Introduction: Curved Concrete Bench
Step 1: Tool List and Materials Needed for This Project
- Carpenter's level (All work surface must be leveled properly before starting work)
- Drill with mixer head
- Zwaluw High Tack
- A Formica/HPL covered wood plate (iv used approx 60" x 80" or 2m x 1.5m)
- A lot of supporting wooden - made easily with
DEWALT DW777 Compound Cross Cut Mitre Saw (makes the making of the supporting wooden MUCH EASIER)
- Sandpaper 80-140-240 GRIT
- Fine Brush
- Concrete sealer
- some screws
- Work Gloves
- Disposable gloves
- Dremel tool
- 2 PVC Pipes (for the legs)
- 6mm Steel wire
- Polystyrene board 20mm thick
- some Clamps
- Steel Brush
- White cement bag
- Fine Gravel bag
- some old buckets
- Gas Burner
- Duck Tape
- Grindstone angle
Step 2: Sketch & Calculations
Step 3: Placing Up Wooden Support
Place the supporting wood without glue.
Glue it only after you have checked the correct position on "dry mode"
Step 4: Finish Reinforcement
Reinforcement finalized by screws, and some silicone adhesive
Step 5: Adding the Frame and Styrofoam Blocks
Step 6: Mixing the Concrete
Start by using a shovel to mix well the mixture, and only than use the electric drill for the final mixing
Step 7: Pouring the Concrete
Gently pour the concrete to the mold with a small spatula
Step 8: Attaching the P.V.C Pipes
Carefully cut the styrofoam to flat level as the concrete and clean the area from concrete leftovers and place the P.V.C tubes in the exact sitings were the iron frame is protruding.
secure it with silicone and than pour concrete inside.
Step 9: Removing the Styrofoam
allso, I did make some holes with screwdriver in the styrofoam, resulting increase in the acetone etching speed.
Step 10: Unscrewing
Step 11: Brushing, Sanding, Cleaning
Note: The Chamfer is made by starting with dremel sanding drum and than polished by hand with fine sandpaper.
Step 12: Concrete Sealer
