Project Overview

If you’re planning to resurface your laminate benchtop, it’s important to make sure your surface is nice and flat. Water can often damage the chipboard underneath the laminate causing it to swell and develop unsightly bulges or splitting. This video shows you how to get rid of that damage and patch the laminate to look good as new. Continue to step-by-step instructions

Step by Step Instructions

1 Cut around the damaged area of the laminate
2 Scrape off the damaged laminate and sand back the chipboard
3 Patch the hole with builder’s bog
4 Scrape off the excess builder’s bog and sand it back to be smooth and level
  • Step 1. Cut around the damaged area of the laminate

    If you’re planning to resurface your laminate benchtop, you need to make sure the surface is flat by removing any damaged or raised areas first. Start by marking out the damaged area with your marker and ruler. Make sure you have your safety gear on (gloves, mask, goggles, ear protection), then use your grinder to cut around the damaged section of laminate.
  • Step 2. Scrape off the damaged laminate and sand back the chipboard

    Now use your paint scraper to get in under the damaged laminate and lift it off the chipboard. Once the laminate is removed, use a course-grain sand paper to flatten down the chipboard. Then give it a quick wipe with a cloth to get rid of any loose material.
  • Step 3. Patch the hole with builder’s bog

    Mix up a batch of builder’s bog on your mixing plate. When it’s ready to use, it should be a light pink colour. Then apply it to the gap in your laminate with a wide-edge paint scraper. Make sure you spread it on thick. You’ll be sanding this back to bench level, to make that job easier clean off any excess bog before it sets.
  • Step 4. Scrape off the excess builder’s bog and sand it back to be smooth and level

    Once the bog is dry and had time to properly cure, use a chisel and scraper to gently remove any excess. Then roughly sand the bog back to bench level using 120-grit sandpaper. When it’s level with the bench, use the finer-grade 240-grit sandpaper to smooth back the surface. Give it a light sweep with your dust brush and the bench surface is ready for painting.
