Tiling problem

[TulsaRemodeler]

Went and looked at a potential job today, included 65 sq ft of kitchen floor to tile, right now glued down linoleum over concrete slab. 81 sq ft of dining room to tile, commercial vinyl squares glued on concrete. Height is an issue so no backerboard.

Is there a priming product to use or does every little bit of adhesive gotta come off? And if so how? Never encountered this situation.

Thanks! Would be much nicer to use then a petroleum product. I already had a headache thinking about it.

After taking the tile off, try putting water on the adhesive and see what that does in a few minutes.

You might get lucky and it may be water-soluble.

Last place I did was. Just wet it, wait a few minutes and scrape it off.

You wouldnt use a backerboard over concrete slab anyway, so thats not even an issue... Usually a scraper and scarifier is used to get the adhesive off. Some thinsets are approved for going over the cutback adhesive, but its still not the best idea.

The non-toxic citrus stuff may take the bulk of the adhesive off, but any film left on the concrete, or even in the pores of the slab may affect adhesion of the new tile. Test the slab before you tile by sprinkling some water on it.. If it absorbs into the concrete evenly, you're fine... If it doesnt, you still have adhesive residue, and need to grind it down... A cup grinder will work to rough up the slab after all the adhesive is off, but if dust isnt an issue here, you'd be better off skipping the chemicals and just renting a big machine to get it all done quickly.

Thats one of my concerns, making the concrete porous enough for thinset adhesion, tough to put a price on this removal, I was at $3 sq ft, then $5... Oh yeah tree fiddy :grin:

My local rental guy charges $75 for the day to rent a machine.. If you've never seen one, they look a bit like a floor guys drum sander.... Not too intimidating... You dont have a big area to do, so you'll easily be done in a day.

Sell the service... Listen Mr. Homeowner, I know some contractors have no problem tiling right over the adhesive and giving a taillight warranty, but I only feel comfortable doing this to industry standards, and that means having clean concrete to set your beautiful new tile over.

Good luck...

I'm gonna figure on going that direction, warranty work?:thumbsdown:

Think hours on the removal...not per sf. Be thorough in your explanation and if the HO wants a good job, you should be able to land it even if the other guys didn't catch the possible difficulty and bid in for it. HD rents a large scarifyer or cup grinder with a bag that will catch the majority of the dust. Better safe than sorry.

I came up with $700 for 145 sq ft thinking it out by the hour, its a flip house, guy has other work. You ever heard that one before? :grin:

If you have a SDS, they make a big scraper blade that goes into that, eats all sorts of floor coverings, tile, sticky tile, sheet vinyl.

I also bought a scraper blade thingy that went in my sawzall, that worked like a champ and was pretty cheap.

That blade for the sawzall sounds neat, didnt know they made something like that. Dont know what a SDS is so I probably dont have one :)

Like a big ass Hilti or Bosch rotary hammer drill.

I am pretty sure the guy that invented the spyder scraper lives just about 30 minutes north of here on a nice lake.
I guess he invented that and then it took off and he sold it for some big bucks.

Yes, it usually comes right after they say 'if you do me a good job and treat me right, I can have a lot of work for you down the road...or 'I know a lot of people around here'. Hate to be a rainer, but rarely has that ever worked out for my. I seem to do better working for people who only have one house and don't know anyone.:laugh3:
