How to Mix Two-Component Products
Learn how to mix two-component products, discover common mistakes to avoid, and uncover expert tips for excellent results.
Catalyzed paint products typically require the intermixing of two or more components. Following specific instructions is crucial to having successful results.
Before starting your project, be sure to consult the safety and technical data sheets for the Benjamin Moore products you’re using to make sure all proper precautions are followed.
Mixing Two-Component Products
Before using a two-component paint, you need to know how to properly catalyze the product for application. In this video, we demonstrate the proper way to mix two-component products before use.Step-by-Step Guide
Materials Needed for Mixing Epoxy Paint
What Are Two-Component Products?
Understanding Part A and Part B Components
Catalyzed paint products consist of two or more separate components that need to be mixed together before use, typically a resin and a catalyst.
When the resin is mixed with its paired catalyst, it creates a chemical reaction that hardens and cures the formula.
Once mixed, a two-component product usually has a limited pot life (or window in which the product is usable), which varies from product to product. Please see your product’s technical data sheet for more details.
How to Mix Two-Part Epoxy: Step-by-Step Process
Step 1: Gather the Materials Needed to Mix the Two-Component Product
For this project, you will need your desired two-component product. This may be a High Performance product such as HP4000 Polyamide Epoxy or HP5000 Aliphatic Urethane.
Once you have all the materials needed to properly mix your catalyzed product, you can proceed.
Step 2: Stir Each Component Separately
Before you combine anything, be sure each component is thoroughly mixed on its own.
Open both components and use the drill fitted with the paddle mixer to thoroughly mix each component individually.
Step 3: Combine the Two Components
Once you have mixed each component individually, combine them. You may do this in the manufacturer-supplied container or in another container large enough to hold both components in their entirety.
Step 4: Mix the Components Together
Using the drill fitted with the paddle mixer, blend the two components together on low speed. Keep the blade moving while gently stirring. The blade must stay immersed in the material to avoid spattering or failing to completely mix the components.
Continue blending the two-part mixture for three to five minutes until thoroughly mixed and incorporated. Use a stir stick to scrape the edge of the container during the mixing process to ensure all material is completely mixed.
Step 5: Reduce or Thin Your Two-Component Product (If Needed)
If reduction is necessary, add the appropriate solvent to the two-component product based on the manufacturer’s recommendations. Then mix until fully incorporated. This may not be necessary for all products.
Be sure to read your products’ technical data sheets for more information.
If reduction is not necessary, skip this step and proceed to Step 6.
Step 6: Take Time for Induction (If Needed)
Some two-component products need additional time to activate before use. Induction time is the time required for the two components to chemically react to each other before application. This ensures your product performs as expected.
If induction time is required, follow the manufacturer’s instructions and mix for an additional minute once induction is complete.
If your product doesn’t require induction time, skip this step and proceed to Step 7.
Step 7: Apply the Product
Once the necessary steps are completed, the mixing is finished and the product is ready to be applied.
