That concrete sealers lengthen the lifespans of concrete surfaces is certainly not in doubt.
Why is it important to seal your concrete garage floor?
Concrete that is not sealed tends to breakdown much faster than with concrete sealer. There is a lot types of concrete, however most break down if there is not something giving at a layer of protection.
Even decorative concrete is highly recommended as it preserves it shape and details for much longer.
Epoxy material serve protection against the surfaces of floors from all kinds of possible damages, staining, acts as a water repellent, and corrosion. It is because of this that you want to know how to apply it on concrete. And it works in garage floors, warehouses floors and basement floors too, especially in heavy traffic areas.
Most importantly, it could save you a lot money on concrete crack repair in the future. Epoxy is the best sealer work with and will do the job. The goal is to have fully sealer epoxy floor.
If you want to seal your own concrete, you should use a penetrating or a topical acrylic concrete sealer. As epoxy coating and polyaspartic sealers are more complicated to self perform.
Is it better to roll or spray concrete sealer?
It is preferable to sealing concrete with rolls because it applies a larger sealing material to the concrete surface. While is spraying is much faster and less labor intensive, it results a thin layer of coating which means you will have to apply multiple times.
Apply Sealer on Concrete Instructions
You have three main options to apply the sealer on concrete. We are going to look into these three main ways and explain them here below:
Apply Sealer Concrete with a Roller
1. Pour the sealer on a pan
Start off by pouring the sealer on a pan. Place the pan on a surface that is flat. Place the roller cover on the handle of the roller and then get rid of any wrapping. For the best outcomes, you are advised to invest in high-end covers.
2. Wet the roller
Prepare the roller for the subsequent sealing actions. Do this, dip the roller in some water. Shake the brush thoroughly to get rid of any water from its inner tube. Move on to blot and roll the cover using a rag or drop cloth.
3. Roll in the sealer
Now roll the roller inside the sealer until it is completely covered all round. You will require to do this typically around 5-6 times to effectively cover the entire roller with the sealer. In case there is excess sealer on the roller, roll it against the tray ridges or paint screens to remove excess paint drips.
4. Roll on the concrete floor
This is the core of the entire exercise. Roll the sealer on the concrete floor. Start at about some inches from the bottom of the wall. As you do so, apply some stroke of the paint upwards and using even pressure.
5. Continue Rolling
Keep on rolling the sealer on the concrete floor in a ‘W’ or zig-zag pattern until all the sealer on the roller has become extremely thin. Spread out the sealer in such a manner as to enable it to be evenly spread out on the surface as possible.
7. Finish the sealing
Repeat the three previous procedures a couple of times to see to it that the entire concrete floor is fully covered. If necessary, you might have to add a second layer of coating on top of the first one by use of the same techniques.
Use a Sprayer to Apply Sealer
As explained above, you may also use a spray sealer to do the job of applying the seals on the concrete. The procedures to follow vary slightly due to the differences in the structures of the items used. Below are the procedures to follow:
1. Sweep the concrete surface
First and foremost, sweep the concrete surface which you intend to apply the sealer. This is necessary to get rid of any debris and dirt which might impede the outcomes. It also allows for smoother applications in the process.
2. Mop the floor
After sweeping the concrete surface, mop the floor using some clean water and floor cleaner. If possible, clear out any remaining debris and water using the shop vacuum. Leave it unattended for around 24 hours to dry.
3. Fill any cracks or pitting
Before applying the sealer, be sure to fill any existing cracks or pitting. Use the concrete repair sealant to do this. Apply it to the affected portions of the floor and smoothly over using some putty knife. To be on the safe side, read and follow the manufacturer’s manual.
4. Spray the sealant
Now spray the sealant on the concrete surface. Simply open the nozzle and then release the stream of sealant on the floor. Take care not to stuff in one portion of the floor with too much sealant at the expense of the other segments.
5. Lay some final touches
After you have sprayed the entire surface, you now have to lay some final touches. Apply some two thin coats to see to it that you obtain some uniform finish. Leave the surface to around two hours to let it dry and harden completely before resuming use.

Tips for Applying Sealer
We now want to examine some of the tips to adhere to while applying the sealer. These will go a long way to ensure you some great experience and outstanding outcomes.
1. Follow the manufacturer’s manual
Each sealant is unique due to the different manufacturers who produce them. It is in your best interest to read and adhere fully to your manufacturer’s directions. That way, you will avoid the common mistakes which are generally bound to arise.
Follow carefully if you have an aggregate concrete floor as it is applied a bit differently to other less rough concrete.
2. Be mindful of the air temperature before applying the concrete sealant
It is necessary that you be mindful of the air temperature prior to your application of the sealant. The ideal temperature range for sealing is around 50°F-80°F. On the same note, you should also desist from applying the sealant if rain is anticipated with a duration of 24 hours or if the humidity levels exceed 80%.
3. Never allow sealers to puddle on the concrete
While applying the sealants, never allow them to form puddles on the concrete. To guarantee this, apply only minute amounts of the sealer at a time. Give it a break to allow for its absorption into the concrete before overlaying yet another layer.
4. Prepare the concrete surface accordingly
Prior to the application of the sealant, be sure to prepare the concrete surface accordingly. These include cleaning the floor thoroughly and setting the right surface profile. After the preparation, let it dry completely before going ahead to apply the sealant.
5. Use the right kind of roller
Needless to say, you have to use the right kind of roller for the job. The lint-free roller is, by all means, the most suited for the job. Using cheap rollers save money but do not yield the reliability required for great outcomes.
Well, you now have what it takes to do a good job. As you may see from the foregoing explanations, this is a job that anyone can do. However, it requires a great deal of focus, patience, and attention on your part. To beat the system, you have to do a lot of practice and preparations.
The end goal is to have a nice polished garage floor, or driveway that will last you a lot of years.
What type of roller do you use to seal concrete?
To apply concrete sealer with a 3/4-inch to 1 inch nap paint roller. It’s specifically made to handle rough surfaces such as plaster and concrete. A
3/4-inch is for semi-rough surfaces concrete surfaces while the 1 inch for
rough surfaces like heavy concrete textured ceiling.
