What are Pressure- Treated Woods?
Pressure-treated woods are woods treated with liquid chemicals by submerging them in these chemicals to prevent decay from insects and other elements like moisture and UV rays, thereby extending their life.
Does Pressure Treated Woods Need to be sealed?
Because many kinds of wood aren’t manufactured to withstand adverse actions from harsh elements such as wind gusts, UV rays, moisture, they are treated with chemicals. Yet, these pressure-treated woods still require additional treatments from sealants.
When moisture seeps into woods, they become absorbed and evaporate on sunny days. This causes them to expand and contract over time. Intense sun rays can also cause peeling and fading of exterior decks and furniture, changing their looks. Hence, Pressure-treated woods still need to be sealed against these elements as sealing helps prevent splitting or cracking of woods and provides an attractive appearance.
Is it better to Paint or Stain Pressure-Treated Woods?
Pains are less likely to adhere to pressure-treated woods because of the chemicals. Hence experts have recommended that pressure-treated woods be sealed or stained overpainting.

Features to look out for in a Deck Sealer before buying the best Deck Sealer for your Pressure Treated woods- Buyer’s Guide
- Sealant, Stain, or Both: Deck sealants come as a sealant, stain, or both. A sealant is usually a clear liquid, while a stain usually contains some color. For pressure-treated woods, sealants and stains come as clear liquid, semi-transparent liquid, and solid colors. Your preferences should be determined by the wood material you want to seal.
- Strength of Sealer: Sealers have different strengths. Your choice of a deck sealer should be determined by the conditions your wood deck is mainly subjected to daily. Premium versions of sealants are best suited for woods subjected to harsh conditions for maximum protection and durability.
- Age of Pressure Treated Woods: Some sealants like #1 Deck Premium Semi-Transparent Wood Stain for Decks, Fences, & Siding work best with an old wood surface to better absorb the sealant. The sealant should be formulated for your type of pressure-treated woods.
- Ease of application: The best sealant should be easy to apply and clean up. Some may require a roller, a paintbrush, while others may be compatible with a hand pump sprayer or low-pressure airless sprayer.
A water-based sealer is easier to clean than an oil-based sealer.
- Water Resistance: The best deck sealer should have the ability to resist water or moisture as water is the most critical enemy of woods. When water comes in contact with the wood surfaces with the best sealant, it will make water bead up, preventing absorption.
- Eco-friendly: A biodegradable wood deck sealer is a better option than a non-biodegradable sealant. When using a non-biodegradable sealant on exterior deck surfaces, a drop cloth can be used to cover nearby vegetation.
- Low or no VOCs: Pressure-treated woods are already embedded with chemicals. Choosing a low or no VOCs sealant is a great choice, especially for extensive pressure-treated woods. This is to prevent you from inhaling toxic fumes.
- Fast Drying Time: A fast-drying sealer should be chosen over a slow-drying sealer. A fast-drying sealer allows you to coat as many times as you want, quickly preventing you from inhaling harmful VOC fumes. It is also great in cases of unpredictable weather conditions over the next few days.
