Peelaway® 1 Paint & Varnish Remover is formulated to remove multiple layers of old toxic lead paint from ornate plaster ceilings and cornices, bricks, masonry, steel, cast iron and woodwork. Water based alkaline formulation. Works for up to 48hrs.
Peelaway® 1 is water-based and most often used for restoration projects involving multi layers of oil based paints where the stripping compound is formulated to quickly react with the paint resins and convert any lead present into a compound that can be safely disposed of without endangering the environment.
ALWAYS CARRY OUT A TEST PATCH FIRST.
We can not state enough how important it is to carry out a test patch before general use.
The size of the test patches will depend on the subject matter, but as a guide they should be from 75 x 75mm up to 300 x 300mm. Apply Peelaway® paste graded from 1mm to 6mm thick according to the age and thickness of the coating (e.g 1mm when removing a thin layer of varnish but possibly up to 6mm where there are multiple layers of thick paint). Place the Peelaway® blanket (print side out) on to the paste. Rub gently to remove air, pierce bubbles where necessary. Allow to stand from 2 to 48 hours, again this will be determined by the paint/coating type and thickness/number of layers. When using Peelaway® 1 to remove heavy paint build up over plaster mouldings you may need to leave even longer (up to 72 hours) and this can often aid the drying out process which encourages the old paint and blanket to lift away from the substrate being treated to complete the stripping process.
For areas involving different elevations several test patches should be applied to accommodate the possibility of different coatings and the effects of weather on exterior surfaces. To remove, the spatula should be inserted into the paste and a section gently lifted away. If the original surface is apparent, the test patch can be removed and the surface wiped with a damp sponge. If paint can still be seen, the test patch should be replaced and re-examined after a few hours.
Once the correct paste and timing for the project has been established together with the thickness required, the designated paste should be applied, the Peelaway® blanket laid over the paste and left for the time indicated by the test patch. Full instructions are on the containers.
Each project can potentially give different results and this is why it is imperative to carry out Test Patches. Leaving on for not long enough could mean the process has not completed. Leaving on too long could damage the substrate or you may find the Peelaway® blanket and paste becomes too hard and difficult to clean up.
Peelaway 1® is a high pH product, so it can penetrate and react with the oil/lead content of multi layers of older coatings, this means that the stripped surface should be neutralised with a weak solution of acetic acid (supplied with the packs) and left to dry thoroughly before repainting.
During very damp periods/conditions such as autumn through to spring, particularly on exterior substrates, moisture containing residues of Peelaway 1® may bleed out of the substrate at a later date thus raising the alkaline pH value once again. This could affect the repainted surface. As a precaution if Peelaway 1® is used and the surface is to be repainted, we would always recommend using a good quality alkaline resistant acrylic sealer/primer prior to repainting.
However if the surface is not to be repainted, the pH or moisture content of the surface is not so critical.
Peelaway 1®should not be used on gesso (a form of putty) mouldings sometimes used on apparently carved fireplace surrounds.
Peelaway 1® should not be used to remove paint from veneers, plywoods, aluminium or unskimmed drywall and may discolour certain hardwoods. e.g Oak, Mahogany,Teak etc (use Peelaway® 7).
Note: Must be neutralised before repainting with the neutraliser supplied in the pack.
