Yes, there are several products available that can seal unstained maple without turning it orange like polyurethane. Here are a few options:
Water-Based Polyurethane: While traditional oil-based polyurethane tends to give a slightly amber or orange tone to wood, water-based polyurethane is generally clearer and won't alter the color of the wood as much. Look for a water-based polyurethane specifically designed for hardwood floors or furniture.
Shellac: Shellac is a natural resin that can be used to seal maple wood without significantly altering its color. It dries clear and offers a protective finish. It is available in various shades, so make sure to choose a clear or blonde shellac for minimal color change.
Lacquer: Lacquer is another option for sealing unstained maple. It dries clear and provides a durable finish. Look for a clear lacquer that is specifically designed for wood furniture or cabinets.
Danish Oil: Danish oil is a blend of oils and varnish that penetrates the wood to enhance its natural beauty while providing a protective seal. It is available in different finishes, including clear or natural, which will preserve the natural color of the maple without adding an orange tint.
Before applying any sealer or finish, it's a good idea to test it on a small, inconspicuous area of the maple to ensure that you achieve the desired results. Additionally, always follow the manufacturer's instructions for proper application and drying times.
