    I need to stick an acetal/perspex splashback behind my lavatory. Basically I want to just knock the old tiles off, sand one side of the acetal to give it a key and then apply the adhesive and put the acetal in place to cure. Not keen on removing the old tile adhesive as its an awkward working position. So the adhesive needs good gap and strength properties on acetal. What would be the best adhesive for this task? Polyurethane based? I thought of using a couple of tubes of no more nails? Contact adhesive might not have the gap requirements for the old tile adhesive surface.

    stixall would work well. A bit more pricey than no nails,but better grab

    Why don’t you just stick the Perspex panel over the tiles (after suitable pre)

    You say your not keen on removing tile adhesive, plus you can never tell how cleanly the tiles come off until you start

    Issue is ( as I see it) the Perspex is best going over a solid, flat surface - you may end up with a relatively flat surface if the tiles just pop off but…..

    If you kinda use ‘dot and dab’ method with blobs of adhesive which allows you to level the Perspex, then you have voids behind which may allow the Perspex to flex

    I would consider cleaning tiles then simply bond the Perspex to tiles using decent quality silicone

    The reason I don't want to stick it over the existing tiles is because they are poorly laid overlapping etc so they need to come of up to a height of 600mm from the ground. From there up they are okay. Hence the reason for this entire exercise.
    Access behind the toilet is awkward which is why the last person probably did such a poor job up to the 600mm mark.

    Whatever method you decide to go with, remove the toilet (if you can ?) to gain better access and make the job eaiser / better finish

    However long it takes you to remove the toilet, will probably save youn this time plus more in prep work and fitting the perspex - (not always an easy job though I realise, depends how spigot conects to soil pipe)

    As your going over the old tile adhesive, I would prime the tile adhesive with SBR @ 1-4 water to improve the bond plus seal dusty surfaces
    Then silicone or grab adhesive will do the job

    Good luck, hope job goes well

    any kind of hybrid polymer adhesive (stixall, ob1, ct1 ect) would be perfect.
