Megapoxy 63 is a translucent, two-part epoxy adhesive gel for natural stone mitres, porcelain edges and detailed masonry bonding. It forms a neat, thin glue line without the opaque finish of a typical repair paste, and can be tinted with compatible pigment paste.
Precision stone mitres and edge repairs
Use Megapoxy 63 to join mitred stone edges, bond natural stone or ceramic to prepared masonry, fill stone voids and rebuild chipped edges. The non-sag gel spreads with a notched trowel and stays where it is placed on vertical, angled and overhead work.
63, 69 or Megabond?
Choose 63 when a translucent thin glue line is the priority. Megapoxy 69 is a versatile non-sag gel for timber, metal, fibreglass and stone. Megapoxy Megabond is the creamy white, non-staining option for full-coverage bonding of stone and tile to masonry.
Before you apply
Grind or abrade the bonding faces and remove dust, oil and loose material. Mix two parts A to one part B by volume. Working time is approximately 30 minutes at 25°C, with a minimum 24-hour cure at that temperature. Do not apply below 10°C.
Can Megapoxy 63 be used for stone mitres?
Yes. The translucent, non-sag gel is designed for thin glue lines on natural stone mitres and close-fitting porcelain edges.
Can Megapoxy 63 be tinted?
Yes. Compatible Megapoxy pigment paste can be mixed in to make a visible joint closer to the stone colour.
What's the difference between Megapoxy 63 and Megabond?
63 is a translucent gel for thin mitres and edge details. Megabond is an off-white, non-staining, trowel-applied adhesive for bonding stone and tile to masonry.
Translucent epoxy gel makes tight stone mitres and edge repairs less visually prominent.
Non-sag application for prepared vertical, angled and overhead surfaces.
Suitable for stone and tile bonding, void filling and chipped edges.
Compatible with Megapoxy pigments; 2:1 mixing and 30-minute working time at 25°C.
Grind or abrade clean stone, porcelain or masonry and remove grinding dust. Mix two volumes of Part A to one volume of Part B until uniform. Spread with a notched trowel or apply as a gel to tight mitres and prepared voids. Work within 30 minutes at 25°C; minimum cure is 24 hours at that temperature.
Do not apply below 10°C, over paint, or onto dusty or contaminated surfaces.
Translucent epoxy is not invisible; test the final joint colour on visible stone before bonding.
For full-coverage white stone-to-masonry installation, Megabond is a more specific choice.
- Natural stone and engineered stone.
- Porcelain and ceramics.
- Concrete and masonry.
- Stone mitre joints and laminating details.
- Compatible bonding and gap-filling applications requiring a translucent adhesive.
