Materials and Tools List

Tools

  • A circular saw with three blades: general purpose wood, metal ($5) and diamond masonry ($20). The diamond masonry blade costs more, but last longer and cuts quickly.
  • A hammer
  • 2'-3' level. A long level is worth is it. You can find a long, inexpensive aluminum level at Home Depot if you do not already have one.
  • Grinder (optional). You can use the grinder to cut rebar, wire, and concrete block. You can buy an inexpensive grinder for about $25, which will save you time from not having to change blades on your circular saw.
  • A chalk line ( <$10).
  • A 1/4" x 1/4" notched tile trowel for the
    mortar base.
  • Goggles and a dust mask
  • A mixing tub (<$15)
  • A hoe for mixing ($10 for a cheap one, $20 for a good one)
  • A square edged transfer shovel ($20).
  • A Tamper ($20 or build one from a square of plywood and a 2x4).
  • Concrete mixer (optional). Rent one from Home Depot.
  • Tile saw (optional). You can get by with a diamond blade and a circular saw. If you have complicated tile, brick or stone trim or finish, you can either rent a tile saw, or purchase a small, but functional tile saw from Home Depot for less than $100.
  • Ratchetting cargo straps (optional). About $10 at WalMart. Used to hold the hearth form in place while it is curing.

Hints and Tips

Check Home Depot for Vermiculite. You might find it in their garden center. If not, try pool supply (chemicals, etc.) and agriculture supply (fertilizer, etc.) stores. The 8 cu ft bag costs less than buying lots of small bags from a nursery.
