When to Choose Megapoxy PM Over Other Options:
- Choose Megapoxy PM over silicone or polyurethane adhesives when: Precise placement, no movement, and maximum structural integrity are required — especially for metal-to-concrete or anchor fixing.
- Choose Megapoxy PM over solvent-based fillers when: VOC sensitivity or flammability risks are a concern, or a clean indoor job requires odourless, user-safe materials.
- Megapoxy PM is particularly effective for: Precast concrete patching, bolt grouting, compressed sheet bonding, and structural repair of fibreglass, stairs, and tanks.
- Consider other Adheseal solutions when: Flexibility or movement accommodation is critical (e.g., expansion joints). Try Adheseal FlexJoint or MarinePro for submerged applications.
Trade-Specific Applications & Pro Tips for Megapoxy PM:
For Builders and Civil Repair Teams:
-
Application Focus: Bonding precast concrete panels
- Micro-Guide: Scabble or acid etch mating faces. Apply mixed epoxy generously. Clamp or weight for full cure.
- Compatibility Notes: Excellent adhesion to cured concrete, even with minor dampness present.
- Performance Benefits: Delivers compressive strength greater than the concrete itself, ensuring permanent structural integrity.
- Pro Tip: Allow 24 hours before backfilling or applying load where possible.
- Common Pitfall: Applying over dusty or laitance-covered surfaces — always prepare properly.
Frequently Asked Questions About Megapoxy PM
Q: Can I apply Megapoxy PM to damp concrete?
A: Yes. Megapoxy PM is formulated to cure under adverse conditions, including damp or cold substrates. Ensure surface is clean and free of laitance for optimal adhesion.
Q: Is Megapoxy PM suitable for vertical or overhead applications?
A: Absolutely. Its non-sag paste consistency makes it ideal for vertical and overhead bonding or patching — it stays where you put it without slumping.
Q: Does it bond well to metal surfaces?
A: Yes, with correct preparation. Grit blasting or mechanical abrasion followed by degreasing provides excellent bonding surfaces for steel, aluminium and other metals.
Q: Can I use Megapoxy PM indoors?
A: Yes. It’s VOC-free and low odour, making it safe and suitable for indoor applications including hospitals, commercial interiors, and residential environments.
Q: What is the best way to clean tools after use?
A: Use Megapoxy Thinners while the epoxy is still uncured. For cured material, mechanical removal may be necessary. Always wear gloves and eye protection.
Q: Is it paintable or sandable after cure?
A: Yes. Once fully cured, Megapoxy PM can be sanded smooth and painted with suitable coatings. Allow appropriate curing time before finishing.

Step-by-Step Application Guide for Megapoxy PM:
- Preparation is Paramount: Clean all surfaces thoroughly. Concrete should be free of grease and laitance. For metals, abrade to bare metal and degrease. Ensure surfaces are dry or minimally damp.
- Nozzle & Gun Setup: If using dispensers, ensure both components are mixed in a 1:1 volume ratio. For large batches, mix Part A and Part B thoroughly by hand or mechanical stirrer.
- Application Technique: Apply with spatula or trowel. Push epoxy firmly into joints or cracks. On vertical/overhead surfaces, apply thicker layers to hold shape.
- Tooling for a Professional Finish: Smooth with spatula within 45 minutes of mixing. Remove excess material with cloth dampened in Megapoxy Thinners.
- Clean-Up: Use Megapoxy Thinners before product sets. For cured product, mechanical removal is required.
- Curing Process: Allow 24 hours at 25°C before subjecting to load. Cure times vary with temperature. Protect from water exposure during cure.
Important Limitations & Safety When Using Megapoxy PM:
Product Limitations:
- Not suitable for continuous underwater immersion: Use Adheseal MarinePro for submerged bonding applications.
- May not bond well to highly oily or glossy plastics: Conduct compatibility test or use specialised primers for challenging materials.
- Cure time can be affected in temperatures below 10°C: Precondition material or warm environment if faster set is required.
Safety First – Protecting Yourself and Your Workspace:
- Personal Protective Equipment (PPE): Use chemical-resistant gloves (AS/NZS 2161), safety glasses (AS/NZS 1337.1), and long-sleeved clothing.
