Water-based sealers are ideal for wood with a low absorption rate, like alder, birch, and maple.However, an oil-based wood sealer typically has better UV resistance and tends to have a more even finish. Oil-based sealers are better for pine, cedar, oak, ash, and other types of wood that have a high absorption rate because oil-based sealers are not as easy for the wood to absorb as water-based products.Outdoor wood sealers can be split into oil-based and water-based products, each with its own drawbacks and benefits. The main types include oil-based, water-based, solid/opaque, semitransparent, and clear. There are several types of wood sealers that are differentiated by the formula and transparency.

So to protect your outdoor furniture, fence, or deck from ongoing damage, it’s necessary to apply paint, stain, or sealant to the wood. Additionally, ultraviolet (UV) radiation can dry out wood, causing it to splinter and crack. Wood is susceptible to mold, mildew, and rot if it is left exposed to rain, sleek, snow, and other moisture.
