt worth the effort. Theoretically you could pull a thin layer of epoxy across the pitting before grinding, but since you've already attempted polishing it may be too late (as the voids are not really exposed anymore).

Hope that makes sense
