Parquet adhesive

[malcolm]

I have some oak parquet I want to lay on an existing concrete floor. The floor doesn't have a damp proof layer so it would probably be useful if the adhesive has some damp proof function. I don't want to build up thickness as the finished level is already going to be too high. Any recommendations?

In the snug I have pitch pine parquet and that has bitumen adhesive. I replaced some of that using Black Jack but it's really stinky and takes months to dry. Something more sensible this time around.

You can always DM me Malc.

Does your parquet have bitumen on? I always scrape it off both concrete and block but they say you don't have to... in that case you need to use either Lecol 5500 or Sika Sikabond 5500, solvent based as they stick to bitumen or Ball F21 dipping emulsion.

I always use a liquid dpm but not sure what works over bitumen. You have to use the liquid dpm and adhesive as a 'matched pair' contact the manufacturer and they will tell you which one to use.

If you don't have bitumen to contend with then you are better off with a flexible MS hybrid. I normally use Wakol MS260 or MS262, but you could use Bona R848, Quantum or Titan. All act as a moisture barrier if you apply them thick enough. Both companies sell compatible notched trowels and both companies have excellent technical support.

If it's a very small area you can use the 600ml foil sausages but then you cannot put down a dpm layer.

You will have to ask Alec or Iain at Bona what the differences are, I cannot remember who I spoke to at Wakol before I ordered a 270kg pallet but he was super knowledgeable. I think Bona R848 is great for parquet. Bona Quantum dries harder and is supposedly better for very highly stressed floors. I think most MS / SMP adhesives are 'hard-elastic' Quantum and Titan are initially 'hard-elastic' but cure to 'hard-hard'. I'm not sure if Wakol and Sika have equivalents. I've only ever used the hard elastic type, but used over 1,000kg and never had any issues.

I don't have any bitumen on the floor or the parquet. It's about 50m2 of tongue and groove parquet recovered from a school in Poland, each piece around 16 inches by 2.5 inches and all clean and unworn. The concrete floor is mostly uncontaminated but I'll need to remove some lino that has been glued down. It was going to be a winter project last winter but I got too fussy overthinking things so it didn't happen. I've since figured out that if I match the kitchen floor level instead of the snug floor level I don't have to dig the concrete up.

Thanks for the recommendations - the Wakol stuff looks good - it's a combined downstairs room and corridor. Liquid DPM makes sense just to be on the safe side.

Yes, liquid dpm is cheaper and thinner, using the adhesive in a thicker bed only makes sense for commercial jobs where time is money. You can use any adhesive with that parquet. I mainly use Wakol, sometimes Bona, but use a lot of Everbuild (Sika) for repairs, those are the main 3 I trust. You will probably need 4 tubs, so about £500.

Get a couple of notched trowels and buy a couple of decorators scrapers for cleaning, I never used wipes for decades as being bad for the environment but very recently started using these
no idea how I managed without them previously, cleans hands, tools, cat etc even from MS adhesive.
