Parging

Parging is a way to apply a smooth surface to a masonry wall. It is used to apply a smooth surface to the exterior of a concrete foundation so that a waterproofing compound can be applied more easily.

Parging is also frequently used to cover up deteriorating masonry on the outsides of buildings or to provide a smooth surface for the application of new finishes on the inside and outside of a building.

Older Toronto parged walls begin to deteriorate. They show many cracks, and a part of the outer layer starts falling off. At this point, the old parging is fully removed and redone which gives your building or home a brand new look.

Parging in Toronto, sometimes but not very often, is used in new construction to artificially age a building. This is usually done in movies props etc.

The material used is mortar or Portland-cement based and is applied with a trowel, usually in several thin coats, directly over the masonry that it repairs or conceals. One should never put it over deteriorating bricks as the bricks will not hold the layers of mortar very well as the bricks will continue to deteriorate beneath. Always repair the wall then parge over the repaired wall.

Stucco can have a similar appearance or it may have a textured or decorative appearance.

Parging is commonly used at the bottom of a brick wall to protect the most vulnerable part of a building from water and snow. This is accomplished by applying a special type of cement to create a smooth flat surface.

Parging is also used on exterior house walls and even on chimney’s to give your house a very smooth and classic look. Parged walls can also be painted.
