How to Use Gel Stain on Wood

Staining wood is the best way to get a natural look while altering the color or bringing out the grain pattern. Since stain products soak into the wood and offer a translucent color rather than the opacity of paint that sits on the surface, they’re much more flexible in how they look when finished. Yet, it’s also a little trickier to apply a stain product since it begins soaking in immediately, and adding another coat darkens the color. 

Step 1: Prepare the Surface

One major benefit of choosing a gel stain is reducing the preparation of the surface. Liquid stains must soak in well, so they must be applied to wood that was sanded down to a raw surface. Gel stain is easily applied over a surface that is only lightly sanded, even if it was previously painted or is a non-porous material like metal. It’s possible to leave cabinets, doors, and other items installed vertically in place during application with relatively few drips and streaks. However, remove what materials you can to stain them horizontally for maximum control over the application.

Step 2: Apply Gel Stain to Wood

Shake, then stir the gel stain until it is smooth and slightly thinner than it started. Each product varies in the final consistency, but it tends to vary between syrup and a runny gel. Check the product’s instructions for more information on what to look for to verify complete mixing.

Wear rubber or nitrile gloves to protect your hands.  Simply use the paintbrush or a cloth wrapped over your fingers to spread an even layer of the gel stain over the surface that needs color. Don’t work it into the surface too hard, or it could result in uneven coloration. Use a lint-free cloth to dab up any excess stain that has accumulated in crevices, along edges, or where the stain has dripped.

Step 3: Cleanup after Using Gel Stains

Unlike water-based stains that are often easily cleaned up with soap and water alone, gel stains need mineral spirits for cleanup. Clean any spilled or dripped stain immediately with the mineral spirit to prevent staining. Use a canvas or plastic drop cloth where you’re working to protect flooring, countertops, and other materials. Take furniture and small objects outside for easy staining. It’s possible to use a brush dipped in mineral spirits and then dried down to damp with a rag to even out areas of gel stain that are too thick and have started to dry. However, streaking can worsen from too much attempt to even the finish, so settle for natural variations based on how the gel dries.

Step 4: Sealing Gel Stain

Gel stain sits on the surface, much like paint. So it needs to be protected by a sealant over the surface. Polyurethane is a common choice available in both matte and glossy options. Shellac, varnish, and even epoxy-based clear sealants can work well. Choose a sealant based on its protectiveness of the surface and the finished look it offers.

Practice with small wood objects like picture frames or old cabinet doors to develop your gel stain application skills. More forgiving to work with than liquid stain, these thicker products give you new opportunities to create finishes that are somewhere between the full translucency of liquid stain and the opaque look of paint.

How to Use Gel Stain on Wood FAQ’s

Wood finish vs gel stain

What is Gel Stain?

Gel stains are an alternative to the usual liquid stains that aim to make even application a little easier due to a thicker texture that spreads more easily. They’re also more versatile, working well on materials like metal, Masonite, and even previously painted surfaces. Figure out if gel stain is right for your project with this guide to preparing for and using it.

What is the difference between Gel Stains vs. Wood Stains?

Both stains are available in most colors, but they vary the most in texture. Gel stains are thicker and spread easily across less porous surfaces. Liquid stains work well on porous materials like wood, but they don’t absorb well into painted or metal surfaces. The gel does less to bring out the wood’s natural grain. This can be good for smooth materials like hardboard or Masonite that lack a texture to bring out. Gels aren’t quite as thick as the name might suggest once they’re properly mixed, but they’re usually as thick as oil and far more viscous than water-based liquid stains. However, this also makes cleanup a little more work at the end of the project. And as with all stains, you can only darken the wood and must start with sanded or bleached surfaces to get a lighter finish.

How Long Does it Take For Gel Stain to Dry?

Apply subsequent layers of gel stain after the initial coat has a chance to dry fully. This can take 8 to 24 hours, depending on the product and the humidity level. Use a thinner layer of the stain for second and third coats, buffing it on with a cloth rather than a brush. This builds the color without leaving brush marks that create a paint-like look.

Can You Paint Over Gel Stain?

Yes, you can paint over gel stain, but there are specific steps you need to follow to ensure the paint adheres properly and the finish is smooth and durable. You will need to clean and sand the surface first. Then, remove any dust before you apply a primer. If you don’t need to sand again, then you can go ahead and paint the surface before finishing with sealing the paint.

Start by thoroughly cleaning the door to remove any dirt or grease, then lightly sand the surface to ensure the stain adheres properly. Wipe away any dust with a tack cloth. Using a brush or a clean cloth, apply the gel stain in even strokes, following the grain pattern if present. Work in small sections to maintain a wet edge and avoid lap marks. After allowing the stain to set for a few minutes, wipe off the excess with a clean, dry cloth, working in the direction of the grain. Allow the stain to dry completely, and apply a second coat if a deeper color is desired. Finish by applying a clear sealer to protect the stained surface.

What is the Best Tool to Apply Gel Stain?

Unlike with liquid stain, using a fine bristle paint brush is acceptable to apply gel stain since it’s applied much more thickly. 

How do you Apply Gel Stain without Streaks?

You’ll need a lint-free cloth to dab up drips, streaks, and thick areas while the gel is drying.
