Apply Sealer Concrete with a Roller

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

Tips for Applying 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.

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
