Laying reclaimed parquet flooring (sorry)

[samtheman1k]

Hi all,

I've been looking around the forums and still a bit unclear on how to lay a reclaimed parquet wooden floor (mahogany). I think it goes like this:

I have a concrete floor...does this 'need' priming? How do you tell? If so, Lecol K495 is ok?

I'm thinking of using Lecol 5500, is that the best/recommended adhesive? How accurate is the 700-900g/m2 coverage? I need to do 28m2, so 2x16kg tubs should be enough?

Should I glue straight to the concrete or should you use an underlay?

The flooring supplier says I only need to remove the bitumen from the T+Gs as the bitumen bonds with the glue...is that correct? Does that mean it takes longer to set? (that's not too much of an issue if so).

Do you apply the Lecol 5500 to the floor (like laying tiles) or the blocks? Do you need to apply it to the T+G also?

In order to fill the gaps, what do I use combined with the dust from first sand. Someone recommended use PVA, but I can't see that it would be strong enough...

Sorry for the Qs, and thanks for the As!

PS: Where can I get Lecol 5500 from for less than £55/16kg lol

Any Lecol5500 still around (manufacturer stopped making it June 2010!) will be very old stock and lost its bonding power - so don't go there!

Priming of the concrete floor depends on the quality of it, is it powdery, dry, level and without cracks

Clean off all bitumen from the blocks - your supplier is incorrect, any bitumen residue will effect the bonding time with any modern adhesive, plus you will only bond the bitumen to the floor which will fail eventually. F.Ball B91 is a suitable product to use to bond the cleaned blocks straight onto the concrete - no underlayment needed (how would you bond the underlay to the floor anyway?)

You apply the adhesive with a correct notched trowel to the underfloor. As for filling the gaps with a wood-filler mixed with clean sand-dust (from second sanding so you know you have clean dust), use a proper wood-filler, not PVAC glue
