Thread: Fillers - timber mate/builder's bog

The best.

Selleys Plastibond 400g Heavy Duty Bog - Bunnings Australia

Builder's bog works, but it's a very coarse texture so it might not look right. I have used black paste dye from Solid Solutions with it successfully, but it does decrease the working/cure time, I assume powders would work fine.

EDIT: Put some small screws in the edge sticking out to give the filler extra stuff to hold on to if it's a big fill.

Timbermate makes a few products... If it's the water-based filler and you say it's going to extend into a right angle I wouldn't trust it to work well.

Builders bog is much stronger but have no idea if you can add a dye to make it black.


You don't want to use epoxy because you don't want to wait for it to cure...


Use 5 minute epoxy then.

YMMV

I have never used builders bog type of product before so I suppose I should give it a go

What makes this selleys plastibond better than the others?

Is builder's bog basically a plastic? Is the 2 part mix sort of like epoxy or what is it based on?

In regards to 5min epoxy - the stuff I have sets in 5mins but then 24 hours later it shrinks a little bit - has that been your experience?

I believe the bog-type fillers are styrene based. The ones for auto body work are often a finer texture but do take a bit longer to set (maybe an hour or 2 instead of 20-30 mins)

For smallish stuff with 5 minute, we used to build little dams with plasticine so you could overfill and counter the shrinkage. Or just do a second fill after the first one shrinks

Pick it up and compare its weight to the other similar types of Bog and you will feel the difference straight away .
A more heavy more solid setting Bog .
Costs more $ per KG usually .
Builders Bog is light weight fluff compared to it .
I only ever tried the cheaper Builders Bog once and went straight back to PlastiBond without finishing the tin .
Bogged a few cars over the years with the car body fillers and never came across a more solid bog compared to PB there either.
Been using it for 44 years now and I haven't tried comparing others to it for a long time . Maybe 25 to 30 years.
I use other types of bog as well for different uses . Agnews water putty is one . For restoration I sometimes use solid coloured shellac sticks and coloured hardened wax sticks that I make up.

Ive only ever used timbermate wood filler
EARL’S TIMBERMATE(R) – Timbermate Group

Do you use that? When would you choose that vs their water putty product?

Can the agnews water putty be coloured?

To answer the second part of your question
Yes you can use oxides to colour the builders bog / Plastibond etc Flooring contractors use it often to fill the large holes in feature grade floors prior to finishing

I did try Timbermate once . I didn't use it all and I think I eventually threw it out. It worked but I'm not into buying different coloured containers of filler to cover my needs. Agnews is a light yellow colour and my Oxide powder range is close by . With the oxide colours I can coulour Agnews for what ever I need. Colour Plastibond . Make up water based coloured washes or paints. And tint shellac. I quite often add PVA or Titebond to Agnews as well if I feel it needs it.

Water putty like Agnews is ok when I have a lot to fill and am not in a hurry. Put it on and come back to finishing it the next day depending on the finish type Im using. if its spirit or oil based then its go to be dry. If its water based then i can continue on after after and hour when its gone hard but not totally dry. Plastibond I use when I am in a hurry. It dries fast. And its usually when I'm filling on top of a job with a finished polished surface.

A typical Ag putty job may be a half a tea cup to a full coffee mugs worth on something like a whole lot of splits and knots on the under side of a table .

Typical PB job would be a teaspoon to a table spoons worth, colour matched . Quite often in between coats on a project I'm polishing or about to polish.

5 or 30 minute Araldite and very very fine coffee grounds.

Thanks all

Does the 5/30min araldite shrink?

I have trojan fibreglass 5min epoxy and it sets quick but you cant sand straight away as it will shrink the next day!

I have had some success with mixing a paste of Timbermate and PVA to repair arrises. However, it's still relatively soft/crumbly (about the same as stabilised spalted timber) so I wouldn't recommend it for anywhere that sees handling or occasional knocks.

I prefer to splice in a new bit of timber, but have often used builders bog if the finish coat is going ot be paint. It will take dyes & oxides, but I've never found the result to be pleasing.

On t'other hand, in my wood turnings I'm a big advocate for filling knots, gum veins, borer lines and similar "signs of character" with Araldite & coffee grinds. Although some may cringe to hear it, I've also successfully used instant coffee at times!

Builders Bog doesn't - or shouldn't - shrink, but Araldite in large enough sections does. In either case I always fill above and beyond what's needed, then shape back to final form when fully cured. 'Tis far easier to get a consistent result that way.

I quite like the auto body fillers. You can get ones that have some flex, that are intended for repairing plastic panels, predominantly bumpers. It sets hard, but it won’t crack when it flexes. It’s a two-part mix, and hardens very fast. I use it all the time, mostly for patching up templates. Especially curved ones, it’s really easy to get a wobbly section due to over it on the bandsaw or inaccurate sanding. Auto bog is a quick fix and saves having to remake the template.

The plastic auto body repair bog probably wouldn’t work for an edge though.
Either way, I’d probably just take Auscab’s advice. He know things!

Question about agnew's water putty - can I mix a match and put it in an air tight container and leave wet? Because thats basically what timbermate wood filler is right?
