Frequently Asked Questions
When is a scratch coat required?
A scratch coat is usually only required for exterior projects; interior jobs do not require a scratch coat.
How many bags of mortar or parging mix will I need to complete my project?
1 bag of TradeMix Mortar Mix (Type S or Type N) or 1 bag of Parging mix will cover approximately 10 square feet, depending on the thickness of the application.

What is efflorescence?
Efflorescence is a crystalline deposit of water-soluble salts on the surface of masonry. Although efflorescence is unsightly and a nuisance to remove, it is not harmful to masonry nor does it affect its structural integrity. For efflorescence to occur, a number of conditions are necessary; there must be a source of water into the masonry, there must be soluble salts within the masonry, and there must be a path for the water to get to the surface of the masonry and evaporate. Efflorescence may only occur occasionally (ie. after a wet spring snowfall) or it may be ongoing because of a bad flashing or deteriorated caulking which allows moisture into your masonry wall. Efflorescence is generally associated with wet weather but may also appear temporarily early life of a new building as the construction moisture in the mortar and materials evaporate. The source of the soluble salts may be from either the cement and/ or lime in the mortar, adjacent materials or occasionally the brick.
Can I prevent efflorescence?
Efflorescence can be avoided, or at least minimized, during construction by limiting the amount of moisture which can enter into the brick and/or masonry. Excess moisture in the brickwork increases the risk of efflorescence. During inclement weather, the brick cubes should be stored on skids, and covered with board. This will prevent the brick from getting saturated before installation. During construction, the top of all masonry walls and veneer must be covered at work stoppages, especially during inclement weather. The cover should extend a minimum of 2 feet (600mm) down both sides and should be held securely in place. Also avoid storm water runoff, from roofs and slabs above, onto the masonry. This precaution of covering masonry also applies to openings left in masonry during construction. Typical examples include: The brickwork below window sills, prior to the installation of the windows and sills Tops of parapet walls, prior to the installation of a cap The horizontal movement joint below shelf angles, prior to caulking These openings are generally addressed by another trade, but due to trade scheduling are sometimes left open for a period of time. These openings are ready entry points for water and can result in extensive efflorescence. In these cases, the top of the exposed brickwork should be suitably covered, as described above.
How can I get rid of efflorescence?
First try washing the stone or brick with hot soapy water or a vinegar solution. If that does not work please consult Fraser Powell at Cast Supply and he will advise which kinds of chemicals are available to you.

Actual Size, also referred to as Specified Size, is the real dimension of each brick. Nominal size is the actual size plus the width of the mortar joint. Most bricks are manufactured so that the nominal sizes fit into a grid of 4", which coincides with the modules of other building materials such as doors, windows, and wood components.
How do I properly calculate the materials I will require for my project?
First Measure the square footage of the total area that is to be covered by stone. If you are using corners on your project, plan for each linear foot of corner pieces to cover 3/4 square foot of the area. For Example: If you have 100 square foot wall with an 8 foot corner, the corner pieces would cover 6 square feet of wall. Subtracting 6 from 100, you would need 94 square feet of flat stone and 8 linear feet of corners.
What is manufactured stone made of?
Our Boulder Creek Stone is a precast concrete product composed of Portland cement, aggregate, water, admixtures and coloring.
What is the difference between Boulder Creek Manufactured stone from your competitors stone?
Boulder Creek has a compressive strength of 5500 psi versus 1800 psi on cultured stone. The overall end result is you have a stronger product less susceptible to damage from the environment. Also, Boulder Creek exceeds all areas required by the building codes in both US and Canadian markets. If you look at the properties of Boulder Creek versus Cultured Stone and Eldorado Stone (our 2 biggest competitors) certain areas stand out.
How can I fix damaged stone?
Small nicks and chips can be repaired using a color touch-up kit. Please contact us for your color touch-up kit.
