    Features & Benefits

    • 4 Properties in 1 Paint
      1. Fire Resistant protecting your homes, schools, hospitals etc
      2. Non Toxic & Emission Free not harmful to you
      3. Durable robust and designed to last
      4. Excellent Coverage saving time and money
    • Best possible reaction to fire resistance classification turning combustible surfaces fireproof in both walls and ceilings, perfect for protecting wood
    • Painting wooden particle walls transforms them from a combustible non-fire rated wall to a fire-classified wall that can be used as part of a fire compartment system
    • Painting on top of existing paints, both water and solvent based will protect the old surfaces against fire making FR-1 ideal to upgrade fire safety in existing buildings without having to tear down and rebuild construction elements. Perfect for upgrading architectural protected buildings where walls, ceilings, doors, covings etc. are required to be kept in their original form and material
    • Non-toxic and emission free with near zero VOC and best possible emission classifications makes the paint perfect for anyone not wanting to breathe toxic chemicals and especially people suffering from asthma, allergies or any other breathing related diseases
    • Durable, robust and designed to last, can be cleaned with a damp cloth without the risk of washing off the paint. Durability is especially important on surfaces where abrasion occurs, for instance walls in hallways and staircases. The paint is not designed for use on floor surfaces
    • Excellent coverage with a spray applied one-coat system which is cost effective saving paint and especially application time. Brush and roller applications can also be performed, often in only two coats. No topcoat needed
    • Suitable for most surfaces, including concrete, bricks, masonry, primed steel, wood, gypsum, plastics and most non-porous surfaces, in most cases without a primer
    • Halogen free with added preservatives that resist bacteria and fungal growth providing extra protection to health in addition to the non- harmful emissions, and it also protects the underlying substrates
    • The paint is not intended for application on bituminous substrates or substrates that can exude certain oils and plasticizers or solvents, and is not recommended for use in constant humid areas
    • The paint’s durability is expected to be at least 12 years making it a cost effective option when compared with normal paints with limited durability
    • Do not apply in very damp or humid conditions or extremes of temperature




    Before painting ensure the surface to be painted is clean, dry and free from grease, dirt, dust, and other contaminants. Remove any old or flaking paint until you have a sound surface; if in doubt remove all existing coatings. Please see the primer section further below.



    For roller and brush application, dilute the paint with water. The paint can be diluted up to 20% (by volume), but 5% is the preferred amount.

    Add the water into the paint while stirring thoroughly to ensure complete mixing. Use a medium pile roller and apply no more than 150µ in one coat to get the best results. Increase the WFT loading required for the fire protection by the amount the paint was diluted, for example, if the fire protection loading was 370µ and the paint was diluted by 5% the loading that now needs to be applied is ~390µ WFT.

    Alternatively to ensure the correct loading has been applied simply apply all of the FR-1 paint specified to coat a given area regardless of how much it was diluted. Remove excess paint from the brush or roller on the rim of the paint pot and then wash brush/roller with water.



    The paint can be applied in one coat using spray equipment, for example, the Graco X-Force Spray Gun with a tip size 17-21thou. The paint can also be diluted for spraying but the fire protection loading would need to be adjusted as described above.

    Protecta Interior Paint FR-1 can normally be applied without a primer, but there are a few exceptions.

    Interior Paint FR-1 should not be applied directly onto gloss paints.

    Zinsser Bulls Eye 123 Primer can be used as a tie coat to give Interior Paint FR-1 good adhesion to previously painted surfaces including gloss surfaces (P360/039). Knots and stains should be sealed before applying Interior Paint FR-1.

    Case Studies

    Protecta Interior Paint FR-1 is now available for use on Transport for London projects.

    Following the sad loss of life from the fire at Kings Cross Station in 1987, Transport for London implemented a scheme restricting the use of combustible building materials in any rail projects. Products proposed for use on London Underground, Cross Rail, Network Rail and HS2 projects have to be tested and evaluated in terms of their reaction to fire, toxicity of combustion gases and the density of smoke generated before given the green light for use.

    Interior Paint FR-1 ticked all of the boxes and is now available for use in Transport for London rail premises, both subsurface and overground.
