Product Detail:- Re-usable Edge Form Liner to create a detailed edge on concrete.
- "Chiseled Granite Rough Rock" edge detail, 3" tall. Very similar to our 3" Rough Rock edge face, with a slight difference in the center of the form liner where it forms more of a point- The edge of the finished concrete has more of the appearance that the 'Rock' edge was chipped out from above and below, creating a horizontal ridge running in the middle of the edge.
- Create a rock edge on concrete countertops, pools, steps, etc.
- Made of extremely durable polyurethane that can flex and stay strong.
- Can be used in pre-cast or poured in place concrete work.
- Cut to length easily with a utility knife or chop saw. Join cut pieces using silicone.
- Fast and easy to place in a mold, and quick to clean after use.
- Good for hundreds of uses- Actually gets better with each use as they 'season'.
Product Specifications:- Measurements: 90"L x 3"H.
- Rough Rock edge depth varies +/- 1" as it contours with the 'rough' surface of the rock face.
- *Occasional imperfections may be
present on the Edge Form Liners, and can be removed or altered using a
sharp utility knife, or a very abrasive sand paper or resin-bound
grinding discs.
Mold Setup:- Edge
Form Liners can be curved to form a radius edge. If the Edge Form
Liner begins to ripple and distort, then the radius is too tight, so you
will need to make the curve radius larger to ensure a smooth,
consistent edge detail.
- Edge Form Liners can be cut to fit your
form. Cut using a SHARP razor knife, or with a chop saw. Liners can be
cut straight, or mitered at angles so they fit tightly in your form.
- Place
Edge Form Liner in your form and either silicone in place, nail with a
small brad finish nailer, or screw through the backing form into the
Edge Form Liner.
- For most applications (Precast), run a silicone
a bead across the bottom edge of the Edge Form Liner, up any corners,
and across any joined together seams, to create a water-tight seal.
- Use
of a Rubber Safe form release is recommended, but usually not
necessary. Form release generally will create a smoother finish on the
concrete, less air pockets in the concrete edge, and easier to clean the
Edge Form Liners when finished.
- Vibrate concrete well (either
vibrating the concrete, or rapidly tapping the edges of the forms with a
hammer or palm sander), or use your fingers to compact the concrete
against the Form Liner to remove as many air pocket voids as possible.
Edge Liner Removal:- After the concrete is sufficiently set up (typically 2-3 days for precast), remove the Edge Form Liner.
- If
the Edge Form Liner needs to be removed before the concrete is cured
(usually only when using on cast in place concrete, such as steps or
pool decks), make sure to remove edge slowly, evenly pulling the liner
'out' away from the concrete.
- Removal is simple- start on one end, and slowly peel the Form Liner away from the concrete.
- Concrete
usually will have small 'bumps' which can be sanded off with a 200 grit
sandpaper. These bumps tend to disappear the more the Edge Form Liner
is used, as it becomes seasoned.
- Fill any air pocket voids with a Concrete Slurry Mix.
Edge Liner Care:- Clean
with a stiff brush and water after each use. Any silicone left on the
forms should be peeled or scraped off (the sooner the easier to remove).
Any hardened concrete and difficult to remove silicone can usually be
removed using a wire brush.
- Muriatic Acid can be used to clean
of cement residue from the Edge Form Liners in a 20:1 ratio (20 parts
water to 1 part muriatic acid). Rub the Edge Form Liner with a stiff
nylon brush and the muriatic acid water. Rinse Form Liner thoroughly
with clean water.
- Store Edge Form Liners out of direct sunlight, laid out flat.
- If
Edge Form Liners ever get curved or twisted so they don't lay flat
naturally, the easiest solution is to lay them out flat on a concrete or
asphalt surface on a really hot day and let the sun heat them up,
straighten them out, and then when they cool they should hold their
shape more naturally.
