Concrete Form Liner - 8" Slate Rock

  • 8" Slate Edge Form Liner, re-usable.
  • "Slate" edge detail, 8" tall by approx. 10 feet long.
  • Can be cut down to smaller sizes (for example, cut down to make 4 pieces each 2" x 10') using a razor blade and straight edge (table saw, jig saw, etc. can also work, but are more difficult).
  • When seaming together, the ends can be trimmed if needed with a sharp razor blade, and then a little Type II Silicone to blend the seam.
  • Designed for creating steps, fireplace hearths, capstones, or thick countertops.
  • 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.

Specifications Concrete Form Liner - 8" Slate Rock:

  • Measurements: 120"L (approx.) x 8"H.
    • *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 / resin-bound grinding discs.

Mold Setup Concrete Form Liner - 8" Slate Rock:

  • 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 polyurethane rubber safe Form Release (sold here) is recommended: Form release helps 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 normal precast concrete), 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 quickly with Diamond Sanding Pads (sold here). 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.

First time cement mantel

I watched video after video on the Internet to prepare. Despite this I had a few surprises which I thought would render my first effort a learning exercise. None though involved the lining which performed superbly. I had no trouble releasing the liner from the mantel and the slate pattern was perfect (a few pin holes that were easily fixed). I am a 70 yr old handy woman.

I bought the 5 pack to put on the face of my conrete steps leading to my stamped patio. Giving the irregularity of my steps i had to cut each one at a different height to adapt to my situation and it turned out awesome. I wiped them down with mineral spirits (let dry) then rubbed them with a powder release on the faces just before placing my concrete. I dont think they could have turned out any better. Also used the scrap pieces on the edge of a pad at the bottom of my wood steps. Can be reused several times and a great product!
