joint cement

[will2000]

hi does anybody know of a heavy duty joint cement which will set quick and set very hard? Thanks

 

[bookahandyman]

what you doing? what are you trying to achieve?

 

[will2000]

im looking for an alternative way to fill gaps in wooden floors. I believe i need jointing cement with a minimum shrinkage something that will set fast and hard. the only thing i can find is easi fill 45 but was unsure weather this would set hard enough?

 

[bookahandyman]

do you mean the gaps between flloorboards? Are you covering these wooden floors after you have filled them? how big are the gaps?

sanding and finishing it with lacquer the gaps are 5mm

i once saw somewhere...and i cnt remember where but someone mixed some wood filler up and put shaveings of wood (sawdust) into the mix, when i asked why they said it helps bind it together to set nice and hard but if it needs to flex it still can, plus after its dried you can sand the whole floor down and stain/varnish/laquer or so forth, it looked the dogs danglies when it was finished.
not sure if this is the sort of thing you are looking for just my 2 pennies worth

oh well there you go same finish as the job i saw it on, you just beat me with a reply before i got there

thanks for the respone... yeah the cellulose filler you are talking about is quite expensive and isn,t very good, it falls out, im looking for and alternative? i have heard of a product called durabond 20 which is what im looking for but you can,t get it here, or so i think, im looking for something the same?

i am not concerned with the colour as i will dye it the desired colour

If your sanding them with floor sander then do a run over them with the sander and collect the dust from bag, then mix the sawdust with PVA and when a thick paste put in gaps, this will dry clear with a wood colour same as sanded wood. then sand again when fry. very time consuming but the best result. failing that if your staining them, then just fill with flexible filler. easy fill would crack with movement.
I have never done my next suggestion but just a thought....maybe a flexible floor tile adhesive that dries white that would then stain. but would try a section first incase it dont stain well.

yeah i think you might be on to something like a flexible adhesive. many thanks
