Bollom Broflame Ultra Basecoat is a white, water-based fire protective basecoat for bare and previously painted interior wood. When finished with a specified Bollom Flameguard Ultra topcoat, it provides a choice of decorative finishes as part of the tested fire protection system.
The complete system is tested to BS EN 13501-1:2018, achieving B-s1, d0 or B-s2, d0 depending on the specified topcoat and surface. These classifications mean:
Suitable for bare and previously painted interior timber at least 9mm thick. Existing decorative coatings must be limited to four sound, firmly adhering coats. Apply the basecoat and compatible Flameguard Ultra topcoat according to the manufacturer's specification for the surface and required fire classification.
Choose from the following compatible topcoats to complete the system.
| Product | Use |
| Bollom Flameguard Ultra Gloss Topcoat | Solvent-based topcoat for a gloss finish over Broflame Ultra Basecoat |
| Bollom Flameguard Ultra Vinyl Matt Topcoat | Water-based topcoat for a vinyl matt finish over Broflame Ultra Basecoat |
Wooden surfaces must be sound, clean and dry before applying Bollom Broflame Ultra Basecoat.
Please note: Paint applied before the 1960s may contain lead. Take appropriate precautions when preparing or removing old coatings.
Always apply to a small test area before starting to check adhesion and the final appearance. Follow the manufacturer's instructions on the tin and in the technical data sheet.
Please Note: During application and drying, air and surface temperatures must remain between 5°C and 30°C, with relative humidity below 75%. For airless spraying, use a pump such as a Graco Ultra Max II or equivalent, a tip size of 0.019-0.029" (0.48-0.73mm), a tip pressure of 3500psi (approximately 241bar) and a hose with an internal diameter of 0.375" (9.5mm).
Allow the final coat of Bollom Broflame Ultra Basecoat to dry for at least 24 hours at 20°C before applying Bollom Flameguard Ultra Gloss, Acrylic Eggshell or Vinyl Matt Topcoat. Overcoating is essential to complete the tested fire protection system.
Follow the application and aftercare instructions for the chosen topcoat.

What fire protection rating does Bollom Broflame Ultra Basecoat achieve?When finished with a specified Bollom Flameguard Ultra topcoat, the system is tested to BS EN 13501-1:2018, achieving Class B-s1, d0 / Class B-s2, d0. The classification depends on the surface and complete coating system used. Follow the technical data sheets for both products.
Can I apply Bollom Broflame Ultra Basecoat over existing paint?Yes, provided the existing finish consists of no more than four coats of sound conventional decorative paint that adhere firmly to the timber. Remove loose or flaking paint and wet abrade existing gloss or eggshell finishes before application. The timber must be at least 9mm thick.
Does Bollom Broflame Ultra Basecoat need a topcoat?Yes. It must be overcoated with Bollom Flameguard Ultra Gloss, Acrylic Eggshell or Vinyl Matt Topcoat to complete the tested fire protection system. It cannot be left as the final finish.
Can Bollom Broflame Ultra Basecoat be applied by roller or spray?Yes. Apply by brush, roller or airless spray. When using a roller, brush over the wet coating to achieve a smooth finish. Airless spraying requires suitable equipment and the settings specified in the technical data sheet. Do not thin the paint.
How many coats are required and what is the coverage?Apply two coats at 5m² per litre per coat. A 5-litre tin therefore covers approximately 12.5m² with both coats. Maintain the specified coverage rate, as the required coating thickness is essential to the tested fire performance.
How long should I wait between coats and before topcoating?At 20°C, allow at least 4 hours between basecoat coats and at least 24 hours after the second coat before applying a Bollom Flameguard Ultra topcoat.
