Can I Use Liquid Resin on Old Cement Tiles Outdoors?

← Back to How to Protect Cement Tiles from the Sun with Liquid Resins?

Applying liquid resin to old cement tiles outdoors can be an effective way to safeguard them from weather and sunlight, restoring both their durability and appearance. However, several crucial steps help ensure lasting, protective results.

Surface Preparation: The Foundation for Success

For liquid resin to properly adhere, the cement tiles must be thoroughly cleaned and allowed to dry completely. Any loose debris, old sealers, algae, oils, or contaminants should be removed to create a sound surface. Using a dedicated product such as the Strong Technical Degreaser ensures a deep clean without harsh chemicals or damage to the tiles. Only after the tiles are dry and intact should you proceed with resin application.

Choosing the Right Resin for Outdoor Cement Tiles

Selecting a suitable resin for exterior conditions is essential. For cement tiles, consider a one-component methacrylic resin like Resinstone, designed specifically for absorbent surfaces such as concrete and cement. This resin offers waterproofing while remaining breathable to prevent trapped moisture, and it also provides resistance to UV rays and weathering. For tougher environments or where a strong, durable finish is required, a polyurethane (PU) coating like Prolux may be appropriate, offering high abrasion and UV resistance suitable for driveable or high-traffic areas.

Application Tips for a Lasting Finish

Always work in stable, dry weather for best adhesion.
Apply resin with consistent, even coverage to avoid streaks or pooling.
Follow the manufacturer’s drying and curing times strictly—avoid foot traffic until fully set.
For best long-term protection, maintain your resin-coated tiles by gently cleaning and reapplying resin as signs of wear appear.
