Do I Need Different Resin Types for Outdoor vs. Indoor?

What Sets Outdoor and Indoor Resins Apart?

Outdoor installations, such as driveways and garden pathways, are regularly exposed to sunlight, rain, and changing temperatures. For these areas, it’s best to use resins designed with enhanced UV resistance and permeability, which help protect the surface against yellowing, cracking, and water damage. Permeable systems like Flowstone provide water drainage and weather resilience for exterior use.

Indoor floors and decorative surfaces, however, benefit from resins emphasising hardness, clarity, and scratch resistance. Products tailored for interiors often prioritise a high-gloss, long-lasting finish and are less concerned with UV resistance, as sunlight exposure is reduced indoors.

Choosing the Right Resin for Your Space

• For Outdoor Use: Select resins marked as UV-resistant or formulated for external environments. Permeable options help prevent puddles and surface erosion in driveways and patios.
• For Indoor Use: Look for resins that offer clarity and durability, such as clear casting epoxy for floors, furniture, or countertops.

Always check the product guidance for surface compatibility and thickness recommendations, adjusting your choice according to specific requirements like aggregate colour or finish preference.

When This Matters

Opting for the correct resin is vital when longevity, appearance, and ease of maintenance are priorities. Using the wrong type can result in premature yellowing outside or insufficient durability indoors, making a tailored choice important for the intended setting.
