In this week's Do It Yourself Tip, Jeff Hinz from Kirkwood Ace Hardware tells us about water seals and stains when treating your new or old deck.
So let's start with water seal, there are many of them the truth about this is that it is a gallon of paint thinner but they add paraffin wax so when you paint it on a piece of wood, most of the paint thinner dries away into the air. Water does bead up, but you have done nothing to help the wood from drying out. We don't recommend this for your deck. What we want to do is replace the moisture which is coming out of the wood.
We want to try and load the wood with oil. There are a lot of new water based stains on the market they will not replace the moisture. They will give yo a surface treatment and bead up the water, but nothing soaking into the wood. Even when we get more oil based stains, there's a not a lot of oil in the product. You can see pigment but most of the rest of the stuff is just paint thinner. And then when you get a better quality you can see the oil content improving. When you get to a premium product, you see that it is all oil. That's why each of these in succession cost more money. You are truly getting exactly what you pay for.
We have had some complaints of people staining their deck and then going back a few days later and putting another coat of stain on there. The problem with that is the stain is dry and if you add another coat, it will actually repel the product and you will have a sticky mess.
Also we recommend using a real brush, not a roller of synthetic brush. If you use a roller it will add too much product and if you use a nylon brush, the product will actually melt the bristles together and you will end up using something like a brick to finish your project.
