Is ts55 the right tool?

[Kokako]

I need to remove some particle board sub flooring.. The problem is the particle board runs under the internal and external walls... Ugg...

Anyway, my plan was to cut as close the walls as possible to remove the rubbish, then insert shims under the walls before I lay new ply...

Is a ts55 the best tool for this? Would I need to use the track or not? I have no Festool experience, but it looks very tempting.

Thanks in advance.

The TS55R is actually the best tool - the "R" goes a little bit closer.

No track, just plunge and follow the wall ... remembering to limit the plunge depth !!!  [smile]

Welcome to the FOG!

Yes. TS55R is the right tool. Bosch makes good blades for wood with occasional nails named Construct wood blades. You'll need 160mm diameter blade with 20mm arbor (hole).

Victor: Is the bosh blade specifically for the ts55r or just happens to fit?

Anyone done this job before?

Any suggestions on how to remove sections of the particle board that are under the walls to make room for the shims?

Thanks very much for the info!

Haven't done this, but interesting very short section of it happening in this video ...



... among other stuff.

Just fit it.

Hi,I think you should leave the stuff under the wall.
You will find nails and other "stuff" under the wall,
that you cannot get out.
I think if you cut the floor as tight to to wall as you can,then
block under the wall,leaving half of the block out from the wall,
you can support the new floor at the wall.

If you are sure you want to remove that material,then
run a chisel into the flooring under the wall,breaking it in
small pieces (1/2)inch ,and pull them out with a pair of pliers.
After its cut with a saw.

I hope this helps,
Chuck

I had to do it this week on a Bathroom refurbishment. I left about 2" (50mm) of the particle board sticking out from under the wall and used off-cuts of the new plywood floor(screwed and glued) to the underside of the bit sticking out, then screwed into them to fix the new plywood down.

Admittedly, I used a TS55 (not the R) to do the job, and did it without the rail. Laid the new tiled floor today!

TS did the job a treat! BTW, look out for old nails or use an old blade....... [sad]

Thanks for all the info guys!

What about the possibility of the walls shifting/settling vs. the new ply? I posted this same query at another forum and one bloke thought that the particle board, being less stable than ply, might shift the walls in relation to the new floor...

I am also doing a bathroom that is planned to have tile, so I'm keen to hear any thoughts on this...

Hi Kokako,

Welcome to the FOG!  [smile]

If you are going to run the saw right up against the wall you may also want to get item # 491 750 Cover Plate. This covers the hole in the side housing which improves the DC and keeps dust from blowing out the onto the wall. It also has base runner type material on it to make it slide well and protect the wall.

I don't think it will settle
I worry that you cannot get all the debris out from under the wall & have a heck of a time putting new material back under.
Just my .02 cents

Ps I am doing the same project this summer. Bathroom

Kokado,

You have'nt said what type of constuction the internal walls are. You should be able to pull out the existing particle board from under the outide wall. It is not likely that it goes into the wall very far(20mm or so I would think.....?????!!!!!)

On the job I am working on, the internal walls are a lightweight thermal block that has been rendered and plastered. The house was built in the late 60's and so I think any potential movement will have occurred already and is not likely to move now. By screwing and gluing plywood down to replace the particle board, you are increasing the strength of the floor rather than weakening it.

Tim: it's just stick framing. Actually in the bathroom, there was a leak under the tub and the particle board completely disintegrated... The bit there at the wall just crumbles away... As far as I can see the Particle board goes all the way under on the external walls.

Did you run screws into the PB you left sticking out?

 

[Kev]

Whatever you finally do with the particle board that remains, I'd look to sealing it with something to try to avoid further disintegration.

Kokado,

Yes, I screwed and glued the plywood brace to the underside of the particle board, then screwed and glued the plywood floor to it.
I have had to do this type of thing on many occasions as this type of particle board is still used extensively in the UK.

I normally seal the complete new floor with a proprietory sealer prior to laying the tile adhesive and tiles. Although there is more movement in particle board than plywood, the small sections of particle board that remain, have never been a problem on the occasions that I have had to do what I described above.

This bathroom floor was replaced as I described-

If your only job for the TS55 is the floor removal I'd say it is way overkill. Yes it will work just fine but so will a Skillsaw. Yes you will not get quite as close to the wall, but who cares. Leave the material under the walls. You do not want that headache to worry about. Put in your new plywood subfloor butted to the old remaining boarder and be done. I'm sure can come very close to the thickness of the old flooring. Save your money for another part of the project.

 

[Distinctive Interiors]

Chuck is quite right!

The TS55 has far more uses than floor removal and to buy one just for this type of work is excessive.

I use both my TS55 and TS75 for all sorts of material cutting. This being a very small part!

Nope, I'm not that decadent as to buy one just for ripping out rotten Particle board...!

I am in the market for a circ saw, and as I will need to cut the new ply to fit in the non-standard spaces, plus flooring  and 100 other things, I thought a track saw would be the way to go...

How do you guys rate the TS-55/75 at cutting things like corrugate roofing and concrete board?

I can't comment of corrugated roofing, but the blades offered aren't really designed to cut concrete board.  I have used older blades to accomplish this task in the past where I had to cut a piece inside a clients home.  There was no dust flying around (that concrete dust is nasty) and there was plenty of power to accomplish the task.  Again, I wouldn't use a fresh blade, the concrete board will quickly dull it.

I am never one to discourage someone from buying a Festool tool, but..If this is a one-time job, maybe a toe-kick saw will work? honestly like $50 from Harbor freight. But...If you have future uses for the TS55r, by all means invest in that. It's one sweet saw and would work well for you for this project. Where it really tends to shine is ripping sheet goods with ease.
