Applying a base coat is one of the first steps when beginning a plastering project. The basecoat provides an abrasive and thermal resistant layer that sits under the plaster and allows for insulation particularly when aggregate is not available. For walls and surfaces that are exposed to high traffic and changes in temperatures, the base coat will provide a sturdier surface, allowing your plaster projects to long term lasting power. Structo-Lite is one of the most trusted base layer products on the market and comes in several different lines for you to get the perfect product for your project. If you are unsure of what the best choice would be, make sure to consult with the friendly and knowledgeable staff at Bernardi Building Supply who will give you all the necessary information you need to make informed decisions.

Finishing Lime

Finishing Lime is a product that is constructed from double-hydrated dolomitic limestone and is used with gauging plasters and Keenes cement to provide a smooth troweling, highly workable plastering surface. Finishing Lime will move and stretch with the inevitable shrinkage that occurs with these types of masonry products. This product comes in several different ingredient mixtures and the staff at Bernardi Building Supply can help you pick the right combination for your plastering project.

Ceiling Texture Spray in Toronto

Textured ceiling application can be timely and be challenging without the correct tools and products. Ceiling texture spray allows you to apply your texture and be assured that any mistakes or issues will be covered up and smoothed over. These products can also be used to implement the touch to your entire ceiling. Ceiling texture spray comes in a variety of styles and textures depending on your preference and project. The staff at BBS is always there to help you find the perfect product for your ceiling surface projects. If you run into an issue during the process, you can always call us, and we will assist in the best way we can.

Veneer Board and Plaster

Veneer board and plaster is a method used to surface your interior walls. You apply a thin layer of plaster of a gypsum board base that is similar to drywall. Veneer boarding and plastering protects the gypsum board from softening when you implement the regular plaster to the wall. This product can easily be achieved in two coats and can save you a lot of time and money. This method is especially useful when you are taking on renovations of an older building that may not have the best insulation installed. BBS is committed to giving you the knowledge and quality product for all of your veneer board and plaster needs.

Magnesia Board

Magnesia Board or MgO board is a non-insulating product used for many different applications. Magnesia board can be used in wall and ceiling linings, fascias, soffits, tile backing, and underlayment. This product is especially useful in projects that require fire resistant products, noise cancellation, or mold and mildew control. Magnesia board is factory-made but is considered to be an all-natural product. BBS provides quality choices from some of the best suppliers in the world.
