River table

Use deep-pour casting epoxy suited to the channel depth and volume. A thin-build tabletop coating is not a substitute.

Blue resin river between two live-edge wood slabs.

  1. Step 1. Choose the resin and layout

    Choose a casting epoxy approved for the planned depth, total pour volume and room temperature. Arrange the wood and river, measure the channel and plan any required layers. Confirm compatible sealers, pigments and the intended final finish before mixing.

    Plan the wood and the river

    Choose casting resin for the river, not a thin-build tabletop coating.

  2. Step 2. Prepare the wood

    Use stable, dry wood within the specified moisture limits. Remove bark, loose fibers and contamination from bonding edges, then prepare and remove dust as specified. Do not trap damp or weak material beneath a clear casting.

    Sanding block on the surface

    Clean before sanding, then remove dust. Confirm compatibility with existing finishes.

  3. Step 3. Build and seal the mold

    Use a level, supported, leak-tight form with a compatible release surface. Secure the wood against floating without damaging it. Seal porous wood where the system requires it, respecting the sealer recoat window. Keep release agent away from bonding faces.

    Seal the form and secure the wood

    Keep release material on the mold, not on wood that needs to bond.

  4. Step 4. Measure and mix

    Follow the exact resin-to-hardener ratio by the stated mass or volume basis. Add only approved colorants in the specified sequence. Mix uniformly, including sides and bottom, without pouring unmixed container residue into the work. Prepare only the permitted batch size.

    Use the exact product ratio and measurement basis. No universal ratio is shown.

  5. Step 5. Cast within the product limits

    Pour at the allowed depth and volume for the measured conditions. Follow any layered-pour interval and preparation requirements. Use only approved bubble-release methods; do not torch or improvise solvents. Watch for leaks and abnormal heat, following the SDS emergency guidance if needed.

    Control each casting layer

    Pour depth, total volume and temperature must all meet the selected resin limits.

  6. Step 6. Demold and prepare the surface

    Wait for the specified demolding and machining cure, not just a hard-feeling surface. Remove the form without stressing the casting. Level and sand using suitable equipment and dust controls, following the selected finish preparation. Investigate soft areas before covering them.

    Clean before sanding, then remove dust. Confirm compatibility with existing finishes.

  7. Step 7. Finish and support the table

    Apply the compatible furniture finish and allow its required service cure. Use a mounting design that supports the wood/resin assembly and accommodates wood movement. Protect from excessive sun and heat; do not assume food-contact approval. Follow the finish care instructions.

    Handling, finishing and service cure are different milestones.
