Why Is Painting Your Basement Important?

Often people ignore taking care of their basements, and the key reason is that the basement is not initially visible to people who visit their home. A basement is a kind of secret room that has numerous utilities.

Generally, a basement is used for those activities for which you don’t want any room in your main house. People use it as a store, gym, tool house, laundering area, mega-media room, or even game room. Therefore, maintenance is equally essential as the other rooms of your house.

The exterior and interior need to be painted after a regular interval, and this rule is also applicable for the basement area. IThe floor tolerates tons of dust and pollution every day, and painting the floor would be a wise decision to enhance its aesthetic beauty and durability.

However, you can’t do it anyway because not many people will be going to see it. You have to take equal care while painting the floor because it will add value to your home and keep it under maintenance.

Therefore, make sure you follow all the steps to paint your basement. Let’s start with some key initial arrangements.

Choosing The Right Paint

First, you need to choose the right paint. Suppose can’t be any paint that is available in the market. Floor paints are always different from all other paints because it is exposed to maximum wear and tear.

Therefore, while choosing the paint, you will need enough research and expertise; otherwise, all your efforts of painting the floor and your money to purchase the tools and the paint will be in vain – because it will not last a month if you do not make the right decision.

If you are confused about the available options, you can always reach out to a professional; however, our below guide will hopefully help you out.

Most Available Market Paints

Buying floor paint from a home improvement store sounds like the most straightforward approach, especially for a bit of striping project. However, commercial and industrial floors are subjected to a lot of foot and mechanical traffic, and this type of paint is unlikely to be able to withstand it!

If you don’t, you may wind up having to redo the whole thing within a few months, which will lead to greater expenditures in the long run. Latex and water-based paints are less durable and more susceptible to chemicals, dampness, and other environmental aggressors.

For flooring, epoxy- or polyurethane-based paint is typically preferred. Also, keep in mind that while do-it-yourself painting may look good in the privacy of your own home, it can look downright amateurish in a warehouse or manufacturing facility.

You’ll save time and money by hiring a professional if you don’t have years of painting expertise.

Industrial-Strength Paint

You can also hire an industrial painting contractor to provide a more robust paint kind for industrial floors. It is unnecessary to hire a professional to perform the job (because we will guide you) unless you are reluctant to invest your time and effort into it.

Corrosion resistance and increased durability are two examples of specific qualities that may be included in industrial paint. Suppose you’re painting a significant part of the floor. In that case, it’s best to hire a professional contractor, as even a minor mistake such as letting the paint cure at the wrong temperature can result in wasted time and money.

Epoxy Coating

One of the main advantages of a two-part epoxy floor coating system is that it provides an extra-sturdy finish without paint but it also has some cons too that you can read here. There are a variety of hues and patterns to choose from, including a metallic sheen and crushed quartz.

In addition to being water-resistant, epoxy coatings also resist abrasions, impacts, wear and tear from foot traffic, and routine cleanliness. Unlike paints, you can use a water-based epoxy for an industrial floor without fear of it breaking down.

On the other hand, professional-grade paints often contain between 90 and 100 percent solids by volume, whereas the epoxy paints available at home improvement stores typically contain between 30 and 70 percent solids by volume.

Suppose you choose to use an epoxy contractor. In that case, they will adequately prepare your floor and ensure that the coating is applied in the proper environment, resulting in fewer bubbles, blisters, and other bonding failures.

Safety Precautions

Keep in mind that you will be exposed to chemicals. Yes, paints are compounds of harmful chemicals. Provided you are opting for a DIY method to paint your basement; you can’t afford to skip the safety measures that will help you prevent all possible hazards. Here are some standard safety measures that you must take before you start the final job. Take a look.

Adequate Ventilation Is Important

If you’re painting with solvent-based paint, be sure you have adequate ventilation. The National Capital Poison Center reports that solvent paints produce vapors that can induce headaches, dizziness, and nausea.

While painting a room that lacks ventilation, these issues are more likely to arise. Doors and windows should be opened to avoid these potential threats. You’ll be able to work longer in a room that’s been adequately ventilated. This will provide for a cross-breeze that circulates air by preventing you from inhaling too many paint fumes.

Make sure the room’s fan is running if it has one. Wearing a respirator is also a good idea. A painter’s mask from a hardware store or local building supply will work just as well as more expensive oxygen equipment.

Take Care Of Electrical Outlets

Use painter’s tape to cover all exposed electrical outlets while working with your painting job. Before you start, turn off the electricity in the space where you’ll be removing the outlet or outlet covers.

Personal Safety Gear

When solvent paints, cleansers, and strippers are directly exposed to the chemicals, they can irritate the skin and eyes. Invest in some personal protective equipment, such as goggles and gloves.

A long-sleeved shirt may also help protect your arms from being splashed in the face and neck. To avoid your hair and scalp from being irritated, use an old hat or cap to cover your head.

If you don’t have proper safety gear, don’t start the job ignoring the chance for possible hazards. Accidents can happen anytime, even if you have years of experience in painting work.

Preparation For Painting A Basement Floor

Before starting to paint the floor, you must need some preparation to get the maximum of your efforts. If you avoid this part, there is a high chance that you can’t do the job properly, and the ultimate look doesn’t seem to be satisfying.

To get the desired outcome from this DIY method of painting your basement floor, make sure you abide by the preparation guide:

Remove Moisture From The Floor

Basement is the area of your house that is completely deprived of sunlight. Hence, it is possible to be a little damp. To ensure if the floor has humidity or not, you can tape a piece of plastic on the area and let it be there for at least 24 hours.

If any part of the plastic seems moistened the next day, know that it is coming from the floor. If the floor appears to be wet, you should investigate further. If this is the case, you’ll need to take care of moisture-related issues first.

You can’t use basement floor paint on wet or moist concrete because it will blister and peel off right away. Use a dehumidifier to remove moisture from the floor.

Remove All Dust & Dirt

Clean the basement floor by sanding it. This also helps the basement floor paint adhere to the concrete because the pores of the concrete have been opened up.

If the floor has an uneven area, sanding can fix this up, and also, in case of old paint, sanding can remove that too. If the floor is too smooth, this method will roughen it up to absorb the new layer of paint more quickly.

After the grinding and sanding, thoroughly vacuum the floor to eliminate any remaining dust, filth, and debris. After vacuuming, moisten a microfiber mop with denatured alcohol and use it to wipe down the floor.

Remove any leftover fine dust particles by scrubbing the surface. Before you begin painting your floor, you’ll need to remove any prior coatings, paint, or sealers.

Repair Chips Or Cracks

To use basement floor paint, you must first repair any gaps in your floor. DIY concrete crack repair kits are easy to use and will fill and seal any concrete floor cracks.

You can also fill the cracks and chips with compounds and push them into the cracks to get an even surface. Here are some steps you can follow:

  • Scrub the cracks and remove any loose material with a wire brush.
  • Make sure there are no stains of oil or grease near the crack. To remove oil or grease, you must thoroughly clean the area.
  • Undercut the sidewalls of the cracks with a hammer. Make sure you wear the goggles while doing the job. Using an undercut offers the sealant a stable base.
  • Apply a coat of appropriate adhesive to the crack with a bit of paintbrush and wait for it to cure.
  • According to the manufacturer’s instructions, mix an adequate amount of the sand mix.
  • Use a trowel with a smooth surface to fill in the crack and level the surface.
  • Ensure that your patch filler has cured overnight or for the length of time indicated by the manufacturer.
  • The patch should be examined once it dries to see whether it needs any more filling.

However, if you are not confident about this area, you must call a professional to perform the repair job.

Apply Tapes Wherever Necessary

To avoid all possible mess with the paints, you must do the taping. Tape all those areas you don’t want to be exposed to paints, including the bottom of your walls, fixtures, baseboards, etc.

It may be time-consuming if you are a novice, so it is better to use painter’s applicator tape to speed it up. Use the toll of tape that you can easily find in the hardware store.

Add Primer

Make sure the surface is dry, clean, and free of loose or flaking paint before you begin. To remove excess alkalinity from newly poured concrete, you’ll need to wait at least four weeks before applying concrete etchant.

Oil & Grease Remover will get rid of any oily residue on your surface. If you must wash the concrete, allow it to dry before applying Primer so that it can penetrate.

Epoxy Repair Mortar, developed for concrete surfaces, can be used to repair surface damage. If the floor temperature is below 10°C, experts do not recommend applying Primer. Curing agents and resin are included in the 2.5-liter package.

Make sure you mix the contents of both tins thoroughly before transferring them to the larger container and then do the same with the smaller one. Use right away if the mixture hasn’t been properly mixed.

If you don’t apply it within an hour, it will be rendered useless. You can use a brush or roller to apply it to the surface and work it in well. Ideally, the seal should be applied in temperatures between 15°C and 25°C. The drying process will take longer at lower temperatures.

When the weather is dry, warm, and well-ventilated, you’ll get the best results. The drying period will be roughly 4-6 hours at the temperature of 15°C or above. Lack of ventilation can increase dampness and low temperature.

Apply Epoxy/Paint

You’ve probably been working on painting your basement floor for a few days now. The first coat should go on smoothly if the previous stages were followed correctly.

First Coat

The first coat is typically used as a technique to reveal the floor beneath. The first coat of pigmented epoxy will reveal the true substrate’s condition. This is the time to look for any lingering cracks and holes!

You can use a roller to apply the initial layer, depending on what you want. If your floor has numerous dents and microscopic holes, you should use a squeegee to apply a filler coat as the initial step in the resurfacing process.

Empty the hardener in component A of all its contents when you’re ready to begin coating. Mix for at least two minutes with an electric mixer. Don’t cut corners when it comes to mixing! This is a critical stage. A sticky floor is a sure sign of poor mixing.

You must ensure that you have enough help for the surface you’re working on. Because epoxy has a short pot life, applying it on your own is not recommended. To expedite the floor painting process before the pot becomes unusable, always have a helper on hand.

Use a high-quality roller if you’re using a roller to apply your paint. Paintbrushes and masking tape are also helpful for dealing with the edges of your project.

Sanding & Filling

Once the first coat has dried for 16-24 hours, you can move on to the following stage. After the first layer of paint has been put in, you may discover additional cracks and holes.

In rare cases, the first coat may also contain dust and other contaminants. Line markings might be apparent if you used a squeegee to apply the first layer.

These sections will need to be sanded to remove any imperfections that may be noticeable after the floor is finished. After that, pick up any remaining debris with a vacuum cleaner. The epoxy thinner can often be used to remove any leftover micro-dust.

Start the second layer only after all new cracks or holes have been sealed and filled. Wait an additional day for the filling to dry before re-coating is required.

Final Coat

The final layer should be the most straightforward part of floor paint for the basement if you follow the instructions in this article. Make sure the area is clean before you begin. You don’t want someone slipping and falling on the slick floor if you don’t close all the windows and doors.

Make use of a high-end roller. Some people use a squeegee to spread the product and then a roller to get a consistent surface. You can also walk on the wet coat and inspect any places with spiked shoes.

You may need a third coat to obtain the desired finish depending on the state of the original surface.
