a unwanted floor cavity in the bathroom - what materials required?

[tutsiwarrior]

hello folks...I've got a wood door frame in my upstairs bathroom and a joint between the vertical and horizontal components has rotted out resulting in about a 2" x 2" cavity that needs to be filled and sealed...the water from showering and splashing about ends up on the floor in my kitchen below...

 

thought about using a grout but I've only seen grout available in 50kg bags that needs to be carefully mixed and cured (non shrink) when applied in an industrial application for big pumps/compressors after setting and alignment between base plate and foundation and I only need a little bit then sealed with silicon on top to give a non permeable surface...

 

anyone got any suggestions like for a little tub of something suitable and ready mixed for the purpose available at homepro and etc? total volume required would be like 2" x 2" x 4"...

 

thanx in advance...

Any chance of a picture? It would be really useful so we can see what you are describing.

 

Thank you!

aw hell...thought that I could get away without a picture (to paraphrase Stother Martin as the work camp boss in Cool Hand Luke 'what we gots heah...is a failyuh...to visualise...') but I fully agree blackcab, if the technology is there then use it although I hate fiddling with gadgets and their stupid apps...

looks like someone's been in there with the silicon already trine to sort things out, probably the step daughter's boyfriend who lives here and doesn't work and eats the rice that I pay for...extra work as that will havta be excavated...

thanks for the suggestion but epoxy resin sounds a bit extreme, I useta patch surfboards when I was a kid and resin is hard to work with after you add the catalyst (gotta be quick) and permanent...I dribbled some on the floor of our back terrace and me dad smashed me nut 'I tole you wait 'till I got home ye little eedjit...' etc...the usual failure to communicate...if somehow the resin used the same path as the bath water to get to my kitchen below I'd have a real mess...could let it set and harden on the kitchen walls and get the kids to decorate it with psychedelic patterns, I suppose...

You may be thinking polyester resin.  If it stank to high heaven, that was polyester.  It sets up real fast, while epoxy takes a while and doesn't smell nearly as bad. 

 

In either case, I'd suggest mixing some sawdust or wood powder (sold for boat building- look it up) into the mix and you'll have a putty the consistency of peanut butter.  It may be overkill, but it will outlast the zombies when the apocalypse happens.

 

Just to give you some ideas:

Edit:  I always keep some alcohol around for cleaning up any epoxy spills before it sets.  Rubbing alcohol works, but methanol or ethanol are better.  After it sets, it's time for a hammer and chisel...

or some dynamite (my emphasis)...

 

I believe that it was epoxy resin that I was using to patch surfboard dings in the early 60s and it smelled real good and when I'd take receipt of a new board I'd lay with it in the garden with my nose up against the lamination between the foam and the fin (this was way before removable fin systems and the fins were huge) and breathe deeply and think about a surfing Xanadu...

 

thanks for the youtube info...I'll check it out...

Clear evidence of past termite damage, maybe check that first.

 

I would remove the wood threshold for starters and start again making a proper threshold either from sand and cement or a deeper section timber.

Because its eaten into the jamb of the frame, simply pouring to fill a hole will still leave a hole.

Lots of small tub apications in the stores, mostly concerned with concrete repair, watwr plugs, sika etc is a start for small tubs of hand mixed.

don't think it's termites or the same damage would appear everywhere we got wood door frames...looks to me like a moisture accumulation from the bathroom...

 

ideally I would replace the entire door frame, pull up the first course of adjacent tiles and install a moisture barrier but presently can't be arsed to fool with it...just wanna keep the bath water out of my kitchen down below...

 

I'll look out for the products that you suggest pre mixed in small tubs at home pro and etc, that and some silicon should do the trick...

 

'hey tutsi! ye gots wattah in yer kitchen again!' I don't wanna know, just wanna pour another vodka and watch my favorite porn star Mia Lina in action on the internet...a westerner in decline and worthless in rural SE Asia...
