Extreme Seal Vehicle Floor Waterproofing Paint is a professional-grade polyurethane-alkyd coating designed to give long-lasting waterproofing, impact resistance, and slip protection to van floors, trailer beds, loading bays, and mobile workspace interiors. Formulated with high-solids resins and anti-corrosive pigments, it creates a flexible yet tough protective membrane that locks out moisture, prevents rust, and extends the service life of timber, metal, GRP, and concrete flooring systems.

Unlike standard floor paints that chip or wear away under heavy use, this vehicle floor sealer is engineered to withstand rolling loads, foot traffic, trolleys, cargo movement, and repeated cleaning with detergents or solvents. Its integrated silica-textured finish provides dependable anti-slip performance even when wet, giving tradespeople, mechanics, dog groomers, valeters, and mobile service operators a safer and more professional working environment.

The paint dries to a low-sheen satin finish that disguises scuffs and makes routine wash-downs faster and easier. For smooth or highly porous surfaces, use Extreme PU Floor Primer & Sealer beforehand to maximise adhesion and prevent delamination.

Manufactured in the UK under ISO 9001 quality assurance, this waterproof van floor paint is available in a range of durable colours to suit both domestic DIY users and fleet professionals.

Suitable Substrates:

  • Timber ply floor linings in vans and trailers

  • Steel and aluminium floors (abraded and degreased)

  • GRP and fibreglass panels

  • Sound concrete workshop bays

  • Previously coated 1-pack paints (abraded)

Primer strongly recommended for smooth galvanised steel, very porous concrete, or brittle substrates.

Available Colours:

Post Red • Black • Dark Grey • Light Grey • Mid Green • Blue • Yellow • White • Orange

Custom BS / RAL shades available for bulk orders over 80L.

Coverage & Spread Rate:

  • Smooth ply or metal surfaces: 5–7 m² per litre per coat

  • Porous concrete (first coat): ~4 m² per litre

  • Two thin coats are recommended to achieve optimum film build and long-term performance.

Drying & Curing Times (@ 18 °C):

  • Touch dry: 4–6 hours

  • Recoat: 6–8 hours

  • Light foot traffic: 12 hours

  • Load cargo: 24 hours

  • Full chemical resistance/cure: 7 days

This rapid curing profile ensures vehicle downtime is kept to a minimum while still delivering industrial-grade protection.

Storage & Clean-Up:

  • Store sealed containers between 5–30 °C, away from open flames, sparks, or ignition sources.

  • Clean brushes, rollers, and spray equipment immediately after use with white spirit or standard thinner.

  • Always reseal tins firmly between uses to avoid skinning.

Safety Notice:

Extreme Seal Vehicle Floor Waterproofing Paint is a solvent-based, flammable coating. Apply only in well-ventilated areas with adequate airflow. Avoid inhalation of vapours and prolonged skin contact; protective gloves, eye protection, and a respirator (if spraying) are recommended. Keep away from ignition sources and out of reach of children. Dispose of waste responsibly in line with local environmental regulations. For full health and technical advice, consult the product’s Safety Data Sheet (SDS).

Extreme Seal Vehicle Floor Waterproofing Paint is specifically engineered for vehicle interiors and mobile workspaces where moisture, impact, and wear are daily challenges. It is ideal for:

  • Commercial vans and trailers: sealing timber ply linings, aluminium, and steel floors against water ingress and corrosion.
  • Mobile service units: mechanics, valeters, dog groomers, and cleaners who require a waterproof, easy-to-clean, non-slip surface.
  • Specialist conversions: food-prep vans, catering trailers, and mobile workshops that demand hygiene, safety, and chemical resistance.
  • Utility bays and load areas: preventing rust and rot from spills, wet boots, and constant cargo movement.
  • Workshop or garage bays: extending the same waterproofing protection to concrete or GRP floors exposed to heavy traffic and solvents.

With its textured satin finish, this coating combines professional durability with safety, helping to protect assets and create a more efficient, long-lasting workspace.

Application Instructions

Surface Preparation

  • Metal (steel/aluminium): Degrease with solvent, abrade with P120 grit, and vacuum clean.
  • Timber (ply lining): Sand to fresh surface, countersink screws, and vacuum.
  • GRP / previously painted floors: Key with P180 grit and solvent wipe down.
  • Ensure all substrates are completely dry (wood moisture < 4%).
  • For smooth, galvanised, or porous surfaces, apply PU Floor Primer & Sealer and allow ~12 hours to dry.

Paint Mixing & Application

  • Stir thoroughly for at least 2 minutes before use.
  • Do not filter (pre-textured with silica for anti-slip performance).
  • First Coat: Apply a thin, even coat (approx. 100 µm wet film) by brush or roller.
  • Second Coat: After 6–8 hours at 18 °C, apply a cross-directional second coat (target 50 µm dry film build).
  • Maintain ventilation during application; avoid heavy use during the first 24 hours.

Spray Application (special order smooth version only)

  • HVLP spray with 1.8 mm nozzle; thin up to 10% with xylene.
  • The anti-slip textured version is roller/brush application only.

Curing Schedule

  • Touch dry: 4–6 hours.
  • Light foot traffic: 12 hours
  • Cargo loading: 24 hours

Full chemical resistance: 7 days
