Glass Coat - 2 x 500ml
|Stock Level||Supplier SKU||Manufacturer SKU||Brand|
Glass Coat is a two-component epoxy resin system produced to give a strong, flexible and long lasting high-gloss coating to surfaces like artist's canvas, crafts, fabrics, jewellery, marble, plaster, wood, paper and photos. It is odourless and heat resistant when set, which makes it great for a multitude of different art and craft work. It can also be used in trays, tables, placemats, floors, decoupage crafts, coasters, clock-faces and bench-tops, and as an embedding medium. A single application of glass coat is equivalent to 50 coats of varnish, meaning you get a high-gloss finish in less time.

Glass Coat Instructions
Clean surface to be coated and seal if necessary. (See SEAL FIRST section below). Mask areas of the project you need to protect from the gloss (see USE OF MASKING TAPE below). Elevate project and lay plastic underneath to catch drips or overflows. You'll need a disposable mixing container, a broad mixing stirrer and a small disposable brush to mop up around the edges as Glass Coat dries. Foam applicators are not suitable for use. It is best to work in manageable batches when mixing, We recommend mixing quantities no greater than 125ml each of Part A and B in any single mix. If project requires larger quantities of gloss, then mix two or more batches at the same time in preparation.
Coverage will depend on the surface being treated but as a rule of thumb mix 250ml of product (125ml of each part) for each 60cm x 60cm area to be coated.
Measure precisely one part resin (red cap) and one part hardener (black cap) in a disposable mixing vessel. Inaccurate measuring will spoil the project. Check levels in each bottle after pouring to ensure equal quantities are used. You don't need to use a measuring vessel. Simply compare levels in the transparent bottles for accuracy. Tip: Remember that the resin (red cap) is thicker than the hardener (black cap), so allow a few second for contents to settle down the sides of the bottles before comparing levels.
Mix thoroughly with a BROAD FLAT STIRRER for several minutes, scraping down the sides and stirring with a slow mechanical motion. Tip: Don't be deceived by the fact that both parts are clear. They need to be just as thoroughly blended together as if you were mixing two distinctly different colours.
Flood the surface to be coated immediately. While Glass Coat can be applied with a brush, the best effect is achieved if it is poured over a level surface. Use a disposable brush or spreader to touch up sides or to move Glass Coat across the surface. It is important that the surface be as level as possible so that Glass Coat spreads evenly.
Burst The Bubbles
Bubbles will appear after the pour. Most of these will pop out almost immediately as Glass Coat is spread across surface. To fully remove air bubbles we recommend using a small propane torch, sweeping lightly over the treated surface. Use with care as the flame may scorch the surface if held too close. Don't use a hair dryer or devices that blow hot air over the surface. Blowing through a drinking straw, directing your breath at specific bubbles is suitable only for very small projects and is not the preferred method as moisture from your breath will leave dimples on the surface.
Setting And Curing
The glossed surface will be touch dry in a few hours, but must be left to set and cure for at least 24 hours in a dust free environment. Glass Coat will not flood over the surface as well on very cold days. An ambient temperature of at least 23 degrees Celsius is best and low humidity is preferred.
If the finish stays soft or sticky you have not measured correctly. If it is soft or sticky in parts of your project, you have not stirred it sufficiently. Refer to the USER'S GUIDE TO WORKING WITH Glass Coat on reverse of this page for procedures to follow.
Use Of Masking Tape
If you have used masking tape around edges of project remove BEFORE the surface fully dries, but AFTER Glass Coat ceases to flow down the sides of the project. We recommend the use of Craftsmart Silicone Tape or similar low-tack tape.
Clean up spills, drips and equipment while mix is liquid, using Glass Coat Epoxy Cleaner. Rough edges can be removed by sanding, once the surface is completely dry. Be sure to sand in a well-ventilated area and use an approved dust mask. You will however achieve a better finish if the edges are cleaned while the project is still wet. Refer section on USE OF MASKING TAPE.
Occasionally the surface of your project will contain oils and other contaminants preventing even adhesion of Glass Coat. This is the case with compressed timbers like MDF or chipboard. Sealing the surface before pouring is always the preferred option. Be careful not to touch the sealed surfaces with your fingers, as oil from your skin may contaminate the surface. Open grain timbers and softwoods are best sealed with Glass Coat Timber Sealer before applying Glass Coat. Wood stain, acrylic paint and some other pigments can generally be added to Glass Coat to create special effects, but always test first to ensure compatibility.
Seal project with single coat of Craftsmart Glaze PasteTM. Glue paper to the surface using Glaze Paste, allow to dry and re-apply sealant. When completely dry, apply Glass Coat as directed.
Glass Coat is ideal for most ceramics and terracotta. If in doubt about suitability, seal surface first, or test on sample before pouring.
Photographs, Certificates, Newsprint
Mount on craft wood with Craftsmart Glaze Paste. Allow drying. Apply photos or prints and follow the instructions for DECOUPAGE above. Because of chemicals on the surface of photographs, thorough sealing is always recommended.
Glass Coat will be heat resistant when cured. Allow at least 3 weeks curing time before putting hot plates onto the surface. Hot plates and casserole dishes, for example, will not affect the surface if proper curing has taken place, but test carefully before applying hot items to your surface.
Glass Coat is very hard when cured. However, the surface will scratch if used as a cutting surface. Never use abrasive cleaners on the surface.
Work in a well-ventilated room. Although Glass Coat is almost odourless, do not inhale fumes. Wear protective clothing, including disposable gloves and safety glasses when working in an enclosed area.
Refer to the bottles for First Aid information. Only adults or older children under strict adult supervision should use Glass Coat.
While there is no specific expiry date for use, it is recommended that Glass Coat be used within twelve months of purchase.
