Description
MEKP 925 CATALYST
MEKP 925 Catalyst (Methyl Ethyl Ketone Peroxide) is the essential activator for polyester and vinyl ester resins used in pool repairs and fiberglass applications.
When mixed with resin, it triggers a chemical reaction that generates heat to cure and harden the material, creating a durable, waterproof seal.
Available in multiple sizes to accommodate both small repairs and larger professional projects.
Use approximately 1/2 oz per quart of resin for optimal results.
We recommend using our MEKP Catalyst Dispenser (sold separately) for accurate measuring and safe handling.

Application Guide
- Safety First: Always wear protective gloves, eye protection, and work in a well-ventilated area.
- Preparation: Measure the required amount of resin for your project.
- Precise Measurement: Use our MEKP Catalyst Dispenser to accurately measure approximately 1/2 oz of catalyst per quart of resin, but check the manufacturer’s instructions for accurate measurements.
- Mixing: Add the catalyst to the resin (not the other way around) and mix thoroughly for 1-2 minutes.
- Working Time: Once mixed, you typically have 15-20 minutes of working time before the resin begins to gel.
- Application: Apply the catalyzed resin to your prepared repair area following specific project instructions.
- Curing: Allow 24-48 hours for complete curing, However, curing time can be influenced by factors such as temperature, humidity, and the specific resin being used.
Safety Information
Store in a cool, dry place away from direct sunlight. Keep away from heat sources and incompatible materials. Never mix directly with accelerators or promoters. Avoid contact with eyes, skin, and clothing. Keep the container tightly closed when not in use.
Frequently Asked Questions
1. How much catalyst should I use?
The standard ratio is 1/2 oz (approximately 15ml) per quart of resin. In cooler temperatures (below 70°F), you may increase to 3/4 oz. In warmer temperatures (above 85°F), reduce to 1/3 oz.
2. What happens if I use too much catalyst?
Too much catalyst can cause the resin to cure too quickly, potentially cracking or not bonding properly. It may also generate excessive heat.
3. Can I use this catalyst with any resin?
MEKP 925 Catalyst is designed for use with polyester and vinyl ester resins. It is not compatible with epoxy resins.
4. What’s the shelf life of MEKP catalyst?
When stored properly in original containers away from heat and sunlight, MEKP has a shelf life of approximately 12 months.
5. Is this product pool-safe?
Yes, once fully cured, repairs made with our resin and MEKP catalyst system are completely safe for swimming pool environments and resistant to pool chemicals.
