Anyone with a outdoor deck knows how great it is for entertaining guests. But those wood planks need to be treated sometimes to last longer. Those wood planks are susceptible to moisture. Either from rainwater or dew, the moisture can start your planks to rot. So treating your deck or sealing your deck is the best thing for it.
Treating the deck is a great weekend DIY project. All you need is a good oil based wood sealer. This will be applied after giving the deck a good cleaning.
Just make sure when you apply the sealer, you go with the grain of the wood.
If you feel you need a second coat, always wait until the first coat is dry.
