Finishing a magnesium oxide (MgO) board involves several steps to ensure durability and aesthetic appeal, and to maximize its fire-resistant and moisture-resistant properties. Here is a general guide on how to finish an MgO board:
Surface Preparation
Clean the Surface: Make sure the MgO board is free from dust, debris, or any contaminants. Wipe it down with a damp cloth or use a vacuum to remove dust. Ensure the board is dry before starting any finishing work.
Smooth Edges: Sand the edges of the board if needed to remove any roughness or imperfections, especially if the boards have been cut.
Joint Treatment
Use Joint Tape: Apply fiberglass mesh tape over the seams between boards. MgO boards are often used for wall sheathing or interior paneling, so treating the seams properly is crucial to creating a smooth finish.
Apply Joint Compound: Use a high-quality joint compound suitable for MgO boards. Apply it over the tape with a trowel, making sure to feather the edges for a seamless look. Allow it to dry completely.
Sand the Joints: After the compound dries, sand the area to smooth out the surface, preparing it for further finishing layers.
Priming
Choose the Right Primer: For interior applications, use a high-quality water-based primer suitable for MgO boards. For exterior applications, use a primer with moisture-resistant properties.
Apply Primer: Roll or spray the primer onto the surface, ensuring even coverage. Allow the primer to dry according to the manufacturer's instructions.
Painting or Texturing
Painting: MgO boards can be painted with most latex-based or acrylic paints. Apply two coats of paint for better durability and coverage. Make sure the first coat dries completely before applying the second coat.
Texturing: If you prefer a textured finish, apply a texture compound to the surface after priming. You can use a trowel or roller to achieve the desired texture, then paint over it once it's dry.
Tiling (Optional)
If you are using MgO board as a substrate for tiles (such as in bathrooms or kitchens), apply a waterproofing membrane over the MgO board first. After that, you can proceed with standard tile adhesive and grout application.
Sealing (Optional for Exterior Applications)
Weatherproofing: Apply a weather-resistant sealant or coating to protect the MgO board from moisture for exterior applications. This step is particularly important if the board is exposed to the elements.
Seal All Penetrations: Ensure that any screw holes or joints are properly sealed with a water-resistant sealant to maintain the board’s moisture-resistant properties.
Fastener Treatment
Countersink Fasteners: If using screws to fasten the MgO board, make sure the heads are countersunk slightly below the surface. Fill any visible screw holes with joint compound or a filler suitable for MgO boards, then sand them smooth before priming.
Best Practices
Moisture Control: MgO boards have moisture-resistant properties, but ensuring proper waterproofing is essential, especially in exterior or wet area applications.
Expansion Gaps: Leave small gaps between MgO boards to accommodate any expansion or contraction, especially in areas exposed to humidity or temperature changes.
Use Compatible Products: Make sure that any joint compound, primer, paint, or adhesives used are compatible with MgO boards to prevent issues with adhesion or durability.
By following these steps, you can achieve a smooth, durable finish on MgO boards, suitable for various applications, including walls, ceilings, and exterior cladding.
