With brick mold frames, you can construct any wall you want, including a kitchen countertop, an open plan bathroom, a garage wall, and more.
To make the project, you’ll need a frame that’s sturdy enough to withstand the force of the mold and the stresses it creates.
But to build a sturdy brick mold, you need a way to attach it to a wall.
Measure the width and height of the frame.
You can find these dimensions in a wall catalog or online.
The ideal width is about 7 feet (2 meters).
The ideal height is about 10 feet (3 meters).
To find your ideal width and/or height, measure the wall behind the molding and measure the distance between the mold’s edges.
If you’re working from the inside, make sure you have a good view of the interior of the wall, too.
If the wall is a flat surface like a countertop or door frame, the width of the ceiling will determine your height.
If it’s a slab or an open wall, the height will determine the width.
Determine the thickness of the walls you’ll use.
You need a minimum of 2.5 inches (7.8 centimeters) of solid, smooth concrete (which is the same kind of concrete used to build houses).
This can be determined by measuring the wall surface.
Measure around the edge of the top of the countertop.
For the countertops, use 1.5 to 2 inches (3 to 6 centimeters) thick concrete.
For other types of walls, such as doors, you should use a minimum 2 inches to 2.25 inches (5 to 7 centimeters).
The thicker the concrete, the more solid it will be.

Cut the frame into 1-foot (30 centimeters) pieces.
Make sure each piece is 1.25 to 1.50 inches (4 to 6.5 centimeters) in diameter.
For example, if you’re using a standard-size countertop and it’s 8 feet (24 meters) tall, you’d cut it into 8 1-inch (38.8 cm) pieces of 1.4 to 1 1/4-inch-diameter (4.6 to 5.5 mm) concrete.
Secure the pieces in place.
You’ll need to secure each piece in place before you can install it.
Secure each piece with screws or screwspulleys or screws that are 3/8-inch (.8-centimeter) or larger.
To attach the piece to the wall using screws, attach the frame to the top surface of the other wall, using the top edge of one of the screws as a guide.
For larger-sized molding, you may need to use a screw with a larger diameter, such a 2-inch [5.3-centimeters] diameter.
The piece should also be attached to the concrete in the same way as the other piece.
To secure the frame, mark the area where you want the mold to sit, then attach the top piece to a sturdy surface.
Secure all pieces of the framework in place by backing up the entire wall.
Then, remove the entire frame and attach it again to the next wall.
This will allow the mold piece to sit securely on top of any existing concrete, and the wall will stand.
Fill the mold.
To fill the mold, drill holes in the walls, adding about an inch (2 centimeters) to each side.
If possible, use concrete that is not too soft, but not so hard that it’ll break or deform.
You want to fill the entire space, so make sure the bottom of the holes are deep enough to support the concrete.
When you’re done, the mold should look like this.
You should be able to remove the mold after the wall has been installed, since the cement won’t dissolve completely.
You may need a molding bucket to fill it with cement.
To install the mold on a wall, drill two holes into the bottom edge of each piece of concrete.
Add about an 1- to 2-pound (2 to 5 kilograms) of cement to each hole.
To put the mold in place, mark a hole in the mold that’s the same size as the hole you drilled to attach the mold frame to a concrete surface.
Attach the mold using screws or the screwspole or screwdriver.
If necessary, fill the holes with cement, as necessary.
The mold will then be secure in place for a year or more.
