How Much Bricks or Stone Do I Need?
Follow these easy step to determine how much “Gypsum JOY” products you will need.
- Measure the width and the height of the area to be covered and convert to square footage; width x height = total square footage.
- Figure the square feet of any windows, doors, and openings and subtract this amount from the first figure. (total square footage – windows, doors, and openings).
- Allow for at least an extra 10% more bricks or stone for broken pieces, cutting, and trimming.
Plan your project
No matter the type of gypsum veneer you are working with, a big factor in a successful project is the planning and extensive measuring. Prior to the installation you should decide on the way you are going to work around window openings, outlets, and on the use of a grout line. Be aware of sight lines when cutting, drilling, trimming, and placing the stone. Try to place cut edges up when they are above eye level and down when they are below eye level. Also it is recommended to smooth out and prime the surface. Unpack multiple boxes of stone veneer, and arrange a laying pattern prior to starting the installation.
Do I need corner pieces?
No, no expensive corner pieces are needed. The way to form corners, or corners that are not at 90 degrees, is to miter cut stones on site. To miter cut a corner, select one stone and mark the point where the join should be. Cut the stone at the mark with no tilt (a 0 degree angle) on the saw. Then the two pieces need to be individually cut on a 45 degree miter to form a right angle. Once cut, check the stone to make sure it forms a perfect 90 degree corner. The color, the width and thickness of the stone pieces should match to form a continuous look that seems to “flow” around the corner. Never use 2 different panels to form a corner, as the color, texture and thickness will not match as desired.
For the installation of Gypsum stone-look a fine handsaw, and file or rasp is sufficient for cutting, trimming, and to make miter cuts.
Application of adhesive
Apply the tile adhesive on the wall and on the back of the brick or stone with a notched trowel. Ensure all depressions on the back of the panel are filled and that the edges of the panel are kept clean from mortar. Work small spaces at a time to prevent the adhesive to dry too quickly.
Placing the stone
By horizontally sliding and pushing it firmly, place the brick or stone on the wall. Use spacers for the desired joint. Leave the spacers in until the adhesive has completely dried (> 24 hours). When installing, ensure all mortar is removed from the edges of the panel prior to installing the adjacent pieces. This will ensure that all adjacent pieces are installed as tight as possible and thus eliminating unsightly gaps. Vertical joints should be randomly staggered to disguise the seams.
Grouting & Finishing Joints
After the adhesive has completely dried (> 24 hours), remove the spacers and apply the grout in the desired color. After the required drying time, smooth the grout line with a pointed trowel. Brush away dust and any grout or mortar residue. This brushing can also gives the joint its texture. If you want to do this make sure you do this before the grout has fully dried.
