Water-Based Primers
...
Use Water-Based Primers for: Preparing surfaces for painting, sealing, and adhesive application, with low VOC emissions and easy cleanup.
Water-based primers are designed to provide a smooth, uniform surface for subsequent coatings, enhancing adhesion and durability. These primers are formulated with low volatile organic compounds (VOCs), making them a more environmentally friendly choice. They are easy to apply, quick-drying, and offer excellent adhesion to various substrates, making them ideal for both interior and exterior applications.
Key Features
- Low VOC emissions
- Easy application and cleanup
- Quick-drying formulation
- Excellent adhesion to various substrates
- Reduces substrate porosity
- Improves topcoat adhesion and finish
- Suitable for interior and exterior applications
Trade Professional Information
- Required Tools: Application brushes, rollers, spray equipment, mixing buckets, sanding blocks, cleaning cloths, safety glasses, gloves.
- Trade-Specific Tips: Ensure substrates are clean, dry, and free from contaminants. Sand glossy surfaces for better adhesion. Apply primer evenly and avoid over-application. Allow sufficient drying time before applying topcoats. Clean tools with water immediately after use. Test a small area for compatibility before full application.

Common Issues and Solutions:
- Issue: Poor adhesion to glossy surfaces. Solution: Sand glossy surfaces thoroughly before applying primer.
- Issue: Uneven primer application. Solution: Apply primer in thin, even coats using a quality brush or roller.
- Issue: Slow drying time in humid conditions. Solution: Ensure proper ventilation and allow extra drying time.
- Issue: Primer peeling or blistering. Solution: Ensure proper substrate preparation and avoid applying primer to wet or contaminated surfaces.
