Buying Guide: Key Considerations For Slate Flooring
What to ask when choosing slate flooring or slate tiles:
- Surface type: Do you want solid slate tiles for a traditional look or interlocking deck tiles for quick outdoor installations?
- Finish and color: Are you seeking bold black tones, neutral greys, or variegated natural textures?
- Durability and use: Will the area be high-traffic, wet, or exposed to sun and freeze-thaw cycles?
- Slip resistance: Is a textured cleft finish preferred for safety in outdoor spaces or around pools?
- Maintenance: What cleaning routine and sealant schedule does the space require?
Practical comparisons to help decide:
- Tile vs. interlocking deck tiles: Choose tiles for a seamless indoor floor or a stable outdoor deck that can be removed without tools.
- Color choices: Darker slate shades hide scratches and dirt better in high-traffic areas; lighter tones highlight grout lines and texture.
- Sealing needs: Some slate finishes are more porous; sealing can improve water repellency and stain resistance.
