This section highlights the problems that may occur when painting. We have categorized these problems in terms of area of occurrence, namely interior and exterior. We have identified the causes of these problems and provide cures that should rectify them.  \n• Blistering  \n• Blocking  \n• Burnishing  \n• Sealant Failures  \n• Cracking / Flaking  \n• Foaming / Cratering  \n• Lapping  \n• Mildew  \n• Mud Cracking  \n• Picture Framing  \n• Poor Flow/Levelling  \n• Poor Hiding  \n• Poor Print Resistance  \n• Poor Scrub Resistance  \n• Poor Sheen Uniformity  \n• Poor Stain Resistance  \n• Roller Marks / ”Stipple”  \n• Roller Spattering  \n• Sagging  \n• Surfactant Leaching  \n• Wrinkling  \n• Yellowing  \n• Alligatoring  \n• Blistering  \n• Chalking  \n• Chalk Run-Down  \n• Cracking / Flaking  \n• Dirt Pickup  \n• Efflorescence / Mottling  \n• Fading / Poor Colour Retention  \n• Frosting  \n• Lapping  \n• Nailhead Rusting  \n• Fungal / Algal Contamination  \n• Paint Incompatibility  \n• Peeling  \n• Poor Alkali Resistance  \n• Poor Galvanised Metal Adhesion  \n• Poor Gloss Retention  \n• Surfactant Leaching  \n• Tannin Staining  \n• Wax Bleed  \n• Wrinkling  \nAll images courtesy of the Dow Chemical Company.  \nCOMMON  \nPAINT  \nPROBLEMS  \nImportantly, we have also provided you with information on how to prevent these problems from occurring again.

If blisters do not go all the way down to the substrate:  \n• Remove blisters by scraping, and sanding, and repaint with a quality acrylic water-based interior paint  \nB. If blisters go down to the substrate:  \n• Remove the source of moisture, if possible  \n• Repair loose sealants: consider installing vents or exhaust fans  \n• Remove blisters as above, remembering to prime before applying the topcoat  \nBLOCKING  \nUndesirable sticking together of two painted surfaces when pressed together (e.g., A door sticking to the jamb) .  \nPOSSIBLE CAUSES  \n• N","cbCaidQxPzeXgkR2","https://ap.wps.com/l/cbCaidQxPzeXgkR2","pdf",4814125,"English","# Exterior\n## Common exterior painting problems\n# Interior\n## Blistering\n## Blocking\n## Burnishing\n## Sealant Failures","[{\"question\":\"What are the main types of common paint problems covered in the guide?\",\"answer\":\"The guide categorizes problems by area of occurrence, specifically interior and exterior, and lists potential defects such as blistering, cracking/flaking, wrinkling, mildew, and poor flow/levelling.\"},{\"question\":\"What causes blistering in interior paintwork?\",\"answer\":\"Blistering can result from applying solvent-based paint over a damp/wet surface, moisture seeping through exterior walls, or exposing dried water-based paint film to high humidity or moisture with inadequate surface preparation.\"},{\"question\":\"How should blocking be addressed?\",\"answer\":\"Blocking is addressed by allowing sufficient drying time before closing doors or windows and using top quality satin or gloss acrylic water-based paint.
