Rustic ash is a natural timber benchtop with true character, featuring visible knots, gum veins and pockets making every piece truly unique.

These are naturally occurring, giving the benchtop character, but to get the most out of the surface, we have put together a step-by-step guide, as it’s our recommendation to fill these features in your benchtop.

So, what will you need? We have listed all the tools, equipment and products you will need to effectively seal this benchtop below:

  1. Orbital sander and belt sander
  2. Measuring cup
  3. Protective glasses, gloves, mask and ear protection
  4. 63mm paint brush
  5. Paint stirrer
  6. Rags
  7. Vacuum (optional)
  8. Sandpaper 100 grit, 120 grit, 240 grit & 1200 grit (optional)
  9. Kaboodle hardwax oil
  10. Paint can opener
  11. Protite clear Casting Resin
  12. Protite resin Catalyst

step 1: identify any spots that require filling

step 2: give the resin a good stir for about one minute

step 3: pour the resin into a measuring cup (use 150ml)

step 4: add the drops of catalyst to the resin as per the ratio instructed on the resin tin

step 5: stir the resin and catalyst together until mixed well

step 6: tape the underside of the benchtop where there were holes going all the way through the timber, as the resin might sink through

step 7: slowly pour the resin into the holes making sure to overfill, you can sand it flat once it dries

step 8: give the resin 24 hours to dry

step 9: once dry, sand the resin flat with a belt sander using 100 grit sand paper and follow with an orbital sander using 180mm and 240mm grit sanding discs

step 10: sand both sides of the benchtop using 120, 240 and 1200 grit sandpaper

step 11: use a vacuum to clean up all excess dust in-between coats

step 12: in this example, three coats were applied to the top and two coats were applied to the underside with light sanding in between coats

step 13: the hardwax Oil was applied with a 63mm Monarch brush, allowing 24hrs for each coat to dry

step 14: Once installed, give the benchtop a wipe down using all-purpose cleaner and seal edges against the wall with silicone
