It is unpleasant when there is a noticeable gap between a countertop and a backsplash, and it may also enable water to soak through. If the gap is too large to seal with silicone, the issue may be solved in an appealing manner by using thin trim moulding. Moldings like as quarter-round and cove are designed to fit into a corner with a 90-degree angle, such as the one that exists between a countertop and a backsplash. The quarter-round profile has an outwardly rounded profile and is often used at the bottom of baseboards. The crown moulding detail known as a cove curls inward and serves as an accent. Wood that can be stained or painted, as well as water-resistant plastic, are also available for either option.
1. Measure the Countertop
Take a measurement of how long the countertop is.
2. Measure the Trim Molding
Mark with a pencil the length of the countertop using a stick of quarter-round or cove trim moulding made of wood or plastic that has been measured to that length.
3. Cut the Trim Molding
Using either a hand saw or an electric mitre saw with the angle set to zero degrees, cut the moulding at the pencil mark.
4. Sand the Ends of the Molding
Sand both ends of the moulding with a light layer of sandpaper so that any roughness on both ends is removed and the front side of the cut edges are rounded off.
5. Clean the Surfaces
Rub some rubbing alcohol on a cloth, and then use it to clean the rear edge of the countertop as well as the bottom edge of the backsplash.
6. Prepare the Epoxy
Remove the caps from both tubes of the 2-part epoxy adhesive dispenser kit and, if required, trim the tips of the tubes off using a utility knife. Once the tubes are open, the epoxy glue may be used. Maintain pressure on the dispenser’s trigger until the epoxy reaches the very end of each of the nozzles on the dispenser.
7. Flip the Molding
You should be looking at the underside of the moulding when you do this.
8. Apply the Epoxy
Put pressure on both tubes of epoxy and squeeze a line of the substance simultaneously over the bottom rear side of the moulding. The section of the moulding that will come into contact with the countertop is the bottom rear side of the moulding. It is important to avoid getting epoxy on the part of the upper back that will be touching the backsplash.
9. Press the Molding Into the Gap Between Counter and Backsplash
In order to fill the corner gap between the counter and the backsplash, you will need to flip the moulding over and push it into place. Epoxy has a short curing period, so you will need to align the ends of the moulding with the ends of the countertop as soon as possible. Hold the moulding in place while the glue sets, and while doing so, rub your fingers back and forth along the moulding. Continue doing this for the amount of time that the maker of the epoxy suggests for a strong connection.
10. Seal the Edge of the Molding
A slender bead of clear silicone should be used to seal the top edge of the moulding where it meets the backsplash. If you so want, run an additional bead of silicone around the bottom edge of the moulding, where it makes contact with the countertop.
Some Special Considerations
Cove moulding, quarter-round moulding, and trim moulding made of wood or plastic
Sawing using a handsaw or a mitre saw
Sandpaper, ultra-fine grain
Alcohol for the purpose of rubbing!!-!! Rag
