hello

i have used the clear cast resin but now need to mix it with this glow powdr i have, which i did but you cant sand this resin nice, is there a resin that i can sand so that it is level with the channel in the wood i am filling with and polishes clear again ?

thanks

Hi John, what resin are you currently using?  For filling a channel in wood, typically our GlassCast Clear Epoxy Surface Resin is a perfect choice.  If you look at this picture, we literally poured the resin into a mixing bucket and then easily shaped the resin with sandpaper before polishing back to a gloss:



Hopefully you should be able to level off the resin in your situation then bring back to a high gloss relatively easily.  You may find you need to leave it a bit longer to cure before sanding if you are having difficulties.

yeah it is clear cast epoxy resin but i sanded it up to grit 220 do i need to go a lot finer

thanks

Hi John. You'll need to work to much finer grades of wet/dry abrasive paper. To remove the light scratches created by the 240grit, you would need to use a 400grit and then an 800grit followed by a 1000-1200grit before switching to a cutting compound to bring up the final gloss appearance. One tip is to change the water between each stage to avoid picking up any loose grit from the previous stages.

ok thanks foir that but wouldn't the cutting compound affect the surrounding wood, maybe it would stain the wood

thanks

It shouldn't cause any permanent marking on the wood itself. Any contaminants would usually wash off.

ok thanks a lot ill give it a go

This partly answered a question I had too. I’ve sanded cast acrylic rods (bought as solid, not cast myself) to high gloss before using 1600 grit paper after cutting. With “self cast” I’ve seen recommendations to “glaze” finished articles with a thin coat of resin (which is good advice for complex intricate surfaces) but I was wondering if that was necessary or if 1600 grit would get something like on a surface that is mostly “flat”, or at least, smooth?

Do you have any advice sheets (videos?) on how to achieve the best gloss finish with your various materials? With the range of options you have for clear finishes I’m sure a lot of your customers would find it helpful (me for one)!

We don't have any videos specifically on how to use sand paper and polish to get a smooth finish.  It is covered in a couple of our other videos especially our video on How to Cover Existing Parts in Carbon Fibre - XCR Skinning Tutorial which shows the materials needed and steps needed to get a smooth finish in detail.

It wasn’t really use of sandpaper I was thinking of...more selection of materials. For instance I didn’t realise until I read it here that one of the clear resins remains tacky if exposed rather than enclosed completely in a mould. I will check the other video out that you mentioned though.
