Here’s what you’ll need for this guide:
- Measuring tape
- Caulking gun
- Filler (silicone or acrylic)
- Sandpaper
- Putty knife
- Paint (for the wall)
- Cloth

Instructions For Filling Gaps
Step 1: Clean the area
Before you fill the gaps, it’s important to clean and remove any dirt, debris, or dust that could cause an issue with the filling.
Use soapy water and a cloth or sponge to clean the surface. If you can, fire up the vacuum machine and use a thin nozzle to deep-clean between the gaps.
Once the area has had some time to dry, you can move on to the next step.
Step 2: Sand
Using the sandpaper, gently sand between the surfaces where the gap will be filled.
Avoid sanding over the countertop because that can wear down the top coat on the surface.
By sanding down and smoothing out this surface, you will ensure superior adhesion or application for the caulk or filler.
Step 3: Choose a filler
You have a choice between silicone or acrylic latex caulk to fill gaps between countertops and walls.
They’re both durable, easy to apply, and moisture-resistant.
Silicone caulk offers great water resistance, whereas acrylic latex caulk offers more customization and flexibility with color.
Step 4: Apply the filler
Once you’ve selected the type of filler or caulk you’re going to use to fill the gaps, insert it into the gun and begin the application process. It is always advisable to start from one end of the gap or countertop.
Apply an even layer of caulk along the gap until you reach the other end. When you’re done, grab the cloth and wet it, or use a tool that is designed for filling gaps and allows you to remove excess caulk.
From one end to the other, smooth out and remove excess caulk until the gap appears smoothly filled.
You need to do this before it dries. In some instances, you can use soapy water to spray the caulk before smoothing it out and flattening the edges.
Step 5: Allow it to dry
Regardless of what filler or caulk you use to fill the gap, it will need time to cure and fully dry.
You’ll find this information on the product or in the box, which stipulates instructions for proper use.
Generally, follow the manufacturer’s instructions for the best results, but to be on the safe side, give it between 24 and 48 hours.
When the caulk or filler has completely cured, check the area for any bubbles, holes, or imperfections. If the edge or surface is too rough, consider sanding it down lightly with fine-grit sandpaper.
Thereafter, dust the area with a dry cloth and apply a coat of paint to blend the caulk with the wall, if need be.
Alternative Solutions For Gaps
If you’re unwilling to use the caulking approach, there’s always the possibility of using epoxy to fill the gap. The process is very similar except that the application may require you to be more hands-on, unlike with the caulking gun.
Then, there’s the option to conceal the gap without actually filling it.
You could add trimmings to the wall that cover the gap while also adding a decorative border between the countertops and the wall.
In fact, a lot of homeowners tend to add a backsplash to the wall behind the countertops as an aesthetic feature that also protects the wall from splashes and spills caused by cooking and eating in the kitchen.
Final Thoughts
If you follow the instructions in this article or opt for one of the alternative solutions mentioned above, you should be able to successfully and professionally fill a gap between countertops and walls.
Once you do, it’s important to maintain the area by cleaning it regularly and gently.
Avoid using harsh chemicals or abrasive cleaning tools to preserve the finish and integrity of the filler used in the gap.
Aim to achieve a seamless and cohesive appearance between the countertop and wall after filling the gaps, and you’ll end up with a result that looks amazing.
