Buying Guide: Key Purchase Considerations
- Finish and appearance: Choose between high-gloss aesthetics for a showroom look and satin or non-slip finishes for safety and maintenance in high-traffic areas.
- Solids content: Higher solids typically deliver greater durability and abrasion resistance, but may require longer curing times or proper ventilation during application.
- UV and weather resistance: For interior/exterior use, ensure the coating offers weathering resistance to prevent yellowing or degradation from sunlight and exposure.
- Application surface: Confirm compatibility with bare concrete, existing epoxy floors, or over decorative coatings to ensure optimal adhesion and performance.
- Reactivity and safety: Some products are 2-component systems with specific mixing ratios; follow the manufacturer’s safety guidelines and product return policies.
- Safety features: Non-slip options are essential for garages, workshops, and commercial spaces to reduce slip hazards while maintaining aesthetics.
- Maintenance: Consider cleanability, stain resistance, and whether the finish can be resealed or touched up over time without removing existing coatings.
- Coverage considerations: Evaluate area size and kit yield (in gallons or square feet) to determine the number of kits needed for your space.
- Cure time and climate: Temperature and humidity affect cure rates; plan installation during favorable environmental conditions for best results.
