Counter Top Clear Epoxy - Tarbender
Tarbender is a clear liquid epoxy that can be poured or brushed over a variety of surfaces to provide a strong, high gloss coating. It can be applied over wood, plaster, concrete, foam, fabrics, paper, etc. can be used to encapsulate 2-D or 3-D objects. Tarbender™ is certified “aquarium safe” and used by aquariums to create hyperrealistic coral and other aquarium displays. It is also used by zoos around the world as a coating for themed elements and displays.
Parts A and B mix together and flow easily. Tarbender™ epoxy cures at room temperature and offers high impact resistance. Features UV resistant Optically clear 2A:1B by volume mix ratio - no scale needed.
Product and Work Area Preparation – Tarbender™ containersshould be stored and used at room temperature (73° F/23° C). Wear longsleeve garments, disposable gloves and safety glasses. Mixing containersshould have straight sides and a flat bottom. Mixing sticks should be flatand stiff with defined edges for scraping the sides and bottom of yourmixing container. Have all materials and tools on site before you begin.Mixing containers should be made of plastic, metal or wax coated paper.Due to very high temperature potential (exotherm) of Tarbender™, donot use glass or foam containers.
Ventilation - Use only in a well ventilated area and avoid breathingfumes. Wearing a NIOSH approved respirator is recommended.
Mixing – Mix using a flat edge mixing stick for 2 minutes. Scrape thesides and bottom of the mixing container with the edge several times. Pourcontents into a new, clean mixing container and mix again for 2 minutes.If using a drill mixer, use a variable speed mixer set to low rpm and mix for2 minutes. Creating a vortex will introduce air. Follow with hand mixingfor 2 minutes. A large mass concentration of epoxy will reduce pot life andmay become too hot to handle. If concentrated mass of epoxy begins toget very hot, move outside to open air. To extend working time, reducemass by pouring mixture into a flat baking pan and pour onto bar topfrom there.
Pre-Mixing - Stir or shake Part A and Part B thoroughly before dispensing.
Measuring – Accurately measure 2A:1B by volume into a plastic, metal or wax-free mixing container.
Pouring Tarbender™ Over Flat Surfaces
Usage Overview – Most bar tops, tabletops and other flat surfaces require 2 – 3 layers of Tarbender™ with a 4-hour cure time in between layers. You can apply as many ¼” (6.4mm) layers as needed.
|Amount||Poured at 1/16”(1.6mm)||Poured at 1/8” (3.2mm)||Poured at 1/4” (6.4mm)|
|1 oz. / 28.3 grams||25.4 in² / 164 cm²||12.7 in² / 82 cm²||6.4 in² / 41 cm²|
|Trial Unit (2.83 lbs. /1.28 kg)||8 ft² / 0.74 m²||4 ft² / 0.37 m²||2 ft² / 0.19 m²|

Surface Preparation – Surface to be coated with liquid epoxy should be level in all directions. Surface must be free of dust, oilsor other contaminants. Tarbender™ should not be used on surfaces coated with oil-based stain, as it will delaminate. Water basedstains are compatible.
Sealing Porous Surfaces – unfinished wood surfaces, stone, marble, concrete,etc. should be sealed with a thin layer of Tarbender™. See “Pouring and SpreadingTarbender™” section below.
Do Not Vacuum – Subjecting mixture to vacuum will introduce air.
Pouring Tarbender™ - After mixing, pour a thin stream along the entire lengthof the surface. Do not exceed 1/16” (1.6 mm) for this layer. Your goal is to obtain aneven coating. Let Tarbender™ cure for 4 hours before applying another layer. Note; donot exceed ¼” (6.4 mm) thickness per pour. If greater thicknesses are desired, pour inlayers of ¼” (6.4 mm) with 4 hours minimum between layers.
For coating bar tops, a minimum thickness of 1/8” (3.2 mm) or two layers isrecommended.
Non-Porous Surfaces do not require a sealing coat. Mix and pour Tarbender™ asdirected to ¼” (6.4 mm) thickness. Look for bubbles and lightly pass propane torchover surface to dissipate. Let cure for 4 hours.
Dissipating Bubbles from Surface Using a Propane Torch - AfterTarbender™ is poured, pass a propane torch (available at any hardware or DIY store)back and forth lightly over surface to dissipate bubbles. Be careful when handling thetorch and do not get closer to the surface than 3” (7.62 cm). If pouring multiple layers,use a propane torch to dissipate bubbles after pouring each layer.
If Encapsulating 3-D Objects – Apply a 1/16” (1.6 mm) coating to bar top asdirected above. Dissipate bubbles with torch. Let cure for 4 hours. Place objectson top of cured layer. Mix a small amount of Tarbender™ and pour directly over andaround objects to break surface tension.
If Encapsulating Paper, Cardboard, etc. – Laminate paper beforeencapsulating. You can also seal surface with white glue (such as Elmer’s Glue)mixed 4 parts glue to 1 part water). Allow to dry for 16 hours before encapsulating inTarbender™.
Brushing Tarbender™ Onto Surfaces
Apply In Thin Layers - two thin layers of Tarbender™ are recommended for asmooth, uniform coating. Using chip brush, apply 1st thin layer to surface and letepoxy partially cure until “tacky hard”. Apply 2nd thin layer. Allow both layers tofully cure.
Adding Color – You can add UVO™ or IGNITE™ colorants or Cast Magic™ EffectsFillers. Pre-mix color or filler into Tarbender™ Part A thoroughly and then add Part B.
Adding New to Old - If too much time passes (72 hours or more) betweenapplying layers of Tarbender™, delaminating may occur if you try to add more. ForBest Results; lightly sand cured epoxy surface with 220 grit sand paper and wipe cleanwith denatured alcohol before mixing and applying new Tarbender™.
Clean Up – 90% Isopropyl Alcohol will remove uncured Tarbender™ from mostsurfaces. It can also be used to clean the surface of cured Tarbender™ epoxy. Alcoholis flammable. Follow all safety precautions for handling flammable liquids andprovide adequate ventilation.
Performance – Unpainted Tarbender™ will yellow after being exposed to outdoor UV light or excessive heat above 115°F/46°C forextended periods. Tarbender™ can be displayed outdoors after priming and painting with an aliphatic urethane clear coat.
