Cratering, Foaming
Peeling
Cracking, Flaking
Blistering
Poor Hiding
Sagging, Drooping
Wrinkling
  • Possible Causes

    - Shaking a partially filled can

    - Using low quality or old latex paint

    - Rapid application

    - Applying over porous surfaces

    - Use of improper thinning solvent

  • Solutions

    - Leave can to sit for a while after shaking

    - Avoid paints over 2 years old

    - Apply sealer or primer over porous surfaces

    -Avoid excessive rolling or brushing

    - Sand properly before repainting

  • Possible Causes

    - Moisture seepage from leaks or exterior walls

    - Inadequate surface preparation

    - Applying oil-based paint on wet surface

  • Solutions

    - Eliminate cause of moisture

    - Scrape, sand and prime surface

    - Recoat

  • Possible Causes

    - Inadequate adhesion and flexibility

    - Over-thinning or overspreading

    - Inadequate surface preparation

  • Solutions

    - Scrape and sand well

    - If cratering occurs in multiple layers use a filler

    - Prime and recoat

  • Possible Causes

    - Improper wall adhesion due to surface contamination

    - Alkyd application over wet surface

    - Exposure to humidity or moisture

  • Solutions

    - Scrape and sand well

    - Clean surface properly suing household bleach and warm water (do not use detergents or ammoniate solutions)

    - Allow surface to dry 48hrs

    - Surface temperature should be >10⁰C and maximum 50% RH

  • Possible Causes

    - Use of low quality paint or tools

    - Use of light color paints over darker colors

    - High-speed application

  • Solutions

    - Use top quality paints and tools

    - If substrate is dark, prime first

    - Follow recommended application speed

  • Possible Causes

    - Excess paint, heavy thick coat

    - Over-thinning

    - Spray gun is too close to surface

    - Humid or cold condition during application

  • Solutions

    - Don’t let roller or brush hold too much paint

    - Do not thin unless it’s needed

    - Surface temperature should be >10⁰C and maximum 50% RH

    - If painting on new concrete, allow to cure for 30 days before priming

  • Possible Causes

    - Thick coat of paint

    - Painting under extremely hot or damp conditions

    - Applying on top of insufficiently dried primer

    - Improper surface preparation

  • Solutions

    - Scrape or sand to remove

    - Allow primer to dry completely

    - Repaint
