Interior Exterior
BLISTERING
Description

The appearance of bubbling, which is often the result of trapped moisture and/or a lack of adhesion

POSSIBLE CAUSES
  • Trapped moisture or solvent underneath the coating.
  • The use of a solvent-based coating over a damp substrate.
  • Painting in a damp or high-humidity area.
  • Painting over a contaminated surface or other bond breaker.
RECOMMENDATIONS
  • See Lead Information for warnings.
  • Allow sufficient time for blisters to go down. Determine the source of the moisture, and eliminate the problem by installing proper ventilation and caulking all openings.
  • If blisters do not go down, remove them by scraping and sanding.
  • Apply one coat of Pratt & Lambert Multi-Purpose Waterborne Primer.
  • Apply 1-2 coats of Accolade® Interior Paint + Primer.
BLOCKING
Description

The sticking together of two painted surfaces. Occurs more often with latex paints on trim work such as windows and doors.

POSSIBLE CAUSES
  • Not allowing proper dry time before closing windows or doors.
  • Use of a low-quality latex semi-gloss or gloss paint.
  • Hot, humid or damp conditions.
  • Lack of good ventilation.
RECOMMENDATIONS
  • See Lead Information for warnings.
  • Read and follow proper recoat and drying times.
  • Do not paint in hot, humid or damp conditions.
  • Use a top quality semi-gloss acrylic product such as Accolade® Interior Acrylic Semi-Gloss Paint + Primer or RedSeal™ Interior Oil Satin Enamel. 100% Acrylic paints have better early block resistance than vinyl latex paints, but alkyds do develop superior block resistance over time.
BURNISHING
Description

Shiny spots on a paint film caused by objects rubbing against the surface.

POSSIBLE CAUSES
  • Use of a low-grade paint with a poor scrub rating.
  • Inappropriate cleaning methods, such as using an abrasive cloth or cleaner.
  • Objects frequently rubbing against the walls.
  • Use of flat paint in highly trafficked areas.
RECOMMENDATIONS
  • ee Lead Information for warnings.
  • For best results, clean painted surfaces with a soft cloth or sponge and use non-abrasive cleaners.
  • Apply 1-2 coats of Accolade® Interior Paint + Primer. Accolade® was specifically formulated to offer the best burnish resistance. It provides exceptional durability and easier cleaning capability.
CRACKING/FLAKING
Description

Initially may appear as a hairline crack but often results in complete flaking of paint chips.

POSSIBLE CAUSES
  • Use of a poor-quality paint that lacks proper adhesion and flexibility.
  • The failure to apply coating at recommended spread rates.
  • Inadequate surface preparation.
  • Aging oil-based paint that has become too brittle.
RECOMMENDATIONS
  • See Lead Information for warnings.
  • Remove as much loose paint as possible by scraping and sanding.
  • Apply one coat of Pratt & Lambert® Multi-Purpose Waterborne Primer.
  • Apply 1-2 coats of Accolade® Interior Paint + Primer.
FOAMING/CRATERING
Description

The formation of bubbles that may break and result in craters during the application and drying process.

POSSIBLE CAUSES
  • Over application of product (rolling too rapidly).
  • The use of a low-grade or old paint.
  • Over shaking the paint prior to painting.
  • Applicator did not use the recommended roller cover nap length.
  • Finish coat was applied over an unprimed, porous surface.
RECOMMENDATIONS
  • See Lead Information for warnings.
  • Problem areas should be sanded smooth prior to repainting.
  • Apply one coat of Pratt & Lambert® Multi-Purpose Waterborne Primer to seal any porous surfaces.
  • Avoid excessive rolling or brushing during application.
  • Follow recommended application procedures and use appropriate roller cover nap sizes.
  • Apply 1-2 coats of Accolade® Interior Paint + Primer. Accolade® was specifcally formulated to provide superior flow/leveling, which lessens the potential of bubbling occurring.
LAPPING
Description

Appearance of a denser color or increased gloss where wet and dry layers overlap during paint application.

POSSIBLE CAUSES
  • Failure to maintain a “wet edge” during application.
  • The use of low-grade, low-solids paint.
  • Applying finish coat to an unprimed, porous surface.
RECOMMENDATIONS
  • See Lead Information for warnings.
  • Always maintain a wet edge when painting by starting in an unpainted area and then paint from “wet to dry”.
  • If the substrate is very porous, apply one coat of Pratt & Lambert® Multi-Purpose Waterborne Primer. This will help prevent the finish coat from drying too quickly and reducing wet edge time.
  • Apply 1-2 coats of Accolade® Paint + Primer. The high solids content of this premium finish will make lap marks less likely.
MILDEW
Description

Black, gray or brown spots often found on the surface of paint or other surfaces in damp or shaded areas.

POSSIBLE CAUSES
  • Tends to grow in areas that are damp and receive little or no direct sunlight (basements).
  • Use of a low-quality interior-grade paint in high moisture areas, such as bathrooms or kitchens.
  • Use of low-quality interior-grade paint in high moisture areas, such as bathrooms or kitchens.
  • Use of an alkyd or oil-base coating, which tends to be more susceptible to mildew growth.
  • Failure to use the appropriate primer before painting.
  • Painting over existing mildew.
RECOMMENDATIONS
  • See Lead Information for warnings.
  • Mildew must be completely removed by scrubbing with a solution of 1 part bleach to 3 parts water, or with an appropriate mildew cleaner (be sure to protect skin and eyes).
  • Rinse surface throughly and allow to dry.
  • Apply one coat of Pratt & Lambert® Multi-Purpose Waterborne Primer.
  • Finish with 1-2 coats of Accolade® Interior Paint + Primer.
MUD CRACKING
Description

Heavy sags with irregular cracks that resemble dried mud in the paint film.

POSSIBLE CAUSES
  • The main reason mud cracking occurs is because the paint is applied too heavily, or more than the recommended wet film thickness. The most common cause is the applicator trying to apply one heavy coat of paint instead of two.
  • Paint buildup in certain areas such as corners.
RECOMMENDATIONS
  • See Lead Information for warnings.
  • Coating must be scraped and sanded smooth.
  • Apply one coat of Pratt & Lambert® Multi-Purpose Waterborne Primer.
  • Finish with 1-2 coats of Accolade® Interior Paint + Primer. Accolade® Finishes have a high solid content which increases hide and minimizes the tendency to apply the coating too heavily.
PICTURE FRAMING
Description

The visual effect on a wall surface that resembles the frame of a picture. This often occurs when a wall is painted with a roller, but is brushed at the corners. The brushed areas generally appear darker creating a “frame”.

POSSIBLE CAUSES
  • The applicator uses paint from one can to roll the walls, and paint from another can to brush them. There may be a slight color variance between the different batches of paint.
  • The brushed areas may appear darker than the rolled areas.
  • A hide or coverage issue due to the different spread rates of brushing and rolling.
  • Applicator cut in too much in at one time and did not maintain a wet edge. Best results are achieved by cutting in one wall at a time and rolling before those areas have dried.
RECOMMENDATIONS
  • See Lead Information for warnings.
  • Use the same material (batch) to brush and roll the walls.
  • Do not cut in the entire room before rolling. Always maintain a “wet edge” by working in small sections.
  • Stir your paint occasionally to avoid any tint settling.
  • Be sure the correct colorant-base combinations are used.
  • Use high-quality products with excellent application characteristics such as Accolade® Interior Paint + Primer.
POOR FLOW/LEVELING
Description

Failure of paint to form a smooth film without brush marks or roller stipple appearing.

POSSIBLE CAUSES
  • Use of low-grade interior paint.
  • Applying paint before underlying coat has dried.
  • Paint applied too heavily, or more than the recommended wet film thickness.
  • The use of a poor quality or the wrong type of brush or roller cover.
RECOMMENDATIONS
  • See Lead Information for warnings.
  • Sand walls smooth to eliminate any stipple or texture.
  • Use the manufacturer’s recommended roller cover and brush type.
  • Use high quality products with excellent application characteristics such as Accolade® Interior Paint + Primer. Accolade® is formulated to provide superior flow and leveling, which results in a smooth, elegant finish.
POOR HIDING
Description

Paint lacking the ability to hide or obscure a surface when it has been uniformly applied.

POSSIBLE CAUSES
  • The use of a low-grade paint or lighter color than the substrate.
  • The use of a poor-quality or the wrong type of brush or roller cover.
  • Paint was spread too thin and not applied at recommended wet film thickness.
  • Paint was over reduced before application.
  • Color containing organic colorants, like bright yellows or reds, was used and naturally does not hide as well as muted colors.
RECOMMENDATIONS
  • See Lead Information for warnings.
  • Always use high-quality, recommended applicators.
  • If the substrate is significantly darker, prime with Pratt & Lambert® Multi-Purpose Waterborne Primer prior to applying the finish coat.
  • If a deep bright color is selected, prime with Interior Latex Deeptone Primer and have it tinted to the recommended grey shade.
  • Finish with 1-2 coats of Accolade® Interior Paint + Primer. Accolade® Finishes have a high solid content, which increases their hiding ability.
POOR SCRUB RESISTANCE
Description

Being able to remove some of the paint film when properly scrubbing with a brush, sponge or cloth.

POSSIBLE CAUSES
  • Use of a low-grade paint.
  • Use of an abrasive cloth, or over-scrubbing the surface.
  • Use of an abrasive cleaner.
  • Not allowing proper cure time before scrubbing.
  • Paint was spread too thin and not applied at recommended wet film thickness.
RECOMMENDATIONS
  • See Lead Information for warnings.
  • Areas that need frequent cleaning require a high quality paint, such as Accolade® Interior Paint + Primer. High traffic areas may require the satin or semi-gloss sheen to provide better scrub resistance.
  • Allow paint to fully cure (generally 28 days with acrylics) before attempting to scrub the surface.
  • For best results, always use non-abrasive material and mild detergents when cleaning the surface.
POOR SHEEN UNIFORMITY
Description

An uneven gloss or sheen on a painted surface (may also be referred to as “flashing.”)

POSSIBLE CAUSES
  • Paint was not applied at an even spread rate.
  • Painting over an unprimed surface with various degrees of porosity.
  • Poor application methods resulting in lapping (see Lapping).
RECOMMENDATIONS
  • See Lead Information for warnings.
  • New substrates should be primed/sealed with Pratt & Lambert® Multi-Purpose Waterborne Primer to ensure a uniform surface.
  • Finish with 1-2 coats of Accolade® Interior Paint + Primer.
  • Always maintain a wet edge when painting and apply the paint from “wet to dry”.
POOR STAIN RESISTANCE
Description

The failure of the paint to resist absorption of dirt and stains.

POSSIBLE CAUSES
  • The use of low-grade paint that is porous in nature.
  • Applying paint to a substrate that has not been properly prepared or primed.
  • Stain absorbs into the paint film prior to its full cure.
RECOMMENDATIONS
  • See Lead Information for warnings.
  • Properly prepare the surface, assuring it is clean, dry and in sound condition.
  • New substrates should be primed/sealed with Pratt & Lambert® Multi-Purpose Waterborne Primer to ensure a uniform surface. Priming new surfaces provides maximum film thickness of the finish coat, thus providing very good stain resistance and removability.
  • Finish with 1-2 coats of Accolade® Interior Paint + Primer. Accolade® Finishes contain more binder, which helps prevent stains from absorbing into the surface.
POOR TOUCH UP
Description

A noticeable difference in appearance with the original finish and the touched-up areas.

POSSIBLE CAUSES
  • A different batch of product was used when touching up.
  • A different applicator was used when touching up (for instance - original was rolled, touch-ups were brushed, thus a different texture was created).
  • Touch-ups were performed in different temperatures than the original paint job.
  • Poor touch-up techniques were used.
RECOMMENDATIONS
  • See Lead Information for warnings.
  • Before touching-up, try to remove the marks or contaminants with a soft sponge and liquid detergent.
  • Always use the original material (batch), if possible, when touching-up.
  • Try to use an applicator similar to the one used during the original paint job.
  • Follow proper touch-up techniques such as “feathering-in” the edges.
SAGGING
Description

The downward movement of the paint film immediately after application, resulting in an uneven appearance.

POSSIBLE CAUSES
  • Paint applied too heavily, or oat more than the recommended wet film thickness.
  • Product applied during, or prior to, excessive humidity or cool conditions.
  • Paint was over-reduced prior to application.
  • Poor application techniques.
  • Applying finish coat to a slick, glossy surface.
RECOMMENDATIONS
  • See Lead Information for warnings.
  • If the paint has not dried, try to brush out or re-roll the problem areas.
  • If the paint has dried, sand smooth before reapplying a new finish coat.
  • Assure humidity levels and temperature are ideal for painting.
  • Apply 1-2 coats of Accolade® Interior Paint + Primer at their recommended spread rates.
