Fabric Formed Concrete Fire Table


After the fabric is stretched over the central disc, it is sucked down with a shop vac, creating a smooth transition down to the burner.

What You’ll Need

Step 1 – Air Hole

  • A vacuum cleaner will be hooked up to the underside of the baseboard, so an air hole needs to be drilled to attach the vacuum.
  • Drill a 1/2″ hole close to the edge of the disc that is creating the bulge in the fabric.
  • Mount the vacuum to this hole, using gasket rubber to create an air-tight seal.
  • The form should be suspended on saw horses, making it possible to attach the vacuum hose.

Step 2 – Vacuum Hookup

  • When the vacuum is attached to the form, it’s ready to turn on.
  • When the vacuum is turned on, it will suck the fabric down, creating a smooth transition up over the 4″-thick disc.
  • The vacuum needs to run for a few hours, throughout casting and well into the curing process.
  • Blow any debris out of the form with compressed air and clean the inside with denatured alcohol.
  • Any additional Decorative Details can be placed at this time.
