Installation Guide for Large-Scale Projects
Pre-Delivery Planning
- Crate Drop Route: Ensure access for forklifts or cranes to drop crates near the installation zone. Avoid tight corners or stairs.
- Site Organization: Designate a dry, level area for storage. Keep crates off wet ground to prevent staining.
- Quantity Verification: Double-check your order against the project plan. Batch-matching ensures color consistency across hundreds of units.
Crate Handling & Unloading
- Inspect Crates: Look for damage before signing. Crates are reinforced for rough transit.
- Unpacking Strategy: Open one crate at a time to avoid mix-ups. Use gloves to handle edges—marble can be sharp.
- Stacking: Store sills vertically on edge, not flat, to prevent stress cracks. Use padded separators between pieces.
Stone Quality Check
- Vein Consistency: Accept minor variations as natural character, but reject pieces with large fissures.
- Surface Finish: Check for honed or polished finish (specify in your order). No chips or pits on the top face.
- Dimensions: Measure length, width, and thickness against spec. Precision-cut, but always spot-check a sample.
Installation Prep
- Subfloor Leveling: Ensure window openings are square and level. Uneven bases cause breakage.
- Adhesive Choice: Use a high-bond, non-staining marble adhesive. Avoid acidic products that etch the surface.
- Sealing: Apply a penetrating sealer before install to protect against moisture. Re-seal after grouting.
On-Site Workflow
- Batch Installation: Install all sills in one zone before moving to the next. Minimizes dust and traffic.
- Cutting: Use a wet saw with a diamond blade for clean edges. Dry cutting creates heat cracks.
- Spacing: Leave 1/8-inch expansion gaps at ends. Fill with color-matched caulk, not grout, for flexibility.
Post-Install Care
- Clean Up: Wipe off excess adhesive immediately. Use a pH-neutral cleaner for final wipe-down.
- Protection: Cover sills with cardboard or plastic until project handover. Avoid heavy tools on top.
- Warranty Note: Comes with a 5-year structural warranty. Report any defects within 30 days.
