Grain Filler under White Shellac

[Michael Q]

I have made a dining table with jarrah ply and 150mm solid jarrah sides and ends, legs etc. The solid timber is smooth and requires little or no filling but the ply requires a lot more sanding and or grain filling to have an overall silky smooth surface. I am concerned I may sand back too much and ruin the whole project

My plan was to finish with U-Beaut White Shellac to show off the beautiful colours of both timbers.

I was thinking of using U-Beaut white shellac and talc powder as the grain filler but am concerned that it may change the colour of the ply where the grain needs the filling most.

I really do need guidance here.

To date I have not found this a problem. The shellac/talc filler leaves a silky smooth surface after sanding and the talc filler is not visible under subsequent coats of shellac.
But experiment on a scrap. If the sanding sealer appears pale you can add a little powdered pigment, such as red oxide, to the mix. Again, experiment on a scrap.
And I'd be using U-Beaut Hard Shellac for a table top. White shellac is not durable enough for this.

Thanks Brian, I will have a play around.
