Buying Guide: Key Considerations For Split Face Masonry Block Work
- Material and durability: Wood blocks (bass or beech) offer good balance of weight, grip, and wear resistance; plastic options are lighter but may wear faster in heavy use.
- Groove design and grip: A precise groove (around 0.2 cm) helps secure the mason line and reduce slippage for accurate straight lines.
- Block count and bundle size: Larger kits reduce reloading time on multi-line layouts; consider project size when choosing a set.
- Weight and handling: Lighter blocks are easier to maneuver on tall or intricate layouts; heavier woods provide stability on windy sites.
- Storage and organization: Waist or curved designs can improve line capacity and keep a tidy work area, which minimizes tangling.
- Moisture and climate: Wood blocks should be kept dry to prevent warping; consider storage solutions in humid job sites.
