The strongest enemy of a smooth and seamless finish is dust. Don’t you know that blowing off the sanding dust through brushing or using an air compressor can still end up to a wet finish or stain? As a replacement for all these, grab a bristle and attach a vacuum on it. This helps you completely catch the dust on the material’s surfaces. This time, use a damp cloth to get rid of the lingering dust.
Painting Preparation: 5 Steps in Wood Cleaning After Sandpaper
Step 1: Blowing or Vacuum the Dust Off
First, you need to get rid of the sanding residue and sawdust. Use an air compressor. Make sure to fit a blower nozzle into the air compressor that you are planning to use. Also, use a vacuum to dust off each surface of the material. You might be asking how to manage your woodwork project’s crevices at this point. Trap all the tiny dust with a shop vacuum that has a high-quality filter. Such a filter is designed for this purpose.
There is no such thing as better vacuums. Vacuum cleaners with standard filters can work an excellent job in helping you dust off, especially on wood surfaces.
For the initial pass, it is recommended to use a shop vacuum. It can seize just about 95% of the dust particles on the surface. Thus, it helps you trim down the tediousness of cleaning the material surfaces amid sanding grits by half. Before moving on to the next level of sanding, get rid of bigger grit particles on the wood. As you notice, blowing the dust through compressed air can mix up the dust back into the surface. Therefore, you can breathe it once more.
Step 2: Wiping the Wood with Dry Clean Piece of Cloth
Right after dusting, make use of a clean, dry white cloth to wipe down the surfaces of the wood. A white piece of cloth lets you see the amount of dust you have wiped off.
Step 3: Cleaning the Corners through Brushing
The best way to blow off dust from a wood’s surfaces is brushing. A lot of woodworkers across the globe trust this process that much. They rely on the success of their project into such a method. Make sure to do it accurately by using more than one brush. Now, grab a soft large hand brush when you want to brush off larger wood surfaces. But, feel free to shift to smaller brushes or those that have stiffer bristles when you are working on smaller pieces of wood or areas.
Want to get into hard-to-reach corners, huh? That’s not a problem. Paintbrush can be a hero because of its size,, making it perfect for jobs on curves and corners.
Step 4: Tacking On
Never proceed with coating unless you have cleaned all the corners and surfaces of the material. A tack cloth is what you ever need this time. To define tack cloth, it is a type of fabric that looks like a cheesecloth. It is covered with layers of sticky adhesive. Furthermore, such a piece of cloth captures the last traces of dust on the surface (after all the dusting and vacuuming done). Never underestimate the value of tacking on because this last step is very essential to the entire process of pre-painting or wood preparation. Ascertain that no random cranny or dust is left in the wood before staining. Failure to do so can mess up your chance to achieve a blemish-free and gleaming woodwork project.
A tack cloth can be bought in local hardware stores at an affordable price. If you don’t want to purchase such tacking material, make your own. Have a 12″ cheesecloth soaked in tung oil (only a small amount). Then, seal and store it inside a plastic bag. This prevents tack cloth from getting dried out amid repeated uses.
Warped wood is not the real ‘threat’ here. Normally, wood needs to get soaked and remained wet to avoid the risk of deforming. Raised grain is the thing that you should feel nervous for. Raised grains are the swollen fibers on the wood surface that resulted from soaking up wood in water. However, this can be prevented by wetting the tack cloth with pure alcohol or acetone.
Step 5: Wiping the Surface with Denaturized Alcohol
For most woodworkers, a piece of wood is completely prepared for painting right after a tack cloth wipe-down. Only very few of these woodworkers do not end the process at this point. For these amazing few, wiping down the wood’s surfaces with a denatured alcohol-soaked cloth can help achieve the best results. Denatured alcohol, when spread on the wood, can pick up dust, including those finest ones. The fact that such a formula dissolves quickly into the air, wood discoloring is not possible. Moreover, it makes woodworking projects safer for use on wood projects that are used for serving food like that of a bread tray and chopping board.
Do you want to eliminate the remaining 5%? Well, here’s how. Wet tack cloths with solvent-based topcoat or dye. Water-based dyes or stains on a tack cloth is a no-no. You know microfiber cloths, don’t you? It works an exceptional job in “tacking “. Such material can be used without needing any formula to damp it. Therefore, you don’t fear surface contamination every time water-based, or solvent-based paints or coats are used. Lastly, you can use these microfiber cloths over and over again. All you need to do is take the clothes outside and wobble the dust off.
A piece of wood must be well-prepared for staining or coating. That’s the rule of the thumb. If you are re-staining old furniture, the very first thing that you need is strip off the old painting. There are quite a lot of stripping methods that you can use in your woodworking project.
As you reach this point, I’m sure that you have made yourself aware of the 5-step pre-painting preparation process. Once you’ve seen the amazing result of religiously following these 5-step process, you’ll start to use it as a standard procedure for your succeeding woodworking projects. Once you have completed the wood preparation procedures that I mentioned above, go ahead and proceed to the finishing or painting stage. Familiarity with these things can bring forth amazing results like fast and exceptional woodwork job.
