    General

    Paper is a mat composed mainly of cellulose fibres derived from either a chemical or mechanical

    pulping process, may be bleached or unbleached, with or without resin additives for wet-strength,

    and with or without surface treatments, such as coatings or machine calendaring. Paper for the

    most part, presents an excellent surface for painting and waterborne paints are excellent in this

    area. They are normally applied direct to paper. There are however some areas where the use of a

    solventborne sealer, such as Resene Sureseal (see Data Sheet D42), is advisable.

    • Yellowing of unbleached paper - unbleached paper in the presence of U.V. light will yellow

    due to the formation of dye-like substances. This may cause discolouration of the first

    coat of a waterborne paint applied directly to the paper. Use of Resene Sureseal (see

    Data Sheet D42) stops this.

    • In steamy areas, such as kitchens, bathrooms and laundries, the use of Resene Sureseal

    (see Data Sheet D42) upgrades the performance of the paper.

    • Old wallpaper:

    (a) Wallpaper should be checked prior to painting to determine the condition of the

    coating used. Some old wallpapers used a weak coating, which provides an unsatisfactory

    base for painting. If the old coating will come off as a powder when scratched with a fingernail, a sealer such as Resene Sureseal (see

    Data Sheet D42) or Resene Waterborne Smooth Surface Sealer (see Data Sheet D47a) will condition the surface successfully.

    (b) Wallpaper printed with metallic links should have a test area painted to ensure there is no reaction with paints. Any sign of

    staining would indicate that sealing with Resene Sureseal (see Data Sheet D42) is necessary.

    (c) Some vinyls contain plasticisers that can migrate into the paint and leave the paint soft and sticky. Test a small area

    with the topcoat paint, if the area remains tacky after 24 hours seal the wallpaper with Resene Vinyl Wallpaper Sealer (see Data

    Sheet D406).

    • Paperfaced plasterboard:

    Problems may occur due to differences in the porosity of various stopping layers and the paper surface of the paperfaced plasterboard.

    For new construction projects ensure that the appropriate level of finish is specified especially if critical lighting conditions exist.

    Surface preparation

    D84.1 Clean surfaces

    Thoroughly wash down with Resene Paint Prep and Housewash (see Data Sheet D812) to remove all dirt, dust, grease, chalk, cobwebs

    and other contaminants. Rinse thoroughly with clean water. Clean with soft cloths as abrasives will damage the paper surface. Allow

    to dry.

    D84.2 Remove all moss and mould

    Thoroughly clean down to remove all loosely adhered material. Treat areas of moss or mould infestation with Resene Moss & Mould

    Killer (see Data Sheet D80), correctly diluted with clean water. Leave for up to 48 hours to achieve full kill. For heavy infestations

    further applications may be needed. Wash thoroughly with clean water to remove residues.

    D84.3 Pretreat surfaces (level 5 finish only)

    Allow to dry out thoroughly, then pretreat with a full coat of Resene Broadwall Surface Prep & Seal (see Data Sheet D807) by roller

    to achieve a uniform finish. Lightly sand with a pole sander to produce a smooth surface and wipe with a clean, damp sponge to

    remove dust.

    As a spray only option Resene also offers Resene Broadwall 3 in 1 (see Data Sheet D810). Coverage rates are dependant on the

    number of coats applied, refer to Data Sheet.

    D84.4 Seal surfaces

    For wet areas, such as kitchens and bathrooms, allow to thoroughly dry out, then seal with a coat of Resene Sureseal (see Data

    Sheet D42) or for new wet areas a coat of Resene Waterborne Smooth Surface Sealer (see Data Sheet D47a). For dry areas, allow to

    thoroughly dry out, then seal with a coat of Resene Broadwall Waterborne Wallboard Sealer (see Data Sheet D403).

    To minimise the occurrence of sheen banding (seeing the position of the jointing compounds after painting) sealing the plaster and board

    D84.4 can be done prior to the application of Resene Broadwall 3 in 1 (see Data Sheet D810) or Resene Broadwall Surface Prep & Seal (see Data

    Sheet D807).
