    Default Sanding sealer for defects?

    G'day all,

    I'm trying to work out the best way to seal and fill various minor defects in some recycled Messmate, but I'm not sure if the usual sanding sealer is the best option. The final finish will be Shellac and I'm planning to use the same shellac as a sanding sealer, no issue there, but the larger defects are proving troublesome.

    The timber is originally from a pier and has some visible weather checking and greying after jointing, which looks very nice I think. The problem is that the checking runs up to 3-4mm deep and perhaps 1mm wide at some points. I've tried four coats of Shellac based sealer, but I could be here all week filling them this way.

    Might I try using one or two coat of sealer, filling the defects with epoxy or similar, then sanding and finishing with Shellac? I don't have any talc to make a thicker sealer, would this be a more suitable option? Perhaps there's another product that might do a better job? I'd like to make the filler clear rather than opaque if possible/practical.

    Any other suggestions are welcome.

    Dave.

    I make up a mix of Plaster of Paris with brick colour to colour match timber fill the offending area the when dry rub excess of with a nylon pad or very light rub with 150 paper and apply film of boiled linseed oil leave for a time till touch dry and shellac over the top of that.

    Give it go it's cheap and works. Failing that get some colour wax sticks and melt into gaps the scrape of excess with a scraper and continue on.


    Cheers

    Why not just use the product made for such jobs - wood filler?

    "Timbermate" probabl;y your best bet.

    Just follow the system-

    Sealer for sealing _ (check previous threads)
    Filler for filling
    stain for staining
    finishes for finishing

    You will allway have problems if you try and make up your own system, more often it will not work as well as it can.

    Wax sticks, or bees wax and stain both work quite well. Timbermate has its place also, depends on preference.

    Thanks folks.

    I don't want to use the timbermate or similar products if I can help it, I'd much rather a clear filler. I use timbermate for the unsightly blemishes like nail holes and such and it works very well, but the weather checking looks quite good. It very much gives the impression if both age and depth.

    As a test I took a test peice and flooded it with Hard Burnishing Oil, then waxed and buffed it up. Looks awesome, but I still need to fill the cracks.

    chowcini, I've just put some Techniglue in a test peice yesterday evening to try it out. I had some material with some very deep gum vein, maybe 10-15mm deep. If it works there it will work well anywhere! I'd only ever used it as a glue in the past and I have the impression is dried a little opaque. We'll see this evening.

    I use polyester resin when I don't want colour, its on the dark side of clear but seems to work well as a hole filler.

    That sounds promising, do you have a brand/product name? Polyester resin covers quite a bit of ground generically.

    I use norglass casting resin, which is a polyester resin. It dries water clear.

    That looks like exactly what I need, where to buy it?

    Well, I get mine at my local hardware, which is a Mitre 10. You'll find it wherever they keep fibreglass resins and the like. Don't forget to buy a bottle of catalyst, which doesn't usually come with it.

    I'd lean towards a glue like epoxy (say) over filling it with wax. a wax won't stop the crack from continuing should it be so inclined. for colours I've just been using cement pigments of late. just powder. with a little stick just drop in a bit of it at a time while mixing until the colours good.

    I tried just about everything to fill flaws in myrtle burl vereer I use on jewellery boxes, last resort tried fibreglass resin ,mixed in redgum sander dust and then added the catalyst. Spread it over the problem area and sanded back, filled every nook and cranny, gave a beautiful finish.

    It does fill well, and if you don't plug any holes underneath it also does a good job of filling every little nook and cranny on the work bench and floor.
