Product Description

Rubbol Primer Plus is a premium quality primer/undercoat, for use on timber in exterior and interior locations. Also suitable as a mid coat for protection of steel, non-ferrous metals and hard plastics, pre-treated according to prescribed system.

Application Description

Timber surface must be abraded, clean and dry, with dust, dirt, wax and grease removed. Mould and algal growth must be
eradicated using a suitable solvent. The moisture content of the timber must not exceed 18%. This figure will be 14% or
lower for interior timbers. Degrease any exposed bare timber surface by wiping with a cloth dampened in a suitable solvent.
Any hard crystallised resin at the surface of the timber should be removed with a scraper. Remaining resinous residues may
be removed using a suitable solvent. Knotting may be used to reduce extractive discolouration, however, knotting is not
always fully effective in “sealing in” resin. In addition, the adhesion of subsequent coatings may be impaired. New Timber : Where a superficial application of preservative to softwood and hardwood is deemed necessary, such as timbers in Durability Class 3 or lower, use Cuprinol Wood Preserver Clear (BP). For Class 4 (in ground contact) and 5 (marine) use pre-treated wood specific for these conditions. Preservative pre-treatments must be fully dry before the application of Rubbol Primer Plus. Do not use on substrates which have had water-repellent preservative pre-treatments applied. Where possible, the first coat should be applied all round prior to fixing.Only use non-ferrous screws, nails and fixings.

Tips & Advice

  • 1. Preparing the Surfaces
    Timber surface must be abraded, clean and dry, with dust, dirt, wax and grease removed. Mould and algal growth must be
    eradicated using a suitable solvent. The moisture content of the timber must not exceed 18%. This figure will be 14% or
    lower for interior timbers. Degrease any exposed bare timber surface by wiping with a cloth dampened in a suitable solvent.
    Any hard crystallised resin at the surface of the timber should be removed with a scraper. Remaining resinous residues may
    be removed using a suitable solvent. Knotting may be used to reduce extractive discolouration, however, knotting is not
    always fully effective in “sealing in” resin. In addition, the adhesion of subsequent coatings may be impaired.
    Where a superficial application of preservative to softwood and hardwood is deemed necessary, such as timbers in Durability Class 3 or lower, use Cuprinol Wood Preserver Clear (BP). For Class 4 (in ground contact) and 5 (marine) use pre-treated wood specific for these conditions. Preservative pre-treatments must be fully dry before the application of Rubbol Primer Plus. Do not use on substrates which have had water-repellent preservative pre-treatments applied. Where possible, the first coat should be applied all round prior to fixing.
    Only use non-ferrous screws, nails and fixings.
    Base stained/primed : Denib using a fine grade nylon abrasive pad or a fine grade (P240 or finer) wet or dry silicon carbide abrasive paper, in the direction
    of the grain. Do not break through the surface coating. Remove all dust.
    Note: Where there is localised damage, or deterioration has occurred as a result of exposure of the factory coating for longer than 3 months, affected areas should be thoroughly sanded back to a sound substrate.
    All damaged or decayed timber must be removed and replaced, cutting at least 25mm into sound timber. When splicing in new sections consider whether the timber species’ natural durability is sufficient. Brush apply two coats of Cuprinol Wood
    Preserver Clear (BP) to saturation. Thoroughly treat timbers, especially end grain sections, and ensure they are fully dry before splicing in. Secure with non-ferrous fixings and fill all voids surrounding the spliced-in area with a suitable repair compound such as Dry-Flex from Repair Care
  • 2. Cleaning
    Clean brushes and equipment with brush cleaner immediately after use. If spilled, Rubbol Primer Plus may be removed immediately while still wet using white spirit.
  • 3. Storing
    Store in cool, dry, frost-free conditions
