Epoxy Primer Catalyst
This is the "part B" to our Epoxy Primer.
**MUST BE MIXED 50/50 WITH EPOXY PRIMER RESIN! ALLOW INDUCTION TIME OF AT LEAST 15 MINUTES AFTER MIXING*
Porcelain, cast iron, steel, or ceramic surfaces require a low-build primer system designed to hold tightly to the surface while retaining the flexibility that resists cracking. Our Low-Build Epoxy Primer Resin is just that product. This fast-dry tub epoxy primer is applied in 3 - 4 light tack coats without the worry of unevenness or runs. It takes just 5 - 10 minutes to dry. It even covers up minor pits or imperfections.

What is the role of the Epoxy Primer Catalyst in the refinishing system?
The Epoxy Primer Catalyst acts as the hardener in the 2-part epoxy system. It initiates and controls the chemical reaction that allows the epoxy primer resin to cure, creating a durable and properly bonded base for topcoats.
What is the correct mixing ratio for the Epoxy Primer Catalyst?
The Epoxy Primer Catalyst must be mixed at a 50/50 ratio with NAPCO Epoxy Primer Resin. Proper mixing is critical to ensure correct curing, adhesion, and overall coating performance.
Is induction time required after mixing?
Yes. After mixing the catalyst and resin, an induction time of at least 15 minutes is required. This allows the chemical reaction to begin before application, ensuring optimal bonding and performance.
What surfaces can this epoxy primer system be used on?
When properly mixed and applied, the epoxy primer system bonds to most bathtub, shower, tile, and surround surfaces that have been properly cleaned and etched. It is not recommended for use on fiberglass.
How does the epoxy primer improve refinishing results?
The epoxy primer creates a strong, durable base layer that enhances adhesion of the topcoat. It can also help fill minor voids caused by sanding or corrosion, improving the final finish and long-term performance.
What happens if the catalyst is not mixed correctly?
Incorrect mixing ratios or skipping induction time can lead to improper curing, poor adhesion, reduced durability, and potential coating failure. Following the specified mixing and application guidelines is essential for professional results.
