Proactive Troubleshooting
Scenario: Incorrect Mix Ratio or Poor Mixing
Potential Outcome: The adhesive will not cure properly, resulting in a soft, tacky, or weak bond. It may also lead to discolouration over time. This is the most common cause of epoxy failure.
Adheseal Best Practice: Always measure Part A and Part B accurately using the 2:1 by volume mix ratio. Mix thoroughly with a flat paddle, scraping the sides and bottom of the container to ensure the entire batch is homogenous before application.
Scenario: Application to Unprepared or Contaminated Surfaces
Potential Outcome: The adhesive will not achieve its maximum bond strength, potentially leading to delamination or bond failure under stress.
Adheseal Best Practice: All surfaces—stone, concrete, or metal—must be clean, dry, and free of all dust, grease, and loose material. Concrete must be mechanically abraded or acid-etched to remove laitance for a successful structural bond.
Applications in Practice: Trade Scenarios
For Stonemasons & Fabricators: Creating Flawless Mitre Joints
The Professional's Challenge
Creating a perfect, invisible mitre joint on a light-coloured marble benchtop requires an adhesive that won't stain, can be applied in a thin line, and provides immense strength and impact resistance.
The Adheseal Solution: Engineered Certainty in Practice
Megapoxy 63 is the ideal choice. Its translucent gel spreads easily to allow for tight, thin glue lines. The non-staining formula ensures there is no "picture framing" along the joint, and its high strength provides a durable edge that can be polished flawlessly once cured.
Best Practice Note
After lightly abrading the bonding surfaces, apply a consistent bead of mixed epoxy. Clamp the mitre joint firmly and allow a minimum of 24 hours to cure at 25°C before handling or polishing.
For Civil Engineers & Remedial Specialists: High-Strength Structural Bonding
The Professional's Challenge
A structural specification requires bonding precast concrete elements or anchoring threaded rods into a masonry substrate, demanding a bonding agent with verified strength properties superior to concrete.
The Adheseal Solution: Engineered Certainty in Practice
Megapoxy 63's verified performance data provides the confidence needed for specification. With a compressive strength of 120 MPa and a concrete bond strength greater than 3 MPa (typically resulting in concrete substrate failure), it delivers a permanent, structural bond you can depend on.
Best Practice Note
Ensure concrete is fully cured (min. 28 days) and mechanically prepared to remove all laitance. For critical applications, conduct an on-site adhesion test to verify the substrate preparation is adequate.

Applying Megapoxy 63: Professional Protocols
-
Step 1: Surface Preparation
Ensure all surfaces are structurally sound, clean, dry, and free from any contaminants like dust, oil, or grease. The minimum application temperature is 10°C.
Pro Tip: For concrete, mechanical abrasion (grinding) is the best method to remove laitance and create an ideal profile for a structural bond. -
Step 2: Mixing
Measure the components accurately and mix thoroughly. Inaccurate ratios or poor mixing is the primary cause of failure.
Mixing Ratio
Combine 2 parts of Part A with 1 part of Part B by volume.
Mixing Technique
Using a flat paddle, mix the two components thoroughly until a uniform, streak-free consistency is achieved. Scrape the sides and bottom of the container to ensure all material is blended.
-
Step 3: Application & Curing
Apply the mixed adhesive to the prepared surface within the 30-minute work time (at 25°C).
Application
Spread the gel adhesive with a notched trowel or spatula, ensuring full coverage of the bonding area. Bring the substrates together and clamp firmly.
Curing: Allow a minimum of 24 hours to cure at 25°C before subjecting the bond to stress or further processing like polishing. Full properties develop over 7 days.
Limitations & Safety
Product Limitations
Minimum application temperature is 10°C. Curing will be significantly delayed at lower temperatures.
Incorrect mixing ratio or insufficient mixing will result in a weak or failed bond.
Shelf life is 2 years minimum for unopened kits. Store in a cool, dry place out of direct sunlight.
Safety & Handling Requirements
Hazard Information
DANGER (Part B) / WARNING (Part A). Part B is corrosive and causes severe skin burns and eye damage. Part A causes skin and serious eye irritation. Both parts can cause an allergic skin reaction. Handle with extreme care.
Personal Protective Equipment (PPE)
Wear chemical-resistant gloves (nitrile rubber recommended), safety glasses with side shields or chemical goggles, and protective clothing. Ensure eyewash stations are accessible.

Skin:
Immediately remove contaminated clothing. Flush skin and hair with running water for 15 minutes. Seek medical attention if irritation or a rash occurs.
Inhaled:
Remove from exposure to fresh air. Seek medical advice if effects persist.
Swallowed:
Rinse mouth. DO NOT induce vomiting. Give a glass of water to drink and seek immediate medical advice. Call a POISON CENTRE (13 11 26).
Adhesion & Preparation Guide
Natural Stone & Porcelain
Surface Preparation
Surfaces must be completely clean, dry, and free of dust or processing residue. Lightly abrading the bonding areas can enhance adhesion on very smooth or polished surfaces.
Primer Requirements
No primer typically required
Megapoxy 63 is designed to bond directly to properly prepared stone surfaces without the need for a primer.
Concrete & Masonry
Surface Preparation
Concrete must be fully cured (minimum 28 days) and free from grease, oil, and laitance. Clean with an industrial degreaser, then mechanically abrade via grinding or shot blasting to achieve a clean, sound profile. Vacuum all dust.
Primer Requirements
No primer typically required
No primer is required, as Megapoxy 63 is a penetrating epoxy that bonds directly to a properly prepared concrete surface.
Coated Surfaces
Surface Preparation
For maximum performance, it is strongly recommended to remove all coatings (paint, sealers, etc.) via mechanical means to expose the bare substrate before applying Megapoxy 63.
Primer Requirements
Adhesion Test Recommended
Bonding to coated surfaces will result in inferior bond strengths, as the bond is only as strong as the coating's adhesion to the substrate. An adhesion test is essential if removal is not possible.
