Peelaway 7 Application
How to use Peelaway 7
Peelaway® 7
Peelaway® 7 paste is formulated to safely remove multi-layer combinations of household, architectural and industrial paints and varnishes. Effective on those based on acrylic, polyurethane and cellulose, both solvent and water-based, including those containing lead. Can be used on virtually all interior and exterior surfaces, vertical and overhead and is excellent for intricate, carved and moulded surfaces.
The paste is applied by spatula, brush, trowel or sprayed over the surface to be stripped, and covered with the Peelaway® poultice blanket for the required time (dwell time). When stripping is complete the blanket, paste and paint are removed with the cover retaining paint which may contain toxic particles from the old paint preventing them becoming airborne.
Features and Benefits:
- One application removes multiple coats of most paints, varnishes and high-performance coatings.
- Environmentally / user safer as it does not contain Methylene Chloride, N-MethylPyrrolidone (NMP), highly flammable solvents or Caustic Soda.
- Safe for use on virtually all interior and exterior surfaces.
- Surfaces stripped do not require neutralising.
Caution: Delamination may occur if Peelaway® 7 is used on veneers and plywood, dependant on the glue present, so dwell time should be minimised. Some plastics and composite/resin-based surfaces such as gesso or paper-based wicker may be damaged by Peelaway® 7.
Limitations: Peelaway® 7 will work more slowly under 5°C and will stop working under 0°C. Will not remove certain two pack epoxy coatings, baked enamels, cement-based paints or bitumen. It is essential that a test patch of Peelaway® 7 is carried out before use, to determine the residual effect of Peelaway® 7 on the surface being stripped as well as its effectiveness in removing any coatings.
1. Preparation
Please read all the instructions and safety information before starting work.
Cover and protect areas where stripping is not desired, including adjoining surfaces and floors where overspray may travel. Polythene sheeting and masking tape create an effective barrier. Plants should be covered during application. Do not sand flakes of paint if suspected to contain lead. Stir well before use and where Peelaway® 7 has started to dry out within the tub, adding small amounts of water at a time whilst mixing will return the paste to its original consistency. Remove any hard deposit and rehydrate in a small amount of water, then return to the bulk product. Store product in a cool and dry area, always replace lid firmly after use.
Safety Directions: Wear appropriate personal protective equipment (PPE) such as Viton or equivalent, or Butyl rubber (HSE INDG330 Guide) gloves, overalls and eye/face protection to protect against skin contact. If in doubt speak, to your PPE supplier and show them this label/product or call us for further advice. In case of spillage wash affected area with plenty of water. Ensure adequate ventilation when working indoors. Store product in a cool and dry place, keeping product away from children and animals. Always replace lid after use.
2. Test Areas
Before using this product always conduct a Test Patch.
Twin Test patch kits are available from your local Peelaway® supplier or directly from Barrettine. The Test Patch kit consists of both Peelaway® 1 and Peelaway® 7. A test patch should be completed before undertaking any paint removal project, on an area typical of the surface to be stripped and including irregular as well as flat surfaces. This will confirm that the correct Peelaway® system, poultice thickness and dwell time has been selected, for clean and safe removal. Every project is different, making it vital that a test patch is always carried out. It is the responsibility of the end user to determine the suitability of the Peelaway® product with the substrate and coatings to be stripped.
Once a small test patch has confirmed that the Peelaway® product selected has worked we strongly recommend that larger areas are tested before starting your stripping project. This will allow a more accurate estimate of the thickness and time required to complete the stripping process. We would also recommend that the full clean-up process and any subsequent coatings intended to be applied are tested, to confirm compatibility after use of Peelaway.
Barrettine accept no responsibility or liability with regards to any damage or unsatisfactory results caused using Peelaway® products.
Troubleshooting: Dwell time too short – the process has not completed so removal may be difficult, particularly in crevices. Dwell time too long – substrate could be damaged due to excessive water absorption or drying out of the poultice can occur. If the poultice dries out it will be difficult to remove but can be rehydrated by lifting the blanket and spraying with warm water, then re-covering for 5 minutes. This should be repeated until it softens. Alternatively, another layer of Peelaway® 7 can be applied over the top.
3. Application
Apply Peelaway® 7 poultice by spatula or brush between 1mm to 3mm thick, working the poultice into crevices and mouldings. Ensure direct contact with substrate and on uneven surfaces, follow up with second coat to confirm that the minimum thickness is met all over, if necessary. Older coatings and numerous layers will require the thickest application.
Place the Peelaway® 7 blanket (printed side out) onto the poultice, excluding air as much as possible. Rub gently to remove any bubbles, piercing large ones if necessary. Masking down edges will decrease the chance of the poultice drying out.
Allow a dwell time of 30 minutes to 48 hours, checking the test patch at intervals. The poultice should be removed after the shortest effective dwell time. Thicker/numerous paint layers and low temperatures will require the most time.
External use may be affected by extremes of weather conditions (rain or direct sunshine) and additional monitoring or protection may be required. Tape down blanket edges to protect from high traffic or the possibility of rain/wind. Only apply to an area size that is manageable and that can be stripped within the timescale indicated by the Test Patch.
Application by Airless Sprayer: Dilute up to 1 part water to 5 parts Peelaway® 7 and mix thoroughly until an even consistency is reached. We recommend an airless sprayer suitable for heavy materials with a medium to coarse tip size. Adjust pressure/nozzle as required to achieve an even spray.
Coverage: Coverage will vary, depending on the number of layers, type and age of paint to be stripped. It is essential to carry out a test patch to determine the thickness required and dwell time before stripping. As a rough guide, coverage is 1m2/kg for each mm of thickness.
4. Removal
Ease the Peelaway® spatula under the poultice and gently pull the blanket from the surface, keeping the paint, paste and cover together as much as possible. Remove any remaining residue with the spatula before commencing cleanup. Intricate areas may need gentle encouragement with
a small soft-bristled brush. Any remaining coating residue is usually pre-softened and can be removed in a few hours with a further application of Peelaway® 7. Collect material removed and dispose of in compliance with local regulations.
Clean-up: Use polythene sheeting to protect adjacent surfaces from splashback and run-off. Once the original surface is revealed, clean the stripped surface with water using a sponge, scrubbing brush or wet/dry vacuum. If needed, use a nylon bristle brush to loosen the remaining residue. Avoid soaking the substrate or wetting for prolonged periods and allow the stripped surface to dry thoroughly. Power washing may damage porous substrates.
Special Considerations
Lead-Based Coatings: Residue/waste containing lead should not be allowed to dry out and generation of dust should be avoided. If airborne lead particles are suspected, a dust mask should be worn.
Plaster Substrates: Saturation of plaster with water can lead to surface deterioration. Care should be taken to select the shortest effective Peelaway® dwell time to reduce the risk of this. Remove as much Peelaway® 7 residue manually as possible and after stripping, do not immediately wash down with water. Allow the plaster to dry thoroughly, then clean up with a soft dry brush as required. Only wash down with water sparingly if necessary and do not re-apply Peelaway® 7 to plaster surfaces as it can damage the surface.
