Whether you never took a woodshop class or didn't pay a whole lot of attention in yours, you're in luck. Shop teacher from William E. Grady Career and Technical High School in Brooklyn, New York, Jose Santiago (a.k.a. Mr. Santiago) and HGTV veteran, Chip Wade, are teaching a refresher course.

From the right way to sand wood to the best type of hammer for beginners and more, the woodworking pros are breaking down the basics. 

Watch them make serving trays with Rach in the video above, and read up on the basics below before you take on your next DIY project. 

1. SAFETY COMES FIRST 

Always, always put on safety goggles before starting your woodworking project, our pros advise. 

"You want to be safe and you want to be comfortable," Chip says. 

Plus, "you're going to do your best work when you're not having to strain and reach for things," he continues — so set up your workstation wisely.

2. THE RIGHT WAY TO SAND WOOD

First off, Chip says that the best woods to use — for beginners, especially — are poplar and white oak. 

To sand, you can use a sanding sponge (Chip's favorite) or a sanding block, which is simply sandpaper over an ergonomic handle. Either way, the most important thing is that you have a flat hard edge to sand with. 

While sanding, you're going to want to do so WITH — or ALONG — the grain, Mr. Santiago and Chip explain.

See what they mean?

That's because if you scratch the wood against the grain, the imperfections will show when you stain it. 

3. USING A HAMMER CORRECTLY

One of the keys to nailing a nail properly is choosing the right hammer. 

Chip recommends a 16-ounce curved claw hammer. "Anything more than this is just too heavy," the HGTV veteran says. 

"I also recommend if you're going to get your first hammer," he continues, "get a smooth face, not a waffle face that looks like an ice cream cone." (Waffle face hammers are typically used to help grab picture-framing nails.)

Then, hold your hammer more towards the end, where there's a lip. Swing it loosely, Chip suggests, and get your wrist into it.

"I liken it to snow skiing," he explains. "If you're very timid when you're snow skiing, you're not going to be very good at it. If you're timid with your hammer, you're not going to be very good at it. You have to be confident."

And "focus on the nail head," Chip advises, "not the hammer."

4. HOW TO NAIL A NAIL WITHOUT HURTING YOURSELF

As for nailing, a very common mistake when starting a nail is to hold it down near the bottom, against the wood. This is wrong, because if you miss the head of the nail (and this might happen, especially if you're a beginner), the hammerhead will very likely crush your fingers against the wood. (Ouch!)

By holding the nail near the top, Chip explains, you have a bit more leeway and are less likely to hurt your fingers when mishaps occur. (Regardless, always be careful!)

5. THE ART OF APPLYING A PROTECTIVE COATING 

"Any good woodworking project has to have a protective coating," Chip says. It could be paint, but in the case of their serving tray, Chip and Mr. Santiago used a wood stain.

They stained their trays with a cloth — because when you paint it on, it floods the wood, making the wood grain rise.

"[The cloth] allows us to control the amount that's going on there," the HGTV star explains.  

So put gloves on, apply stain to our cloth — and wax on, wax off! (Wax off means wiping off the excess stain.)

Then, finish your project off with a polyurethane sealant OR a food-safe sealant if you're making a kitchen tool, like a serving tray.
