A high-strength paste, P1 is ideal for structural bonding, gap filling and repairs. Safe for surfaces in contact with potable water, it’s also resistant to hydrogen sulphide often found in pipes and plants used for sewage treatment.
Features & Benefits
- VOC-free: for structures involving drinking water.
- Excellent chemical resistance.
- Simple 1:1 mix ratio and easy-blend texture.
- Non-sag for vertical and overhead surfaces.
- High strength permanent bonds.
- Two-part solution.
Ideal Uses
Gap Filling & Bonding
Concrete Repair
Bonding Steel to Concrete
Fibre Cement Filling and Bonding
How to Use
Megapoxy P1 is a two-part, gap filling epoxy paste adhesive for many types of bonding and filling applications.
It is available in conveniently pre-packaged 1 litre, 4 litre and 20 litre kits with a simple 1:1 mix ratio.
It has a 1 hour work time and a 24 hour cure time at 25ºC.
Surface Preparation
Before begin mixing, you need to ensure that all contact surfaces like metal, concrete and stone are clean and clear of oil, dust and any other surface contaminants.
Concrete and stone surfaces should be prepared by grinding the surface and removing all the dust and debris.
This helps ensure effective bonding contact.
Compressed air can be used to remove dust from cracks and holes.
Clean metal surfaces with acetone to remove any oils or contaminants.
Safety and PPE
Megapoxy P1 is VOC-free. As with all epoxy resins, please wear appropriate PPE, including eyewear gloves and clothing.
Mixing
IMPORTANT. Only make a suitable quantity that can be used within the 60-minute work time!
Megapoxy P1 should be mixed on a non-porous, flat surface.
Using individual spatulas for Part A and Part B, measure out equal amounts from their containers. Place them next to each other on the mixing surface. Ensure you have the same height and roundness for both parts BEFORE combining.
To combine, using the spatulas, begin by folding the part A over the part B and then working together in a zig-zag motion.
Make sure to scrape the underneath the combined product and onto the flat mixing surface. This will help to collect and combine any un-mixed part A or B.
While mixing the epoxy, make sure to clean the spatulas by scraping off any un-combined Part A or part B and then mix thoroughly.
When the epoxy appears completely streak-free and uniform in colour, it’s ready for use.
Application
Megapoxy P1 is recommended for bonding precast concrete; metal-to-metal or concrete grouting bolts; compressed cement sheeting; bricks; ceramics; and natural stone.
Because it’s a thick paste, Megapoxy P1 can be applied easily with a trowel for a perfect bond. Megapoxy P1 is ideal for filling and repair of concrete pipes and tanks; filling core holes; patching concrete floors; stairs; posts; and flush filling counter-sunk screws in fibre cement.
Applying Megapoxy P1 to cracks and holes is easy and fast, and because it doesn’t sag, Megapoxy P1 is ideal for overhead or vertical surfaces. It’s rapid-setting and will cure even in cold or damp conditions, stronger than concrete with good chemical resistance and high compressive strength.
Clean-up
Uncured Megapoxy P1 can be cleaned with Megapoxy Thinners.
Please Dispose of contents and container in accordance with local, regional, national and international regulations.
Finishing
A smooth finish can be achieved by wetting a clean spatula with water and gliding it over the surface. Be sure to re-wet the blade frequently to prevent the epoxy gripping.
Once cured, Megapoxy P1 can be machined, sanded and polished to a fine finish.

What is the mix ratio for Megapoxy P1?
Designed for simplicity, Megapoxy P1 combines a 1:1 ratio by volume and an easy-blend texture. Ideal for civil engineering, this adhesive paste provides high-strength bonds with on-the-job ease. See our video for step-by-step instructions.
What is the working time for Megapoxy P1?
Megapoxy P1 provides a 60-minute working time at 25°C, offering the perfect balance of flexibility for detailed work and efficiency to keep your project on track. Read about how it was used on a major public transport project to fill gaps between segments once bridge construction was complete.
How can I remove uncured Megapoxy P1?
For fast and efficient cleanup of your tools and site, simply wipe away uncured Megapoxy P1 with Megapoxy thinners or acetone.
What is the best way to mix Megapoxy P1?
Megapoxy P1 is easy to mix on a large board, using a spatula or putty knife to achieve a smooth and reliable blend. Because it’s a thick paste, Megapoxy P1 is also simple to apply with a trowel for a perfect bond. Properly mixed and applied, Megapoxy P1 is a stone-like solid that will retain high-strength permanent bonds. See our video for step-by-step instructions.
What is the shelf life of Megapoxy P1?
Megapoxy P1 stays in excellent condition for two years when unopened, making it a dependable choice for future projects without worrying about waste.
Can I use Megapoxy P1 to seal my water tank?
Yes, Megapoxy P1 is ideal for sealing floor and wall joints in drinking water tanks, thanks to its potable water certification and ability to cure even in cold or damp conditions. Also, Megapoxy P1 is resistant to hydrogen sulphide that may be present in pipes and plants used for treatment of sewage.
Can I add more Part B to speed up curing of Megapoxy P1?
We don’t recommend changing the ratio as it can compromise Megapoxy P1’s chemical formulation – affecting its proven strength and durability. It’s best to follow our guidelines for consistent results.
Can I add water to thin Megapoxy P1?
No, we don’t recommend thinning Megapoxy P1 with water, as this alters the formula and may reduce its ability to bond and seal properly. If you need advice, we’re always here to make it easier to achieve great things: simply give us a call.
Strength on tap: revitalised brewery flooring and drainage
Oak Haven Brewery at Gosford RSL is known for its award-winning beers and modern design. The venue needed a solution for a section of flooring around a trough drain that had started lifting due to heat, water and other materials. Epoxy adhesion issues were also found inside the drain and around its piping. A tailored approach using Megapoxy products reinforced the floor, improving long-term durability, and ensured a well-sealed drainage system built for brewery conditions.
Sky-high quality and service: solutions for major public transport project
Megapoxy adhesive and grouting solutions were used in the construction of a four-kilometre elevated Skytrain – including a 270-metre cable-stayed bridge. This was part of Sydney Metro, a major public transport project designed to transform Sydney – with more trains and faster services across the network.
