Are there safer polyurethanes that can be used to finish wood floors?
There are many types of polyurethanes that can be used to coat wood floors. Common alternatives to MCUs include water-based polyurethanes and oil-based polyurethanes. These products also use chemical solvents that evaporate into the air. Water-based polyurethanes usually produce fewer odors and may contain less toxic ingredients but should be used with care. Oil-based products usually contain strong smelling solvents that may cause health concerns similar to MCUs. As with any chemical product, the manufacturer’s instructions must be followed. Improving ventilation can help to reduce the levels of airborne chemicals regardless of the product used.
