Zinsser Peel Stop
Zinsser Peel Stop is a clear, flexible bridging sealer for surfaces where peeling, flaking, dusting or chalking is a problem. Use indoors or out to form a breathable membrane over questionable or faulty substrates. It tightly bonds to old paint and problem areas forming a sound surface for new paint. Its tough acrylic film stays flexible and helps prevent peeling by letting moisture escape.
When you need a product that stops peeling paint, Zinsser’s Peel Stop is the product that will do the job. Easy to use, it can be used on internal and external surfaces, and application equipment easily cleaned with soap and water. Peeling paint is typically caused by moisture build-up, aged paint that no longer adheres to a surface or substrate well, or from a paint coating that was applied to a chalky surface. In using Peel Stop, you are essentially gluing down the edges of peeling paint, preventing them from popping or curling back up. This primer will allow for successful adhesion of a new topcoat, without any more paint peeling off again.
Zinsser Peel Stop is a clear, flexible and binding primer, designed for surfaces that are peeling, chalking, or cracking. Even after painted surfaces have been scraped and sanded, tiny cracks and gaps remain under the edges of old paint. Peel Stop seeps into these spaces and ‘glues’ them down, forming a tight bond that helps stop future peeling. The special formula penetrates and binds chalky residues.
Applied over cracked or crazed surfaces, Peel Stop acts as a flexible bridging primer to seal crazing and prevent the finish coat from cracking, providing a sound surface for primer and paint.
Recommended for application to problem interior / exterior painted surfaces that exhibit chalking, alligatoring, cracking, flaking, and peeling.

Zinsser Peel Stop is recommended for application to the following substrates:
- Exterior Surfaces – Previously painted wood siding, windows, doors, fences, and trim; dry and denatured timber; metal gutters and downspouts; masonry siding, walls and foundations (inc. cured concrete, stucco, concrete block, brick, vinyl and galvanised siding, etc.)
- Interior Surfaces – Previously painted drywall, plaster, cement, concrete, or stucco walls and ceilings; wood doors, windows, baseboards and trim.
Thorough surface preparation is very important. Surfaces should be clean, dry, sound and free of dust, dirt, grime, grease, oil, wax, mould, wallpaper adhesive, or any contamination that may interfere with adhesion. If unsure, always wash surface with an appropriate cleaning solution or solvent. Surfaces must be thoroughly scraped and sanded to remove all poorly adhered paint. Lightly sand exposed wood to remove loose fragments. Dull glossy painted areas with sandpaper.
Spot prime areas where paint has been scraped or sanded off. In most cases only one coat is necessary. Excessively porous surfaces may require a second coat.
Shake or stir well before using. Do not thin. Apply with brush and/or roller or airless sprayer. Back brush or roll to work Zinsser Peel Stop into cracks and edges of old paint. Proper application of Zinsser Peel Stop will dry to a slight sheen. Apply a second coat if dull spots appear. For best brushing performance use quality, synthetic bristle brushes (natural bristle brushes are not recommended).
Apply when air and surface temperatures are between 10° and 32°C and humidity is less than 80%. Lower temperatures and higher humidity can prolong drying time. If conditions do not permit prompt drying, allow Zinsser Peel Stop to dry overnight before priming or painting. Do not apply if rain is expected and primer or topcoat cannot be applied before rain occurs.
Priming & Top Coating
Any water based or alkyd primer or paint may be used over Zinsser Peel Stop. As Peel Stop is clear, we recommend priming with Zinsser Bulls Eye 1-2-3 or Zinsser Cover Stain, followed by a coat of quality water based or alkyd paint to assure optimum results.
- Zinsser Peel Stop is formulated to help prolong the adhesion of existing paint coatings and is not intended as a substitute for proper surface preparation or for use on surfaces where paint failure results from chronic or excessive moisture intrusion
- Repair any source of moisture intrusion before attempting to repaint
- Ongoing paint failure may require complete removal of the existing coating system
- Not for use on floors, exterior decks or surfaces subject to immersion or prolonged contact with water

Can I use Zinsser Peel Stop as a stabiliser before applying Sandtex Masonry Paint? I've scraped off bubbling paint etc but I am concerned about stopping paint edges peeling and chalky patches.
Yes absolutely, Zinsser Peel Stop can be overcoated with most types of paint so any water based or solvent based Sandtex Paint will be fine.
