Buying Guide: Epoxy Putty for Ceramics
What to consider when selecting epoxy putty
- Setting time and cure duration: Choose based on project size and whether you need quick handling or full cure for painting and finishing.
- Strength and durability: Consider temperature exposure, moisture, and chemical resistance for the repair location.
- Water exposure: For ceramic repairs near plumbing or pools, select underwater-capable putty if allowed by the product data.
- Substrate compatibility: Ensure the putty adheres well to ceramics and any adjacent materials (metal, wood, tile, plastic).
- Ease of use: Look for 1:1 mix ratios or simple knead-and-apply workflows for faster repairs.
How to apply epoxy putty for best results
- Clean and dry the surface before applying. Remove grease, dust, and loose material.
