What You Need
- A variable speed concrete polisher, water fed with a speed setting, hand-held.
- A squeegee.
- Diamond grinding pads. Coarser pads are essential in exposing aggregates and removing blemishes.
- Earplugs, googles, and a mask if you do dry-sanding.
First, begin by cleaning your countertop with water, then after that run the squeegee on top of it closely to get rid of any particulates sitting on the surface or grit. Doing this will cause you to gouge as you sand it.
Fill in the holes
After you prepare the countertop, be sure to clean all holes and flaws using a patching slurry before you polish it. Patching slurries comes in different colors to contrast or match against the countertop.
Rub the Surface
Immediately all the holes on the countertop are sealed, polish it using the coarsest pad that you have. Ensure you cover the whole surface for a smoother and even finish. Maintain the polisher level then make sure that it’s receiving a constant water flow.
Polish the Countertop Surface Using a Finer Pad
Move a step further, then polish the surface once again. Be sure to repeat this process with all pads that you have.
While changing pads, it’s essential to wipe the surface to get rid of debris and dust. Doing this gives you a clearer view of the working area and lowers the chances of imperfections.
Also, there isn’t a fast and hard rule for how long you need to use each pad or how much you need to polish the surface. Here, use your judgment
If there are places, the grinder can’t access, use your hand to sand the concrete.
Give It Time to Dry
Immediately the surface is fully dry and has attained the right finish that you want, allow it dry before you use any sealant to seal and protect your hard work.
Apply the Countertop Surface Using a Sealant
Finally, apply a concrete sealant on top of the sanded concrete. Doing this will help in protecting the surface from wear and tear or stains.
How to Sand Concrete Walls
Most concrete walls are a blank canvas. They habitually possess an industrial and cold feel. But if this design style isn’t what you desire your walls to feel like, then the solution is polishing them to get a high shine.
Immediately the walls are polished and sanded; be sure to coat them with a clear sealer, paint, or stain them to integrate your décor. Here is the step by step guide to do the task:
- Begin by washing the walls using water and dishwashing soap. Get rid of the soap residue through rinsing the walls using clean water and a sponge. Let it dry overnight.
- After that, attach a diamond pad on a hand-held grinder. Using a diamond pad is the only way to bear positive results as its strong enough to cut across the top layer of the concrete.
- Then press hard the grinder on the wall then apply gentle pressure. Shift the grinder back and forth and up and down all over the wall. After some time, the concrete will start developing a slight luster. For paint, ensure you’ll be required only to remove a little part of the upper concrete layer.
- Keep on sanding until you arrive at the desired shine you need.
- Finally, wipe the wall using a damp towel to clean away the sanding dust. Then prepare your wall and make it ready for stain, paint, or sealer.
