Lifting Porcelain Floor Tiles & Addhesive

[Argyll Eagle]

I have to lift 62 square metres of porcelain floor tiles. I'm sure that the tiles can be lifted easily using a power chisel, but how on earth do you get the addhesive off the concrete screed in order to lay new porcelain tiles? I have underfloor heating pipes running through the screed. Is it going to take ages to remove the addhesive?

Experienced advice would be most welcome.

if adhesive is well and truly stuck , its very labour intensyfing to remove you would be better to self level over old adhesive, prime first . dave..

if its got underfloor heating the ady will probably be 2 part flex and will be a nightmare to get off i would just level it with latex leveler

Thanks Dave

Problem is that the adhesive must be lifted as I can't raise the level of the floor. The tile supplier is having to foot the bill, so if you know the best way to remove the adhesive I would be very grateful.

try one of those industrial scrapers on a pole , hard work but will lift it up , i would'nt use power chisel to lift adhesive residue as this could cause damage to heating pipes if concrete breaks and punctures pipe. hope this helps. dave...

p.s. i know its hard work but price accordingly..

Any idea of time involved?

well , if adhesive is stuck well could be 2 days graft, but this only a guess depends on how well adhesive is stuck and how hard you work lol lol. just make sure you price well if case of worst case senario. dave....

p.s. is there no way you cant re-level , onlt talking about 10mm increase in height.

Much thanks for your time. Resetting floor level is not an option as levels set to low profile door threshholds, attached house floor level and outside decking. The new build is our architect designed, dream retirement home which has geothermal underfloor heating and floor tiles throughout. Our tile supplier sent us our floor tiles in two separate batches. Problem is that second batch (different batch number) is totally different from the first batch which are no longer available. We are talking about very expensive porcelain tiles.
