Best Gel Stain for Wood and Fiberglass: At a Glance

What is a Gel Stain? 

A gel stain is a wood stain designed to be thicker and more dense than traditional liquid stains. 

The best gel stain is typically used to add color to wood surfaces while providing some level of protection and enhancement to the wood’s natural grain.

The thicker consistency of gel stains also means they provide greater control and better coverage during application.

Types of Gel Stains For Wood And Fiberglass

Various types of gel stains are available on the market, each with unique characteristics and applications. Understanding the different types of gel stains can help you choose the right one for your project.  

  1. Oil-Based Gel Stains:

These stains are known for their durability and rich color. They provide deep penetration into the wood, enhancing the grain and natural beauty.

Due to their long-lasting finish, oil-based gel stains are ideal for larger projects and outdoor applications. They require a longer drying time compared to water-based stains.

  1. Water-Based Gel Stains:

Water-based gel stains are eco-friendly and emit fewer fumes, making them suitable for indoor use. They have a quicker drying time than oil-based stains.

While they may not penetrate wood as deeply as oil-based stains, they still provide a lovely finish. Water-based gel stains are easier to clean up with water and soap.

  1. Gel Stains with Polyurethane Finish:

These gel stains combine the staining process with a protective polyurethane finish. They save you time and effort by eliminating the need for a separate topcoat.

Gel stains with polyurethane finish offer excellent durability and resistance to wear and tear.

  1. Gel Stains with Gel Topcoats:

Some gel stains come with a matching gel topcoat. These stains and topcoats are designed to work together for a harmonious finish. They provide enhanced protection and a consistent look.

  1. Gel Stains with Color Blending Options:

These innovative gel stains offer the flexibility to blend different colors, allowing you to create custom shades. They are perfect for creating a unique and personalized look on wood or fiberglass surfaces.

  1. Opaque Gel Stains:

Opaque gel stains are designed to completely cover the surface, hiding the underlying wood or fiberglass grain. They are often used when you want to change the color of a piece entirely.

  1. Transparent Gel Stains:

Transparent gel stains allow the natural beauty and grain of the wood or fiberglass to show through. They provide a more subtle and nuanced finish, enhancing the existing characteristics of the material.

  1. Specialty Gel Stains:

Specialty gel stains may include metallic finishes, glitter-infused stains, or distressed finishes. These stains cater to specific design preferences and creative projects.

  1. Low VOC Gel Stains:

Low VOC (Volatile Organic Compound) gel stains are environmentally friendly and emit fewer harmful chemicals. They are a responsible choice for those who prioritize indoor air quality and sustainability.

  1. Exterior Gel Stains:

These are gel stains designed for outdoor use. They are formulated to withstand the elements, including UV rays, moisture, and temperature fluctuations.

They provide long-lasting protection and color retention for outdoor wood and fiberglass surfaces.

Gel Stains Vs Regular Stains: What’s The Difference? 

Both gel stains and regular stains can achieve beautiful finishes when used appropriately, but the choice between them depends on the specific project, the type of wood, and the desired application method

Gel stains are often preferred for their ease of use and reduced risk of blotching, especially on blotch-prone woods like pine. On the other hand, regular stains are favored for their quicker drying time and versatility in certain applications.

Here is the difference between gel stains and regular stains in depth. 

  1. Consistency

Gel stains are thicker, gel-like, and similar to pudding or mayonnaise. This thickness makes them easier to control during application and reduces the risk of dripping or running.

Regular, liquid stains are more fluid and have a thinner consistency, similar to water or paint. They can be more challenging to control and may drip or run if not applied carefully.

  1. Application

Gel stains are typically applied using a brush, rag, or sponge. Their thickness allows for precise application, making them suitable for vertical surfaces and intricate woodwork.

Regular, liquid stains are often applied with a brush, cloth, or foam applicator. They require more careful handling to prevent uneven coverage.

  1. Blotching

Gel Stains: Gel stains are less prone to blotching or streaking on wood surfaces, especially when dealing with porous or uneven-grain woods like pine or cherry.

Regular Stains: Liquid stains can sometimes result in blotches or streaks, particularly on certain types of wood unless a pre-stain wood conditioner is used.

  1. Drying Time

Gel stains tend to have a longer drying time compared to liquid stains. This can be an advantage for projects where extended working time is needed.

Regular wood stains typically dry more quickly, which can be advantageous for faster turnaround projects.

  1. Customization

Gel stains can be mixed with other gel stains or thinned with a compatible thinner to create custom colors or adjust the thickness for specific applications.

Regular wood stains can also be mixed to create custom colors but are typically used at their original consistency.

  1. Grain Raising

Gel Stains: Gel stains are less likely to cause significant grain raising in wood surfaces due to their thicker consistency.

Liquid stains can sometimes cause wood fibers to swell, leading to more noticeable grain raising. This characteristic applies to water-based wood stains

Advantages of Gel Stains over Liquid Stains 

Gel stains are typically preferred for certain woodworking projects, such as finishing blotch-prone woods and fiberglass, because they offer several advantages, including the following. 

  • Gel stains are easier to control and apply compared to liquid stains. Their thicker consistency makes it less likely for the stain to drip or run, allowing for more precise application. 
  • Gel stains provide better coverage. When applied to wood, they tend to create a more even and uniform color, reducing the chances of blotching or streaking.
  • Gel stains are more versatile. They can be used on both porous and non-porous wood surfaces, making them suitable for various woodworking projects, including furniture, cabinets, and decorative items.
  • Gel stains offer reduced grain raising. When wood absorbs liquid stains, it can sometimes cause the wood fibers to swell or rise, leading to a rough texture. Gel stains are less likely to cause significant grain raising.
  • Gel stains reduce blotching. Gel stains are less prone to causing blotches or streaks on wood surfaces, even on porous or uneven-grain woods like pine or cherry. This makes them an excellent choice for achieving consistent and uniform coloration.
  • Gel stains are excellent for vertical surfaces. Gel stains are well-suited for staining vertical surfaces, such as cabinet doors or paneling, where maintaining control and preventing drips is crucial.

Choosing the Best Gel Stain for Wood and Fiberglass

When selecting the best gel stain, consider the following factors:

Color Options

Different gel stains come in various colors. Whether you prefer a classic walnut finish or a bold ebony, there’s a gel stain to match your vision.


Some gel stains offer more transparency than others. The level of transparency affects how much of the wood grain will show through the stain. Make sure to choose one that aligns with your desired look.

Surface Compatibility

Not all gel stains are suitable for both wood and fiberglass. Ensure the product you choose is compatible with your project’s surface material.

Application Technique

The method of application can vary between gel stains. Some are best applied with a brush, while others work well with a rag. Follow the manufacturer’s instructions for the best results.


Think about how long the product will last. To make sure the finish holds up over time, try to find a gel stain that is resistant to fading, flaking, and chipping.

Environmental and safety considerations 

Think about how your actions will affect the environment and safety. Find products with low volatile organic compound (VOC) levels that won’t harm you or the planet. Safer and less harmful to the environment are water-based gel stains.

Your budget

Prices for gel stains vary widely, so it’s important to set your budget based on the available options and go for a product that won’t break it. 

Notice that a higher price tag may go with a better quality product. However, you must balance between quality and price. Consider looking through the user reviews to learn about the real-life experiences of people who have used the product before you. 

How to Apply Gel Stain on Wood and Fiberglass Step by Step

Gel stain can be a game changer if you want to rejuvenate the appearance of your wooden or fiberglass surfaces. This step-by-step guide walks you through applying gel stain like a pro.

What You’ll Need

  • Gel stain in your preferred color
  • Sandpaper (various grits)
  • Clean, lint-free cloths
  • Brushes or foam applicators
  • Painter’s tape
  • Drop cloths or newspaper to protect your work area

Step 1: Surface Preparation

Proper surface preparation is crucial for achieving a flawless finish.

Begin by sanding the surface to be stained. Use a coarse-grit sandpaper (around 80-120 grit) to remove any existing finish or imperfections. Follow up with finer grits (150-220) to create a smooth, even surface.

After sanding, wipe down the surface with a clean, damp cloth to remove any dust or debris. Let it dry completely before proceeding.

Step 2: Testing the gel stain

Before applying the gel stain to your entire project, it’s a good idea to do a test on a small, inconspicuous area. This allows you to assess the color and how it interacts with your wood or fiberglass.

Step 3: Applying the Gel Stain

Now, it’s time to apply the gel stain and bring your project to life. 

Start by thoroughly stirring the gel stain. This ensures an even distribution of pigments and consistency.

Using a brush or foam applicator, apply the gel stain in long, even strokes, following the grain of the wood or fiberglass. Work in small sections to ensure you have control over the application.

Step 4: Wiping Off Excess Stain

After applying the gel stain, it’s crucial to wipe off any excess.

Let the gel stain sit for a few minutes, typically 3-5 minutes, but follow the manufacturer’s recommendations for your specific product.

Then, using a clean cloth, gently wipe off the excess stain in the direction of the grain. Be sure to maintain consistent pressure to achieve an even finish.

Step 5: Drying and Additional Coats

Allow the first coat to dry completely, typically within 6-8 hours. You can then decide if additional coats are needed to achieve your desired color intensity. Repeat the application and wiping process as necessary, allowing adequate drying time between coats.

Tips for Applying the Best Gel Stain on Wood and Fiberglass

Achieving a flawless finish with gel stain requires proper application techniques. Here are some tips to help you get the best results:

  • Prepare the Surface. Before applying gel stain, ensure the surface is clean and free of any dust or debris. Sand the wood lightly along the grain to create a smooth surface for the stain to adhere to.
  • Test on a Sample Piece. If you’re unsure about how the gel stain will look on your project, it’s a good idea to test it on a small, inconspicuous area or a scrap piece of wood. This allows you to see the color and transparency before committing to the entire project.
  • Apply Evenly. Use a brush or rag to apply the gel stain evenly, following the grain of the wood. Be consistent in your strokes to prevent streaks or uneven coloring.
  • Wipe off the Excess. After applying the stain, wait a few minutes (follow the manufacturer’s instructions) and then wipe off any excess stain with a clean cloth. This step ensures an even finish and prevents blotching.
  • Allow for Drying Time. Gel stains typically require longer drying times compared to liquid stains. Be patient and allow each coat to dry completely before applying the next one.
  • Seal the Finish. To protect and enhance the appearance of your stained surface, consider applying a clear polyurethane or varnish after the gel stain has dried. This will add a layer of protection and a beautiful sheen to your project.
  • Clean Up Carefully. Gel stains can be challenging to clean once they dry. Use mineral spirits or the recommended cleaning solution for the specific gel stain brand to clean your brushes and applicators.
