Averaging 2. One area that is always an expensive challenge to manage is the hundreds of tables, chairs and other amenities that make guests comfortable. Many pieces are destroyed by a single storm and the cost of replacing this furniture on a regular basis is enormous. At over 1, lbs. The initial order from one resort for a Royal Poinciana tree root table; units. The tree root is positioned and prepared for making the mold. Parting shims are used to divide the root model in half and also affixed around the bottom perimeter.

A drill mixer is used to thoroughly mix the two parts. The mold is made in 2 halves, each consisting of four layers of rubber. A support shell is applied to each half, allowed to cure and then removed.

The rubber mold is then removed from the original and it is ready for GFRC casting. GFRC is sprayed into the mold halves. The mold halves are brought together and secured. Mesh fiber and additional GFRC is hand applied to make seams disappear.

The casting is now ready for post-finishing and the mold is put back into production. A multi-step staining process makes the GFRC look exactly like the wood original. Leveling posts are positioned and secured to support the glass top.

Once the glass top is placed, it is checked for levelness before delivery. The finished table will be enjoyed for years by resort guests.

Step 1: Preparing Model The tree root is positioned and prepared for making the mold. Important Announcement We are open.Many different factors impact the ideal composition for concrete, and GFRC is no different.

There are a few different methods you can use for casting. A concrete mixture is sprayed into the forms using a special device that chops and sprays a separate stream of long fibers.

The concrete and fibers mix when they hit the form surface. Glass fibers are mixed directly into the fluid concrete. The mixture is then poured or sprayed into molds. The hybrid method for casting GFRC uses an inexpensive hopper gun the same kind used with drywall to spray a thin face coat into the forms. Once the face coat dries the fiber loaded backer mix is applied either by pouring or hand packing, just like ordinary concrete.

The high polymer content of GFRC often means that long term moist curing is unnecessary. Cover a freshly cast piece with plastic overnight, but as soon as it has gained enough strength it can be uncovered and processed.

Many GFRC pieces are stripped 16 to 24 hours after casting. Your skill level, the composition of your mix and the method used will determine how much processing is needed once your GFRC countertop is removed from its molds. Grouting may be needed to fill in bug holes or surface imperfections. Achieving a perfect piece right out of the mold is very difficult and requires great skill.

I hope you enjoyed this three-part series on GFRC. You may also view my FREE, 2. Finer sand tends to inhibit flowability while coarser material tends to run off of vertical sections and bounce back when being sprayed. Cement — Typical proportions use equal parts by weight of sand and cement.

Water — Common water to cement ratios range from. When determining how much water to use make sure to take the water content from your acrylic polymer into account. This can make calculating water to cement ratios difficult unless the solids content of the polymer is known. Higher fiber content increases strength but decreases workability. Spray-Up A concrete mixture is sprayed into the forms using a special device that chops and sprays a separate stream of long fibers.

Pros: Allows for very high fiber loads using long fibers resulting in greatest possible strength. Premix Glass fibers are mixed directly into the fluid concrete. Pros: Less expensive than spray-up, although a special spray gun and pump is required.A: The Concrete slurries are abrasive and corrosive materials that require compatible fluid passages made from Stainless Steel and certain plastics, FRP does not use Home Depot plumbing fittings that are made of steel.

A: FRP uses a our own designed peristaltic hose pump for it's ability to pump abrasive and corrosive materials. The slurry passages are engineered in such a way as to provide total residual-free cleanouts. Piston or diaphragm pumps leave material in the corners that cannot be cleaned out. This excessive friction can also cause premature curing of the slurry in the spray hose that can get expensive.

The RimSpray pump is easy to disassemble to replace a hardened hose by dropping down the lower housing and the rotor while leaving the entire drivetrain intact. A: Peristaltic pumps work using the process of peristalsis to pump products through a hose the same way that blood and oxygen are pumped around the body.

The hose sits around a rotor which, when turning, compresses a segment of the hose almost flat. This compression is released as the rotor moves around the hose with the hose reinforcements causing it to spring back to its round shape, thus creating a partial vacuum refilling the hose. This compression creates a seal and, as the rotor turns, any product on the discharge side of the rotor is propelled forward and displaced from the pump.

Combining this suction and discharge action results in a self-priming positive displacement pump. A: Most of the other equipment on the market that is being presented as cement processing equipment is lacking in technology. They typically work for the first few batches, then it becomes a high maintenance and troublesome piece of equipment. All components must be laid out for easy inspection and access. The entire system can be flushed with less than 5 gallons of water and in less than 10 minutes.

Competitor's are typically machined from a soft aluminum material. The pneumatic components are protected from the elements by a fiberglass control box enclosure. All fittings, clamps, fluid passageways are engineered and manufactured from Stainless Steel and certain plastics for corrosion resistance. Others use a chain drive to power their pumps.

The chain is prone to rust and slurry build-up, causing it to pop off. The chain is usually located in a position that makes it almost impossible to lubricate and is a maintenance nightmare when the chain pops off. All fasteners including the nuts and bolts are Stainless Steel to resist corrosion.VF is UV stable.

Important: This product has limited shelf life. Use as soon as possible after opening. Gently stir with a paddle for 30 seconds. Pre-mixing one time per 24 hour usage cycle is recommended.

Important: Components should be mixed in proper sequence. Standard concrete mixers may be used, but it is recommended to use a high shear mixer specially designed for GFRC to ensure a thoroughly mixed, lump free slurry is produced.

Step 8: Add the remaining plasticizer to achieve desired workability. Step 9: Reduce mixer speed to slow rpm and gradually add fiber Premix only until dispersed typically not more than one minute.

Important: Mixing too long or at too high a speed after fiber has been added can filamentize or damage the fiber, resulting in placement issues and reduced strengths. Casting - Pour mixture in a single spot at the lowest point of mold, and let mixture seek its level. Vibrating: After casting, consolidate the slurry and remove entrapped air using a vibrating table or hand vibrator.

Regardless of spray pump used, a face coat without fiber is typically applied first. After the face coat has properly stiffened, a fiber backup mix is applied in multiple passes, with proper compaction following each pass.

To prevent adhesion between the rubber and model surface, models made of porous materials gypsum plasters, concrete, wood, stone, etc. The sealing agent should be applied and allowed to completely dry prior to applying a release agent.

A liberal coat of release agent should be applied onto all surfaces that will contact the rubber. Follow with a light mist coating and let the release agent dry for 30 minutes. Because no two applications are quite the same, a small test application to determine suitability for your project is recommended if performance of this material is in question.

Liquid urethanes are moisture sensitive and will absorb atmospheric moisture. Mixing tools and containers should be clean and made of metal or plastic.

After dispensing equal amounts of Parts A and B into mixing container, mix thoroughly for at least 3 minutes making sure that you scrape the sides and bottom of the mixing container several times. If Mixing Large Quantities 16 lbs. Then, pour entire quantity into a new, clean mixing container and do it all over again. Although this product is formulated to minimize air bubbles in your the cured rubber, vacuum degassing prior to pouring rubber will further reduce entrapped air.
