Product Specifications:Product Detail:
- 17" Long
- 14 1/2" Wide
- 1/4" to 3/4" Sloped Height.
- *Occasional imperfections may be present on Rubber Molds, and can be removed or altered using a sharp utility knife, or a very abrasive sand paper or resin-bound grinding discs.
- Rubber Drain Board insert for use with concrete countertop fabrication.
- The Plane Drainboard has a flat smooth surface that slopes from one end to the other, to create slope for water to drain into a sink area.
- The Plane Drainboard's flat design creates a simple and clean design drainboard. If trivets are desired, the size and placement of the trivet can be customized each time the drainboard mold is used. Trivets can be epoxied onto the finished concrete, or into a channel created by using the Channel Form Strips (sold separately).
- Clean, nice edges. Fast and simple to use. Add a professional drainboard to your countertop form in minutes.
- Seamless integral drainboard, countertop, and/or sink.
- Drainboard slopes toward sink.
- If the drainboard needs to be shaped (to meet flush with a specific sink), simply cut the rubber mold with a sharp razor knife, or fine tooth jigsaw blade.
- Made of extremely durable polyurethane that can flex and stay strong.
- Can be used in pre-cast or poured in place concrete work.
- 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'.
- Place Drainboard Mold in your form and silicone in place.
- For most applications (Precast), run a silicone a bead across the bottom edge of the Drainboard Mold to create a water-tight seal.
- If using for poured in place concrete countertops, press the drainboard down into the concrete surface, lightly tapping until flush with the surface, and then place a board or 2x4's across the top of the concrete and Drainboard Mold to hold it in place while the concrete sets up.
- Use of a Rubber Safe form release is recommended, and will create a smoother finish on the concrete, less air pockets, and make cleaning the rubber mold easier when finished.
- Vibrate concrete well (either vibrating the concrete, or rapidly tapping the edges of the forms with a hammer or palm sander), to remove as many air pocket voids as possible.
- After the concrete is sufficiently set up (typically 2-3 days for precast), flip the concrete piece over and remove the Drainboard Mold. In many cases, the mold will stay siliconed to the form when separated from the concrete.
- Concrete may have small 'bumps' which can be sanded off with a 200 grit sandpaper. These bumps tend to disappear the more the Rubber Drainboard Mold is used, as it becomes seasoned.
- Fill any air pocket voids with a Concrete Slurry Mix.
- 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 rubber mold in a 20:1 ratio (20 parts water to 1 part muriatic acid). Rub the Drainboard Mold with a stiff nylon brush and the muriatic acid water. Rinse the mold thoroughly with clean water.
- Store rubber molds out of direct sunlight, laid out flat.
