Preparing the correct surface is key to achieving a strong, lasting bond with Caldart epoxy primer. Let’s explore which types of surfaces are best suited for this primer and how to ensure the best results for your project.
Compatible Surfaces for Epoxy Primer
Caldart epoxy primer is designed for excellent adhesion to a variety of common building materials. It is especially suitable for concrete floors, screeded surfaces, timber, and ceramic tiles. This versatility makes it a go-to choice for both residential and commercial projects, whether you’re working in living spaces or work environments.
- Concrete: Ideal for garages, workshops, and industrial floors.
- Timber: Suitable for wooden flooring or surfaces that require sealing before coating.
- Screeds: Works well on sand-cement or similar screed finishes, providing a smooth base for further treatment.
- Ceramic Tiles: Prepares glazed or porous tiles for effective resin topcoats.
Best Practices for Application
Surface preparation is crucial. Begin by removing dust, oils, and any loose or flaky material. Surfaces should be dry and free from standing moisture. For tiles, a light abrasion may improve primer adhesion. When ready, apply the primer using a roller, brush, or spatula for even coverage—Resin & Paint Application Rollers work well for larger or detailed areas. Always check porosity, as this affects how much primer you’ll need, typically 100–300 g/m².
When Surface Choice Matters
Selecting the right substrate for Caldart epoxy primer is especially important if you’re aiming for high-traffic durability, or applying decorative resin layers or pebble floors. Certain surfaces, such as plastics or metals, are not recommended unless further pre-treatment is performed, so always match the primer to the intended material for reliable results.
