This means that the coating near the edges will wear more quickly.įor a smooth, even application of the paint or coating, a fillet is a better option. Usually less time effective unless a round mill is already being used to mill complex, curved surfacesįillets require specific size tools to produce different fillet sizes.ĭue to the sharpness of chamfer corners, paint or protective coatings will draw back from the edge. If the part is being milled, the cost will be equal to that of a chamfer Less expensive if the part is being machined manually Comparison Between Chamfer and Fillet Edges Dip the float into the water frequently for the best results. Whether the concrete is poured directly into the forms from the ready mix truck or is transported there via wheelbarrow or pump, the concrete should be placed. Portland cement, water, and aggregate comprise most of the composite material known as concrete (gravel, sand, or rock). Start each stroke at the upper, chamfered edge and work downward. Use small, radius strokes with the float to finish the face of the porch where the form was removed. Dip a rubber float used for finishing plaster into the water. Slide the form one way and lift it up at the same time to remove it without damaging the face or edge of the porch.ĥ. Tap one end of the form several times with the hammer to release it from the edge of the concrete porch. Pull the nails out of the form stakes, using the claw end of a hammer. Allow the concrete to cure for two hours or until a light swipe with the steel trowel does not affect the surface's finish.Ĥ. This time, use light pressure on the tool and create a uniform, chamfered edge. Repeat the above step using the edging tool. Use the inner face of the form as a guide and work the tool forward and backward, using long strokes.ģ. Grip the handle of the tool and insert the lower edge into the seam between the edge of the concrete and the form. A square foot of conventional concrete weighs about 150 pounds, and a typical concrete project may require hundreds to thousands of square feet of concrete to be placed at one time. Set the entire trowel down on to the Pan and slide. Panning- Once again, keep the Finish Blades bolted to the trowel. You will be able to use both sides of the Finish Blades after rotating them 180 degrees. Start by chamfering the edges of the porch with the edging tool to embed any gravel below the finished surface. Forming Concrete With Plastic Forms Time: 06:11 Forming concrete with plastic forms is an easy way to do curved radius patios, walkways, and other concrete slabs. Once you have effectively floated the concrete, just slide the Float Blades off, and run your Finish Blades, starting with a slight pitch. Typically, this takes about 20 to 30 minutes after the concrete is poured and troweled with a wooden float.Ģ. Allow the concrete to cure until any water on the surface dissipates.
