When you say reclaimed, had it already been laid before and has been removed from the floor, or has it been left lying around in storage or maybe a garage. My advice for both is this, if it has been laid before, check the condition of the base of the parquet, had it been stuck before??, evidence of adhesive residue would be clear to see. If it has come up in okay condition then if you wish you can attempt to re-lay it, baring in mind though that it may not look as good when finished as a new parquet floor would. If it has been lying around be aware that it could be damaged from moisture intake, this would cause the parquet to "swell", this might not be evident on initial inspection and may only come to light when parquet slabs are laid next to each other, they may slight or in some cases, very obvious height differences between the boards. I would recommend bring the parquet into the area that it has to be installed in, leave for a couple of days to let it acclimatise before attempting to lay. I would recommend not to attempt it yourself, but get a trained tradesman, who will know on inspection if the parquet is in a condition to be laid. Hope this was off help
