Just been to look over a job for a local builders . Theyre supplying materials for the job and they have got stopgap 300 . The areas which I need to latex have a thin coat of old black Marley tile adhesive on the concrete floor . It looks as if the tiles have been up for a long time and the adhesive is dead. If primed with p131 will it be possible to use the 300 or is it that a risk. Cheers in advance .
I wouldn't If it's a domestic job then use a bag & bottle, not water based.(it'll be too strong) Can you not grind the floor back?
Its a risk. 50/50 mate, either it will be fine or it will fail. Your the one issuing the guaranty tho.
Did it in my own house and has been down for 4 years and is solid. But being my own house the risk is my own.
It's always fine until it fails... That's where you will lose more than just your reputation... it'll cost you too..... Grind it off
Very dodgy you'll only get the blame if it goes wrong Grind of the bitumen residue off first though then your good to go.
FBall says neat p131 and 300 is ok. But it will depend on your interpretation of clean, and theirs. Grind it back, not worth the risk.
Cheers for the opinions lads . Think from that response I'll tell the builder I'm not prepared to use the 300 over the bitumen. I would buy 1200 and swap it for the 300 but I very rarely use anything other than bag and bottle now. Cheers again
You have a very good point there Mario...... let me think about this..... if we was to have a good grinder......and then we ground the floor flat and removed adhesive etc....... I think you might just be on to something here Mario. Is the answer - I have lots of money so lets go the pub?
However you only have to remove 70% of the adhesive to use 1200 for example, so if I quit there I might as well but a compound down. Not sure I would quit tho.
No, incorrect answer... the correct answer is.. you buy the grinder from me and then take me down the pub to say thank you.. for saving you lots of bucks on all that latex...
Did you miss the bit of it being in my own home and the risk only being mine. Or as its not correct practise just wanted to point and say your wrong?
