When it comes to creating durable, high-quality HDU (High-Density Urethane) signs, the choice of primer can make all the difference. Among the options available, Matthews 6001SP Hardening Primer stands out as arguably the best in the industry.
Here are 7 tips to help you get the most out of this exceptional product, along with insights into why it's considered the top choice for HDU signage.
1. Proper Surface Preparation
Before applying Matthews 6001SP, ensure your HDU surface is clean, dry, and free from dust or debris. Lightly sand the surface to create a better bonding surface. This primer's excellent adhesion properties shine when applied to a well-prepared substrate.
2. Mix Thoroughly
Matthews 6001SP is a two-component primer. Always mix the components thoroughly according to the manufacturer's instructions. Proper mixing ensures optimal performance and durability of the primer coat.
3. Apply in Thin, Even Coats
For best results, apply Matthews 6001SP in thin, even coats. This primer flows and levels exceptionally well, providing a smooth surface for topcoats. Multiple thin coats are preferable to a single thick coat, as they allow for better curing and reduce the risk of solvent entrapment.
4. Respect the Pot Life
Once mixed, Matthews 6001SP has a limited pot life. Be sure to only mix what you can use within the specified time frame. This ensures the primer maintains its optimal properties throughout the application process.
5. Allow Proper Drying Time
While Matthews 6001SP dries relatively quickly, it's crucial to allow adequate drying time between coats and before applying topcoats. This patience pays off in the long run with a more durable, longer-lasting finish.
6. Sand Between Coats if Necessary
If you need an ultra-smooth finish, lightly sand between coats of Matthews 6001SP. This primer sands easily, allowing you to achieve a flawless surface for your HDU sign.
7. Use Appropriate Safety Equipment
As with any primer, always use appropriate personal protective equipment when working with Matthews 6001SP. This includes respiratory protection, gloves, and eye protection.
