Yes, floor stain typically appears darker when first applied, but it will lighten slightly as it dries and cures. This is especially true with transparent or semi-transparent stains, which often deepen the wood tone initially. Within 2 to 3 days, the stain usually settles into its final colour, depending on factors like wood type, humidity, and the amount of product applied. Always test the stain on a small, hidden area to preview the final shade before committing to the full floor.
