Hi! I have been asked to put down a new MDF sub floor over which is to be installed a new vynil flooring 3mm thick. The MDF has been specified by the flooring manufacturer.
As the area requires some thirty 8x4 sheets I don't fancy the idea of screwing it down and I am afraid that pins may 'work' loose and be a problem to the new vynil.
Does anyone think narrow crown staples would be a better solution.
The spec; is for 4mm MDF and is covering a well used,dirty, but reasonably even chipboard floor.
Any advice greatfully received, Ta!
What a nightmare job! With mdf that thin you are going to have to pin it down very well and unless you can find staples with ring shanks I think they will crawl out.
What are the chances of cleanign up the existing floor and laying direct?
I agree! what a job, but "needs must....", and when in a recession!!!!
There are good reasons not to sand down the existing floor, client specification for one,but I intend to use 8x4's cut down to 4x2's which should help eleviate any tendancy to bubble but as you say well pinned down, hence not wanting to use screws. I am hoping that the crown of the staple will be, in part, held down by the new surface which, having now seen a sample, is quite hard.
Thanks for your reply and wish me luck.
Make sure your gaps between boards are non-existent and if you have any they should be filled. Otherwise the vinyl will, in due time, sink into the gaps and your customer will be complaining about lines on his floor.
