Dyeing Wood: Rit And Alcohol Method

how to dye wood with rit and alcohol

Rit Dye is a simple and inexpensive way to dye wood in a variety of colours. It is easy to apply and does not have strong fumes like oil-based stains. Rit Dye must be applied to unfinished wood, so if your wood has a finish, you will need to strip it. When mixing Rit Dye, you can use water or alcohol. Alcohol-based dyes will penetrate deeper than water-based ones and will not raise the grain as much. To mix Rit Dye with alcohol, use one part Rit Dye, six parts 99% isopropyl alcohol, and two parts water (for liquid dye only). Stir until mixed and use a coffee filter to filter out solids if desired.

Preparing the wood

To prepare wood for dyeing with Rit Dye and alcohol, follow these steps:

Firstly, decide on the type of wood you will be using. Softwoods, such as pine, are porous and absorb dye more easily, whereas hardwoods, like oak and maple, are less porous and may require more coats of dye. If your wood is unfinished, lightly sand it with sandpaper and wipe it clean. If it is finished, you will need to strip any paint, varnish, or wax from the item. Use a scraper to remove the finish, then sand the surface until smooth. After sanding, wipe the wood clean with a tack cloth to remove any remaining dust.

Before dyeing, it is important to test the colour on a scrap piece of similar wood or a hidden area of your item. This will allow you to adjust the colour as needed before applying it to the entire surface. If the colour is too light, add more dye, and if it is too dark, add more water or alcohol. Rit Dye can be mixed with either water or alcohol, but using alcohol will prevent grain-raising and allow for deeper penetration of the dye.

If you are aiming for a softer look, wet the wood and let it dry for about 15 minutes before dyeing. This will help achieve the desired effect. Additionally, if you are stencilling a design, tape the stencil in place and dip a stencil brush into the dye, blotting it on a paper towel until nearly dry before applying.

Mixing the dye

When mixing Rit dye with alcohol, it is important to note that the dye must be applied to unsealed, unfinished wood. If your wood has a finish like polyurethane, varnish, or wax, you will need to strip it and sand the surface until smooth before applying the dye.

For mixing the dye, you can use either Rit powdered or liquid dye. If using the liquid dye, you may need to experiment with different types of alcohol. Some sources mention that 99% isopropyl alcohol does not mix well with the liquid dye, resulting in the two liquids separating. In such cases, you may need to try a different type of alcohol, such as denatured alcohol or rubbing alcohol.

The general ratio for mixing Rit dye with alcohol is 1 part dye to 6 parts alcohol. For liquid dye, add 2 parts water to this mixture. You can stir the mixture until combined, but be aware that powdered dye may still have some salts at the bottom, and liquid dye may have some unmixed clumps. If desired, use a clean, unused coffee filter to filter out any solids.

It is important to note that homemade alcohol ink made with Rit dye may not be as concentrated or vibrant as commercial brands. Additionally, alcohol-based dyes will not raise the grain as much as water-based dyes, and they will penetrate deeper into the wood. Always test your dye on a scrap piece of wood first to ensure you are happy with the colour and penetration.

Finally, remember to wear gloves and protect your work area with a plastic cover or newspaper before beginning the dyeing process.

Applying the dye

When applying the dye, it's important to note that Rit Dye must be applied to unsealed, unfinished wood. If your wood has a finish, you'll need to strip it before applying the dye. Cover your work area with a plastic table cover or newspaper to protect against spills, and have paper towels on hand. Wear gloves and, if necessary, lightly sand unfinished wood and wipe it clean with a tack cloth.

For the dye mixture, mix 1/2 cup (120 mL) of liquid dye or 1 box of powder dye with 2 cups (470 mL) of very hot water. You can adjust the colour by adding more dye or water. If you want to create a softer look, wet the wood and let it dry for 15 minutes before dyeing.

You can apply the dye with a foam, bristle brush, or old cloth, spreading it evenly over the surface. If you're using a stencil, tape it in place, dip a stencil brush into the dye, and blot on a paper towel until it's nearly dry. Start at the outside edges and brush towards the centre of the stencil. Wait 1-2 minutes for the dye to absorb, then remove the stencil.

If you're using alcohol with your Rit Dye, the process is a little different. Mix 1 part Rit Dye (powdered or liquid) with 6 parts 99% isopropyl alcohol (rubbing alcohol) and 2 parts water (for liquid dye only). Stir until mixed, and use a clean, unused coffee filter to filter out solids if desired. Apply this mixture by wiping it onto the wood.

Let the dye dry completely before deciding if you need to apply another coat to achieve your desired shade.

Drying and sanding

After applying the dye, it is important to let the wood dry completely. If you are not satisfied with the shade, you can apply another coat of dye. Once you are happy with the colour, you can start the process of drying and sanding.

Firstly, apply one or two coats of polyurethane using a new foam or bristle brush. Then, lightly rub the wood with steel wool or #220-grit fine sandpaper between coats. Remove any dust and filings with a tack cloth. If you are using Rit Dye on a woodturning project, you can finish the wood with CA glue after lightly sanding it. Alternatively, you can use a spit-coat of dewaxed shellac to prevent leaching into the finish layer.

If you are working with finished wood, you should strip paint, varnish, or wax from the item. Scrape and sand the surface until it is smooth. Then, wipe the surface clean with a tack cloth.

If you are using Rit Dye on a porous wood, you may want to apply a wood conditioner before the dye to reduce blotchiness. You can then lightly sand the wood with #220-grit sandpaper and remove the sanding dust with a tack cloth.

It is important to note that Rit Dye is not light-fast and may fade quickly. To prolong the colour, avoid placing the dyed wood in direct sunlight or under fluorescent lighting for extended periods.

Sealing the wood

Choose the Right Sealer

It is important to choose a sealer that is compatible with the dye and the type of wood you are using. If you are using a water-based dye like Rit Dye, an oil-based sealer is usually the best option. Oil-based sealers, such as polyurethane, do not interact with water-based stains and dyes, so they will not lift or remove the dye from the wood.

Apply a Barrier Coat

Before applying an oil-based sealer, it is recommended to first apply a coat of wax-free shellac or a sanding sealer. This acts as a barrier between the dye and the sealer, preventing any unwanted interactions. The shellac should be dewaxed to prevent leaching into the finish layer. You can thin the shellac with alcohol to create a suitable barrier coat.

Spray or Wipe-On Application

The method of application depends on the project and your personal preference. Spraying the sealer is often the best option, as it is less likely to lift the dye from the wood. However, if spraying is not feasible, you can carefully wipe on the sealer with small paper towels or a foam, bristle, or stencil brush. Be gentle and use light strokes to avoid disturbing the dye.

Multiple Thin Coats

When applying the sealer, it is generally recommended to apply multiple thin coats rather than one thick coat. Thin coats dry faster and allow you to build up the finish gradually, resulting in a smoother and more even finish. Sand the wood lightly with fine-grit sandpaper between coats to ensure a smooth surface and remove any raised grain.

Final Steps

After applying the desired number of coats and allowing the sealer to dry completely, you can finish the wood to your desired sheen. You can use steel wool or fine sandpaper to create a rustic or polished look, depending on the level of sheen you want to achieve. Finally, you can apply a wax or oil to enhance and protect the finish.
