Sanding sealer
« on: July 21, 2009, 06:55:12 pm »

Come on all you knowledgeable types, how do you clean brushes after using sanding sealer? I tried all sorts the other day, eventually having to throw the brush away! With the amount of wood still to be treated on my current project, this could prove somewhat expensive. Any ideas will be gratefully received.

Hi,

What sealer is it- Cellulose, Organic Compound?

What did you use to try and clean it?

It sounds like you are using the Cellulose Sanding Sealer, so Cellulose Thinners will clean the brush.
As these thinners tend to be expensive and only used on Sanding Sealer I use a rag to apply or even a set of brushes from the pound shop and throw away after each use.

If it's cellulose (smells like peardrops) you can also use acetone, this is also good for cleaning up after using polyester resin

Easier and cheaper solution:

 - keep a couple of good, soft brushes for all the dope family (dope, sanding sealer and banana oil)
 use the brush,
 squeeze it out with your fingers and lay it aside - it will go hard, but there is very little dope still in the bristles
Next time you use it put it in the can of dope and the bristles will be soft again in seconds

Viola - you are using the solvent in the dope to soften the bristles!

Hi Folks,
My thanks to you all for your suggestions, perhaps I will now be able to get on with the "woodwork" parts of my boat, without breaking the bank buying new brushes all the time! :-))

Hi Danny
On a big sanding sealer job time is your enemy, so I prepare for the job this way

Have three brushes at hand and a little cellulose thinners ( if using cellulose type sealer..most probable u r )

When I feel the first brush is going off I put in into the the thinners then use the second one. When the second one goes off I switch to the third brush. Put the second one in the thinners, take out the first one and wipe ready to use. Continue the cycle till job done.

When completely finished the job and all brushes cleaned with thinners. A soapy wash under the tap and a wipe clean with a paper towel. Store them in a clean plastic bag.

Resurrecting an old topic here!


1. Is Cellulose Sanding Sealer the same as Spirit Sanding Sealer?

2. I have a 'die cut' sheet of ply, is there any 'mileage' is sealing & sanding the wood before building?

Not usually ,
`Spirit sanding sealer` is usually shellac based dissolved in various alcohol solvents (plus the filler additives)
Cellulose is usually nitrocellulose or cellulose acetate based dissolved in acetate and ketone solvents sometimes with alcohols  xylene or toluene added plus the filler additives

And if you are unlucky, you get a great 'high' and then your heart gives out like with a few kids who tried glue sniffing. Cellulose smells lovely but isn't good for you  :((

Its not that bad...neither of them can do very much harm to anyone


The alcohol based ones...shellac....used to make sweets shiny and alcohol as the solvent you can drink the fillers are allowed in tablets...but its not very waterproof


Cellulose, as long as its a good solvent blend to dissolve the cellulose powder ( with no toluene ( banned ) xylene or methanol ) we dont have any of them in ours....its virtually the same as the spray on plaster from chemists shops , so allowed to be sold for spraying onto skin even, ours due to lack of the toluene and xylene doesn't need a toxic symbol.


And neither should ( unlike waterbased... so called `safe` products....) contain `glycol ether esters` ( a group that many solvents in t group cause cancer ) .waterbased...so called....`safe` products do contain these solvents to make them work at lower temperatures
