Megapoxy PM is a high-performance two-part epoxy adhesive paste designed for critical structural bonding and surface repairs where aesthetic preservation is mandatory. This thixotropic formula eliminates the risk of adhesive bleed-through or yellowing on high-value marble and natural stone while providing 80MPa compressive strength that exceeds standard concrete.
Engineered for efficiency in vertical and overhead applications, its true non-sag consistency allows for high-build repairs to spalled beams and columns without slumping. The 1:1 mix ratio and 45-minute working time ensure precise positioning for high-end fit-outs and structural rehabilitations. To ensure a permanent bond, substrates must be mechanically abraded to remove surface laitance before application.
Frequently Asked Questions
Will Megapoxy PM stain my white marble or light-coloured stone?
No. Megapoxy PM is specifically formulated to be non-staining. It will not stain or discolour white or light-coloured marble, granite, or ceramics, making it the ideal, risk-free choice for high-value stone installations. This predictable performance protects your work and reputation.
What is the mix ratio and work time for Megapoxy PM?
The mix ratio is a simple and reliable 1 Part A to 1 Part B by volume. Once mixed, you have a practical work time (pot life) of 45 minutes at 25°C, giving you ample time to apply, position, and tool the product without rushing.
Can I use Megapoxy PM for vertical or overhead repairs?
Absolutely. Megapoxy PM is a true non-sag, thixotropic paste. It has a creamy texture that is easy to trowel but will hold its position firmly, making it the perfect solution for vertical surfaces and overhead repairs where slumping or dripping is not an option.
What's the best way to prepare concrete before bonding with Megapoxy PM?
For a first-time-right structural bond, the concrete must be clean, dry, and free of all laitance. The best method is mechanical abrasion such as grit blasting, scabbling, or grinding. This ensures the epoxy is bonding to the sound, structural concrete, not a weak surface layer.

Applying Megapoxy PM: Enhanced Protocols & Best Practices
-
Step 1: Surface Preparation
Ensure all substrates are prepared according to the Adhesion Profile. Surfaces must be sound, clean, dry, and free of all contaminants to ensure a permanent, structural bond.
Pro Tip: Do not cut corners on preparation. 99% of bond failures are due to a poorly prepared substrate. Mechanical abrasion is always the best choice for concrete and metal. -
Step 2: Measuring & Mixing
This is a critical step for achieving the product's specified strength and non-staining properties. Inaccurate mixing will lead to cure failure.
Measuring
Measure exactly 1 Part A to 1 Part B by volume. Use calibrated mixing containers to ensure accuracy.
Mixing
On a clean board or in a mixing bucket, combine the two parts. Mix thoroughly with a spatula or mechanical mixer (for larger volumes) until the paste is a 100% uniform colour with no streaks visible.
Timing: The work time (pot life) is 45 minutes at 25°C. This time will be shorter in hotter weather and longer in cold weather. Only mix what you can comfortably use within this timeframe.Pro Tip: Always scrape the sides and bottom of the mixing container multiple times during mixing to ensure all material is blended and no unactivated resin or hardener remains. -
Step 3: Application & Curing
Apply the mixed paste to the prepared substrate using a trowel or spatula.
Application
For bonding, apply to one or both surfaces and press together. For repairs or gap filling, trowel the paste into the void, ensuring no air pockets are trapped. The non-sag formula will hold on vertical and overhead surfaces.
Cleaning
Clean all tools, implements, and spills *before* the epoxy cures. Use Megapoxy Thinners for effective cleanup.
Cure Time: Allow a minimum of 24 hours at 25°C for the initial cure. Full structural properties are achieved after several days.
Limitations & Safety
Product Limitations
Professional Use Only: This product is hazardous and intended for professional industrial/trade use. It is not for DIY use.
Sensitiser: Both Part A and Part B may cause an allergic skin reaction (sensitisation). Persons already sensitised may react to very low levels. Avoid all skin contact.
Mix Ratio: The 1:1 mix ratio by volume is critical. Do not alter this ratio, as it will result in a failed cure and loss of all physical properties.
Temperature: Do not apply at substrate or ambient temperatures below 10°C.
Preparation: Do not apply to unprepared, contaminated, or unsound substrates. Bond strength is entirely dependent on substrate quality.
Safety & Handling Requirements
Personal Protective Equipment (PPE)
Always wear safety glasses with side shields (or face shield) and protective gloves (nitrile rubber recommended). Wear protective clothing to prevent skin contact. Ensure an eyewash station is immediately accessible.
Ventilation Requirements
Natural ventilation should be adequate under normal use. Avoid breathing any dust generated during prep or application. Use in a well-ventilated area.
Fire & Handling Precautions
Non-combustible material. Flash Point is >200°C. Store in a cool, dry place out of direct sunlight and away from foodstuffs.
Emergency First Aid
Eyes:
CRITICAL: Part B causes serious, irreversible eye damage (Category 1). IF IN EYES: Rinse cautiously with water for at least 15 minutes. Remove contact lenses, if present and easy to do. Continue rinsing. Immediately call a POISON CENTER (Australia: 13 11 26) or doctor.
Skin:
Causes skin irritation and may cause allergic sensitisation. IF ON SKIN: Immediately remove all contaminated clothing. Wash skin thoroughly with plenty of soap and water. If skin irritation or rash occurs: Get medical advice.
Inhaled:
Remove victim from exposure to fresh air. Keep at rest. Seek medical advice if effects persist.
Swallowed:
Rinse mouth with water. Do NOT induce vomiting. Give a glass of water to drink. Seek medical advice immediately.
Refer to the Safety Data Sheet (SDS) for Part A and Part B before use.
Megapoxy PM Surface Preparation Guide
Concrete
Surface Preparation
Surfaces must be sound, clean, and free from grease and oil. Remove all surface laitance for a successful bond. Mechanical abrasion (grit blasting, grinding, or scabbling) is the best method. If this is not possible, acid etching can be used, but must be thoroughly washed and dried for 24 hours. For maximum adhesion, the concrete should be surface dry.
Primer Requirements
No primer specified
No primer is specified in the technical data. Adhesion is reliant on a clean, sound, and properly prepared substrate.
Metal Surfaces (Steel)
Surface Preparation
Metals must be grit blasted to AS CK 9.4-1964 Class 3 finish for maximum adhesion. If grit blasting is not possible, mechanically abrade the surface to a clean, bright metal finish. Once abraded, flood with an industrial grade degreaser to remove all contaminants. Note: Wire brushing is not entirely satisfactory and provides minimal adhesion only.
Primer Requirements
No primer specified
No primer is specified in the technical data. Bond performance is dependent on achieving a bright, clean, abraded metal finish.
Natural Stone & Ceramics
Surface Preparation
Surfaces must be thoroughly clean, dry, and free from dust, slurry, or processing residues. Ensure the back of the stone or tile is sound and has not been contaminated. Wipe with a clean, dry cloth before application.
Primer Requirements
No primer specified
Ensure surface is clean, dry, and sound.
