Garage Painting: Keep Dust At Bay

Keeping dust down in a garage while painting can be challenging, especially with concrete floors that are prone to dust accumulation. To effectively tackle this issue, it is essential to understand the sources of dust and implement preventive measures. Household dust arises from various sources, including pet dander, clothing fibres, dead skin cells, pollen, and particles from paint, wood, and building materials. Garages are particularly susceptible to dust due to external factors, such as dirt and grime blown in when the door is opened, and internal activities that generate dust and grease. To maintain a clean environment while painting, it is recommended to seal concrete floors with a high-quality sealant to prevent concrete dust. Additionally, regular cleaning with a push broom, dust mop, or microfiber cloth can capture dust and debris, while also ensuring that gaps and crevices are vacuumed to minimise dust buildup. Proper insulation and ceiling panels can also help to keep the garage dust-free. Upgrading garage doors and installing draught stoppers can further prevent dust and debris from blowing inside. Overall, a combination of sealing, cleaning, and organisational techniques will help create a cleaner, healthier environment for painting projects.

Seal concrete floors to prevent dust

Sealing concrete floors can help prevent dust and improve the safety of your industrial or commercial space. Before sealing your floor, it is important to ensure it is free of debris and loose particles. Here are the steps to seal your concrete floors effectively:

Firstly, use a vacuum cleaner to remove dust and dirt from the floor. Follow this by using a broom to reach corners and tight spots. It is crucial to remove all objects from the room or cover them adequately to prevent debris from falling on the floor during sealing. Protruding objects or fixtures should be covered with plastic or tape to protect them from the sealant.

Next, use a heavy-duty degreaser to clean any stains or grime that the vacuum and broom may have missed. This step is important as the sealant may not adhere well to greasy or oily surfaces. Ensure that the floor is completely dry before proceeding. If your concrete floor has rough or uneven areas, lightly sand them using a pole sander to create a smooth surface.

Concrete sealers or densifiers can then be applied to the floor. Concrete sealers, such as RadonSeal, can penetrate and chemically react with the surface, hardening it and eliminating concrete dusting. Concrete coatings, such as Armor-Tek 830, can also be used to lock in dust and completely stop concrete from dusting. Alternatively, a concrete densifier like Lithi-Tek 4500 can be applied to strengthen, harden, and reduce the porosity of the concrete, making it less susceptible to dusting.

It is important to note that commercially available floor sealing products may not penetrate concrete surfaces as effectively as industrial-grade sealers, resulting in reduced floor protection and durability. Regular cleaning and maintenance of your sealed floor are crucial to preserving its appearance and prolonging its lifespan. Reapplying the sealer every few years is recommended to maintain its effectiveness.

Use a broom, dustpan or mop to clean

Keeping dust down in your garage is important, especially if you spend a lot of time there. Dust can come from many sources, including pet dander, clothing fibres, dead skin cells, pollen, dirt, and particles from paint. While it is impossible to eliminate dust completely, there are several methods you can use to keep your garage cleaner and minimise dust while painting.

One simple yet effective way to keep dust down in your garage is to use a broom, dustpan, or mop to clean. Here are some tips to guide you through the process:

First, it is important to ensure that your concrete floor is properly sealed. Concrete that hasn't been sealed will start to decompose when exposed to moisture, oil, or grease, which can result in the concrete breaking down and producing cement dust. This dust becomes airborne every time you move across the floor. Therefore, before cleaning, check if your concrete floor needs sealing.

If your concrete floor is sealed and you're ready to start painting, use a broom or dust mop to capture most of the dust and debris on the ground. A push broom or a dust mop is particularly effective on unsealed concrete surfaces, as it prevents dust from becoming airborne while sweeping. Make sure to sweep away all the dust and debris before starting any painting work.

After sweeping, you can use a dustpan to collect the piled-up dust and debris. This ensures that the dust is completely removed from the garage and doesn't resettle on other surfaces. It is important to be thorough in this step to minimise the chances of dust spreading during your painting project.

Finally, consider using a mop to clean the garage floor. A microfiber mop can be especially effective at trapping dust and wiping down surfaces. Make sure to use a cleaning solution that is non-corrosive, as you don't want to damage the concrete. Alkaline cleaners or a mixture of bleach and water are good options to lift away dirt and oil stains.

By following these steps and using a broom, dustpan, or mop, you can effectively reduce the amount of dust in your garage and create a cleaner environment for your painting project. Remember to always wear protective gear, such as a mask and goggles, when working with dust to safeguard your health.

Reduce clutter to improve airflow

Reducing clutter is an effective way to control dust in your garage. Clutter provides more surfaces for dust to settle on, and it can also impede airflow, making it easier for dust to settle.

To reduce clutter, start by sorting items into three categories: donate, recycle, and throw away. Be ruthless—only keep items that you use and need. Utilize storage solutions such as slatwall panels, overhead racks, and storage cabinets to maximize wall and ceiling space and keep your garage tidy. With less clutter, you'll find it easier to clean your garage regularly.

In addition to reducing clutter, sealing your concrete floor can significantly reduce dust. Concrete that hasn't been properly sealed will start to decompose when exposed to moisture, oil, and grease, leading to concrete dust. Use a good quality sealant that penetrates the concrete rather than just floating on top. While floor paint is an option, it is notorious for chipping and flaking away and only offers a short-term cosmetic fix.

Other ways to improve airflow and reduce dust include insulating and sealing gaps in the ceiling, upgrading your garage door to eliminate draughts, and using an air purifier. By combining these strategies with regular cleaning, you can effectively reduce dust in your garage and create a healthier environment, especially if you use the space for hobbies or workouts.

Vacuum gaps and crevices

Gaps and crevices are dust traps and need to be vacuumed out occasionally to prevent dust build-up. Concrete floors are notorious for harbouring dust and grime, and the rougher the concrete, the more dirt it seems to attract. If your garage has a concrete floor, you will need to seal it to prevent dust from spreading throughout the room. Concrete that hasn't been sealed will start to decompose when exposed to moisture, oil, and grease, which will result in concrete dust that becomes airborne every time you move across the floor.

To prevent this, seal the concrete with a good-quality sealant that penetrates the concrete rather than just sitting on top. Products like RadonSeal or LatiSeal are recommended for this purpose. You can scrub the floor with a concrete grinder and then apply the sealant with a standard garden sprayer. Alternatively, you can mop the floor with diesel fuel, which will seal the concrete and prevent dust, although this method is not recommended due to the unpleasant smell.

Once your floor is sealed, you can help keep dust at bay by regularly sweeping, vacuuming, and mopping your garage. A push broom or dust mop is good for capturing dust and debris on the ground, and a microfiber mop or cloth is ideal for wiping down surfaces because they trap dust rather than just pushing it around. If you have a sealed concrete floor, be sure to use a non-corrosive cleaning fluid, as you don't want to break down the concrete. Alkaline cleaners are best, but bleach and water are also good for lifting away dirt and oil.

In addition to regularly cleaning your garage floor, you can reduce dust by decluttering the space and improving storage solutions. Less clutter means better airflow and fewer surfaces for dust to settle on. You can also prevent dust from blowing into the garage by sealing any gaps between the garage door and the door frame and upgrading your garage doors to eliminate draughts.

Use an air purifier to filter dust particles

While painting in your garage, you can use an air purifier to filter dust particles and improve the air quality. Painting can fill the air with airborne particulates, which can be especially bothersome for those with asthma or allergies.

Air purifiers such as the EnviroKlenz Mobile Air System are designed to trap and neutralize volatile organic compounds (VOCs) as well as dust, mould, pollen, and other airborne allergens. It features a high-efficiency particulate air (HEPA) filter that can trap and remove 99.99% of all airborne particulates over 0.3 microns in size. HEPA filters are highly effective at capturing fine particles, and their efficiency increases with smaller particles.

For garage systems, HEPA filtration is an excellent choice for removing very fine particles, such as smoke, fabric fibres, and paint particles. LakeAir manufactures electrostatic filter cells that are designed to last for 15 or more years, although they are not as efficient as HEPA filters.

To minimize health risks, it is recommended to turn on the air purifier before starting to paint and let it run throughout the entire painting process. Additionally, consider using low- or zero-VOC paints to reduce exposure to toxic fumes.
