Paint Problem Solving

With the proper insight and expertise, every painting problem is correctable.

	Blistering Blistering is caused when water or solvent vapours accumulate and expand below the paint surface.

	Lap Marks Lap marks occur when wet and dry layers overlap during application of paint or stain.

	Mildew Mildew forms most often on areas that tend to be damp, and receive little or no direct sunlight.

	Peeling from Asbestos Shingles After years of wear, asbestos cement siding can develop a surface layer of fine dust similar to chalk, causing the paint to peel.

	Peeling from Concrete Floors Concrete floors present numerous potential adhesion problems for coatings.

	Picture Framing on Drywall Hatbanding results in a heavy, textured paint application caused by the improper use tools or improper drying time.

	Peeling from Hardboard Siding Hardboard siding peeling generally originates at butt joints and drip edges.

	Peeling from Masonry and Brick Peeling is caused by efflorescence, the crystallization of residual salts in mortar, brick, building block or concrete.

	Peeling from Mill-Glazed Western Red Cedar or Redwood Siding Water-soluble resins rising to the surface create a varnish-like glaze that, in turn, will cause peeling.

	Peeling from Plaster Walls Paint peeling from plaster results from surface alkali, moisture, or even an excessive paint build up.

	Poor Galvanized Metal Adhesion Poor adhesion, often caused by improper surface preparation, results in peeling and blistering.

	Poor Hiding of Colours Excessive spreading or thinning, an uneven application—even a radical colour change—can cause poor hiding.

	Surfactant Leaching Leached surfactant appears as a brown or amber syrup-like deposit or in a white crystalline form.

	Tannin Staining Stains from red cedar, cypress and redwood result from a combination of moisture and insufficient sealing.

	Uneven Gloss Uneven gloss results from an unsealed porous surface, uneven applications, or insufficient drying time between coats.

	Wax Bleeding on Hardboard Siding Wax bleed causes discolouration on painted hardboard siding, changing its appearance and causing it to retain more dirt.
