Every coatings removal project is different. To ensure that you have the correct product for yourproject it is essential to perform a test patch on all coatings that are to be removed. There are amultitude of different coatings and they all react differently to chemicals applied to them. The onlyfast and reliable method for determining which product will be most effective is to apply a test patch.

Application (all coating removers)
For best results, surface temperatures should be 10–30°C and approximatively 50% relative humidity. Product efficacy will be substantially reduced if applied outside of these conditions. It is important to perform a small inconspicuous test area on each type of substrate and paint coating prior to full application to ensure product effectiveness. The dwell time required for softening/lifting paint will vary according to the number of layers, type of coating being removed and surface temperature. It is important to note that the different coating removers will have different levels of performance and limitations.
Dulux Precision Coatings Remover (Green)
May not be suited to the removal of some epoxies, lead based paints and primers as well as some high performance coatings. Do not use the Dulux Precision Coatings Remover range on plastics, vinyl, acrylic sheeting, plasterboard, composite decking, EIFS, MDF, particle board, laminates, veneers and rubber. These surfaces will suffer from irreversible swelling or destruction of the substrate surface if exposed to any of the Precision Coating remover range.
Dulux Precision Premium Coatings Remover (Blue):
Not recommended for use on some plastics (flexible PVC unless it is part of a wall paper removal), most fiberglass, Plexiglas (acrylic sheeting), Polycarbonate sheeting, flexible rubber compounds and EIFS (Polystyrene) systems, as the active agents in the coating remover will plasticise these materials, permanently damaging their properties. Care should be used when removing paint from smooth limestone, lime bound composite stone, including marble, rendered plaster and plasterboard, and cement based boards as the acid in the coating remover will react with the alkaline nature of these substrates, damaging the surface or the structural integrity of the substrate. For these surfaces it is recommended to use Dulux PRECISION Coatings Remover (green). Care should be taken when removing paint from MDF, Particle Board and OSB (Oreinted Strand Board) as the surface particles of the board will swell and remain "furry" after removal of the paint requiring either heavy priming with a Level 5 primer, or a small amount of mechanical abrasion to smooth the surface. In some cases the coating remover will have a slight impact on reactive metals like galvanized steel and zinc and aluminium, but this will generally be minimal.
Dulux Precision Restoration Coatings Remover (Red):
Danger! Corrosive! Avoid skin and eye contact. Wear protective gloves and glasses and or full face mask This product is a light red/pink paste with low odour. Direct contact with the eyes may cause severe burns with possible corneal damage and blindness. Skin contact may cause chemical burns. Vapours or mists may cause irritation to the eyes, mucous membranes and respiratory tract. See product SDS for full OHS details.
Timber
Precision Restoration Coatings Remover is NOT SUITABLE for use on timber substrates. We recommend the use of Dulux Precision Coating Remover (Green) or Dulux Precision Premium Coating Remover (Blue) instead.
Other substrates
Do not use near or with Aluminium equipment or equipment with aluminium contacting components. Not recommended for use on veneered plywood, plywood, masonite, plasterboard, aluminium, sandstone, limestone, fibreglass, glass laminates, plexiglass, plastics (including vinyl), rubber or EFIS.
Previous coatings
Not recommended for the removal of 2-pack epoxies, elastomeric coatings, urethanes, chlorinated rubber, cementitious paint, baked finishes and other high performance coatings. For these coatings, we recommend the use of Dulux PRECISION Coatings Remover (GREEN) or Dulux PRECISION Premium Coatings Remover (BLUE).
Dulux Precision Coatings Remover Neutraliser
When using Dulux Precision Restoration Coatings Remover (red), a further neutralisation step is required following the coatings removal process. This is most important since Dulux Precision Restoration Coatings Remover is an alkaline paste and the treated surface must be neutralised before any recoating of the surface can be done.
Disposal (all)
Always investigate and confirm disposal means allowed in the jurisdiction that you are operating before starting a job. It is important to know what is allowed and the costs of doing so in order to properly quote the finished removal costs.
Remove any loose or peeling paint prior to application. Mask/protect areas where stripping is not desired. Perform a small inconspicuous test on each type of surface/paint coating to be removed before general use to determine compatibility, yield, proper thickness and dwell time needed.
Dulux Precision Coatings Remover Test Patch Kit
Dulux Precision Coatings Remover Neutraliser
When using Dulux Precision Restoration Coatings Remover (red), a further neutralisation step is required following the coatings removal process. A small sample of the neutraliser is included in the test patch kit to treat any area where Dulux Precision Restoration Coatings Remover has been tested.
1. Dilute sample with 500ml water
2. Use a plastic bottled wand type sprayer to thoroughly coat the test area with neutraliser - on vertical walls, start at the top of the wall.
3. Allow the substrate to dry and test for pH using pH test strips. The surface can be considered successfully neutralised when the pH is no greater than 8 and moisture content no greater than 14%. Dulux Precision Neutraliser can be applied at any point after final rinsing but is most effective when applied to a dry substrate so it is advisable to wait for at least 24 – 48 hours after final washing of the treated substrate particularly when neutralising porous surfaces. Refer to Dulux Precision Neutraliser for more details on how to treat the surface correctly after coating removal.
