€19.85–€133.67 (ex vat)
GlassCast® 3 epoxy resin is a remarkable clear epoxy resin developed specifically to provide a beautiful, hard wearing, clear gloss surface for tabletops, bartops, decorative floor effects, furniture and creative projects.
Glass Cast 3 epoxy resin can be poured at thicknesses from just 1mm up to 5mm or more but is recommended for coatings between 1mm and 3mm making it perfect for creating a glossy resin coating over furniture as well as creative ideas like bottle tops, crushed glass, pebbles and of course the incredibly popular pennies.
- Tabletops* (including embedments like bottletops, corks, pebbles, glitter, gravel)
- Bartops* (including crushed glass, beer mats etc.)
- Furniture (including reclaimed wood, driftwood, decoupage etc.)
- Penny floors

GlassCast 3 Clear Epoxy Coating Resin
This amazing resin is self-leveling and cures to leave a stunningly smooth, glossy surface which requires no flatting, polishing or further finishing – a true ‘pour and leave’ process. If you do need to polish the resin, however, to remove scratches or add a soft radiuses edge to a cast surface, for example, Glass Cast 3 is very easy to polish using simple abrasive paper and polishing compounds to restore a full gloss.
Special additives in the resin help to expel trapped air after mixing meaning that in most circumstances there is no need to pop bubbles with a torch or heat-gun.
The advanced ‘UV’ resistant formulation of Glass Cast means that it has non-yellowing properties far superior to those conventional epoxies meaning that it will start beautiful and stay beautiful for years to come.
*All epoxy resin systems will be marked by hot objects. To improve the heat resistance of your Glass Cast surface, an elevated temperature post-cure should be undertaken. Even after which, you should avoid placing particularly hot plates or cups on your Glass Cast surface.
GlassCast 3 is ideal as a clear floor resin making it the perfect choice for a resin penny floor or to include other embedment’s. To date, GlassCast 3 has been successfully used for thousands of penny floor projects in the UK and around the world.
Other GlassCast Versions
GlassCast 3 is the original GlassCast product which has now been renamed to GlassCast 3 having been joined by two new versions; GlassCast 10 and GlassCast 50. The number in the name is the suggested thickness that each product should be used for; GlassCast 3 is recommended for coatings up to 3mm in thickness whereas the new products are recommended for castings up to 10mm and 50mm.
For resin penny floors, countertops or similar, GlassCast 3 is the right product. For smaller clear resin castings such as jewelry or resin art (up to 10mm) in thickness, choose GlassCast 10 For infills into knot holes or distressed wood or if you’re doing a waney-edge river table then GlassCast 50 is the right choice.
Compatibility Information – Dos and Don’ts
Although by no means an exhaustive list, the mould materials, pigments and additives listed below have all been tested and are known to work well with Glass Cast.
|Compatible Pigments||Compatible Fillers|
|· Addition/platinum cure RTV silicone rubber
· Epoxy gelcoat based moulds
· Polypropylene and polyethylene sheet
· Toughened Glass (e.g. flat sheet manufacture)
|· Epoxy Colour Pigment (for vivid opaque colours)
· Translucent Tinting Pigment (for less vivid opaque colours)
· PearlEx® powder pigments
· All dry filler powders *
· All metal powders (for realistic cold castings)
· Photoluminescent (glow in the dark) powders
Glass Cast should not be cast into Condensation/tin cure RTV silicone rubber moulds.
* Use dry filler powders with caution as in most cases they will reduce the clarity of the Glass Cast, with the more filler used resulting in a greater negative impact on clarity
Key Processing Information
Ease of Use
Suitable for professional and hobby use (follow SDS advice).
Glass Cast is almost odourless.
Wear gloves and goggles and work in a well-ventilated area. Always read the SDS before use.
Can be used from 15 to 30°C although pot-life and cure time will be affected significantly. For best results casting at an ambient of 20-25°C is required.
Not necessary. Simply mix and pour.
Mix ‘Resin and ‘Hardener’ 2:1 by weight. Use digital scales.
Mix thoroughly by hand for at around 3 minutes.
30 minutes. Be sure to pour your casting(s) before this time.
Resin will heat-up whilst it cures. Very large batches of mixed resin in a pot will quickly overheat (exotherm) and can smoke/ignite. Never leave mixed resin unattended.
Maximum thickness per layer is 15mm. Thicker projects will require multiple pours to a maximum recommended thickness of 25mm.
Initial cure time is 24 hours to touch dry. Full hardness achieved over several days, ambient temperature dependent.
Pigments and Fillers
A wide range of pigments and fillers (including metal powders) can be added to change the appearance of castings.
How much resin will I need?
For solid surfaces, it’s easy to calculate the amount of resin you’ll need to cover a given area. For uneven surfaces or those including embedments like pennies, crushed glass or bottle tops; some compensation will be required.
1kg = 1mm over 1sqm
You will require 1 kilo of resin per millimetre of thickness required over a 1 sqm area. Therefore, to calculate how much resin to mix, simply multiply the thickness you require (in millimetres) by the area of your surface (in square metres). Don’t forget that porous (absorbent) materials like wood should be sealed before the main pour. Typically for a grouted penny floor, we would recommend 2mm thickness over the pennies which equate to 2kg per square meter. Other projects the depth may vary.
Use the table below as a quick guide to how much resin you would need to cover different areas at a range of thicknesses:
Surface Area to Cover
|25cm x 25cm (0.0625sqm)||50cm x 50cm (0.25sqm)||50cm x 100cm (0.5sqm)||100cm x 100cm (1sqm)||
200cm x 100cm (2sqm)
