Laminin Coatings Laminin Coatings
  • Ensure colour and sheen level consistency by painting from the same production batch. Tint bases contain fewer litres than advertised.
  • Allow 7 days for paint to dry properly and 30 days to reach full strength. Do not wash or abrade newly painted surfaces until properly cured.
  • To achieve opacity and formulated sheen level adhere to specified spreading rates. Over spreading will lead to poor opacity and will compromise the quality and longevity of the coating.
    Applying the paint too thick will result in sheen build up, sagging and mud cracks of the coating.
  • Adhere to specified over coating times. Premature over coating might lead to poor opacity, compromised film thickness and finish.
    Temperature will influence drying and over coating time.
  • Do not touch up as this will lead to poor opacity, sheen and colour variations. When doing repairs, paint from corner to corner.

The condition of the surface greatly influences the stability and durability of your paint.

Painting over cold substrates might lead to permanent pinholes and craters in the paint film.

Painting over hot substrates might lead to permanent pinholes and blisters in the paint film or delamination from substrate.

Spreading rate is the amount of paint that needs to be applied per square meter to achieve the formulated wet and dry film thickness (WFT / DFT). Dry film thickness can be measured.

Spreading rates are theoretical and are based on smooth flat non penetrating surfaces.

  • To ease application:
    Sand and wash (with sugar soap and rinse thoroughly with clean water) previously painted surfaces.
  • All Coastal exteriors exposed for more than 24 hours must be rinsed with clean water to remove salt deposits before recoating.
  • Remove all loose flakes and apply a Laminin specified primer/undercoat to obtain a stable surface.
    To even out interior plasterwork, apply a scraper coat of your desired Laminin skimming compound and sand to an even finish.
    It is recommended to apply a plaster primer before application of topcoat.
  • Use quality application tools (roller, brush etc.) to avoid poor opacity,
    Stir paint well with a flat paddle to achieve a homogeneous base that will ensure film consistency.

Rising damp: the upward movement of water from capillary action in the lower sections of walls and other ground supported structures. It rarely rises above 1.5m.

Penetrating damp (moisture ingress) is descending and/or lateral and might be as a result of rain.

  • Sand, cement mixtures, plasterwork, concrete and screeds needs to comply with SABS 1090 standards and SABS 0164-1 in terms of MPA strength
  • Do not paint or skim over surfaces with a moisture content above 15%, measured using an ultrasonic Protimeter or similar approved. In the case of a WME (pin type) measurement, reading must be below 5%
  • For moisture damaged areas the root cause must first be addressed before painting can commence
  • Try to avoid painting in moist / humid conditions. To prevent damage to the paint film, there should be no rain forecast for at least 7 days
    Do not paint in direct sunlight as this will result in the paint drying to fast leading to visible “lap-marks”. Windy conditions might have a similar effect and can cause a deposit of dust particles on the wet paint.

Efflorescence: the white salt deposits often seen on paint film after moisture has passed through. This can cause damage like discolouration, peeling, flaking and blisters.

Colour variations due to efflorescence (alkaline burn or attack) will not be covered under product failure.

  • Colours tinted that fall outside of Laminin Largo’s formal tinting system may have risks regarding poor opacity, early fading, UV resistance, over and under tinting or alkaline attack.
  • Do not alter factory standard colours as this will compromise the products longevity i.e. fading, UV and alkaline resistance, colour consistency and opacity.
  • Bright colours play an important role in colour selection, even though Laminin only makes use of lightfast pigments certain bright colours have a natural tendency for poorer opacity and UV resistance and might be more prone to alkaline attack.
  • The colour, white, may require a 3rd topcoat to achieve opacity and full obliteration.
