Professional deck sealing is what Seal Smart is known for. We offer a 25-year warranty on our permanent sealant. We answer your frequently asked questions about deck sealing in today’s blog.

Should you seal your deck?

Yes, professional deck sealing extends the life of your wood deck while helping it to look more natural for longer periods of time. 

Does a wood deck need to be sealed?

Absolutely, because rot, insects, moisture, and weather can ruin your deck without it.

Is deck sealer necessary?

Yes, because professional sealing protects your wood against long-term deterioration from the effects of sun, rain, and temperature fluctuations. You should seal your deck even if you purchase pressure-treated wood.

What happens if you don’t seal your deck?

Several things happen over time to a wood deck that doesn’t have professional deck sealing.

You might see:

  • Graying
  • Splintering
  • Warping
  • Cracking
  • Rotting
  • Oxidation
  • Mold Build-Up

What is the best product to seal a deck?

You need a deck sealing product that doesn’t just cover the wood, but instead seeps into the wood. 

Seal Smart’s professional, one-time permanent penetrating deck sealant has a 25-year warranty because the product fills the pores and capillaries found in wood planks. Our product keeps water out of wood to prevent maladies associated with moisture, such as mold, mildew, and rot.

What time of year should I seal my deck?

Any season aside from winter is a great time for professional deck sealing services. That’s because Seal Smart’s product uses water to activate, and the process happens within minutes. Once the product seeps into the wood, it’s completely done. So long as the temperature stays at or above 40 degrees Fahrenheit, we can seal your deck even if it’s raining.

How often should I seal my deck?

With Seal Smart’s professional technology, you only need to seal your deck once in its lifetime. We’re the home of Never Seal Your Wood Deck Again, and we offer a 25-year warranty.

What happens if it rains after you seal your deck?

With Seal Smart, nothing happens to your wood deck at all. In fact, our professional deck sealing technology requires water to activate. So, let it rain! Once we apply our high-quality product, the rain will not affect your wood deck ever again.

What is the longest-lasting deck sealing product?

Seal Smart’s professional deck sealer lasts the longest with a 25-year warranty.

What sets deck sealing products apart from each other?

Most of the ones sold in stores simply sit on top of the wood without penetrating, thereby meaning you may have to re-do the process every three to five years.

Seal Smart’s proprietary deck sealant lasts for 25 years, which means you only need to seal your deck once in its lifetime.

How soon can Seal Smart seal your deck? 

Seal Smart’s team can complete professional deck sealing in an afternoon, generally from three to four hours, depending on the size. Do you have more questions? Reach out or give us a call at 1-877-288-6716, and we will be happy to answer any questions.
