One more thing that you need to consider is the quality and type of wood. If the wood is oily such as cedar/redwood. Then you should consider going for an oil-based stain because it goes well with that type of wood. Also, the wood from pressure-treated pine goes well with water deck stains.
– Sealant provides an abundance of moisture protection. – Stain offers virtually no protection from moisture. Since many wooden decks are made of pine, or a similar “softwood,” they are not proficient in keeping out moisture, nor are they very good at withstanding UV rays.
The outdoor elements can take a toll on wood and make it look less than pristine. Pressure treatment helps protect wood from rot and insects with the help of high pressure and preservatives, helping to extend its life.

Pressure-treated wood contains preservatives to prevent rot and insect damage, but it remains vulnerable to the sun, wind, moisture and dirt. Learning how to stain pressure-treated wood can extend the life and improve its appearance.
Many people don't realize that early spring and summer are not the best time to apply stain to a deck. Wood absorbs humidity and accepts new treatments best when it's dry, so staining too early in the spring may lead to peeling or cracking.
As soon as the wood is porous enough to accept the stain, paint or sealant, it is ready for application. Typically, treated wood will dry and be ready for finishing 60 days after installation.
Ideally, wood that has been treated with a preserver should also be treated with a suitable top coat such as an wood oil, wood paint or wood varnish. These top-coat products seal in the preserver and provide protection against weathering and wear from direct contact.
