Sanding Resin

G'day mates,

I filled a knot and some cracks on a walnut table top with Digger's Casting Resin. Prior to which the top has been finely planed.

I would like to sand the top starting at 400 grit prior to finishing it with the Sam Maloof recipe (higher grit sanding between coats) followed by U-beaut's traditional wax.

Which grit should I start from and when do you stop for the resin? Do you wet sand?

I have never sanded resin before and will highly appreciate any guidance provided.

Cheers :2tsup:

You can sand the resin basically just like timber. You can also plane the bigger lumps off with fine cuts, but I tend to just sand to avoid chipping. It sands to an opaque finish, but turns clear on applying the final finish.

G'day Neil,

Thanks for the advice. I actually sanded the resin I tested with a piece of scrap. It became so scratched, I was like "What the....".

So, I figure I take a step back and ask for some help. Now, back to the grits.

Cheers mate,

Once the wood/resin has been sanded, I usually go a few more grits down on just the resin area.

eg. I may stop sanding the wood at 600 grit, but take the resined area down to 1200.

Purely to reduce the size of the scratches, as sometimes I miss a "big 'un" and it shows through the finish. :rolleyes:

Good stuff mate. Definitely take your advice on that.

The 1st 2 layers for the table's legs, I did a 1:1 Sam Maloof & Turp combo, just so it was thinned down for better absorption. Between each layer is sanding at 800 & 1200 respectively.

The next 3 layers of oil will be just the Sam Maloof finish, sanding with higher grits.

The walnut top is sanded to 400 now. I am planning to give it 3 layers of 1:1 Sam Maloof & Turp combo, sanding at 600, 800 and 1000. Then 3 layers of Sam Maloof, again sanding with higher grits.

Then top everything with a few layers of Ubeaut's wax.

We'll see how all that goes. Thanks again.

Cheers,
