Car Builders TXT Coating 1K - Black

TXT Texture Coating is an Australian-designed and manufactured 1K textured underbody car paint, meaning it does not require a hardener. The advantage of not having to catalyse an entire tin allows you to cap it and save it for later. If you finish spraying and there is still paint left, simply unscrew the tin, clean out your gun, seal the bottle, and keep it for another application.

The bottle comes fitted with a Schutz connector, making it easy to use with your Schutz spray gun.

This versatile coating provides reliable defence against impacts, scratches, rust, and moisture—perfect for areas where long-lasting durability is needed.

Recommended applications include:

• Wheel arches
• Underbody floorpans and chassis
• Interior panels and trims
• Protective stone guard coatings

Its advanced 1K formulation offers excellent adhesion to metal, aluminium, fibreglass, plastic, and wood.

Looking for the toughest version?

For maximum durability, or if your project involves UV-exposed areas (such as external bodywork, trailers, toolboxes, or bar work), we recommend upgrading to 2K TXT Coating . The 2K formula provides enhanced toughness and is designed to stand up in sun-facing applications.

Comes as a complete kit with hardener included

Durability

Strong protection against impacts, scratches, rust & moisture

Maximum toughness, chemical resistance, and long-term durability

UV Resistance

Best for non-UV areas (wheel arches, underbody, chassis, interior)

Designed for UV-exposed areas – but suitable for all 1K applications too

Reuse

Reseal tin for future use

Must be used once catalysed

Applications

Wheel arches, underbody floorpans, chassis, interiors, stone guards

Everywhere 1K can be used plus external bodywork, trailers, toolboxes, bar work

Finish

Textured protective coating

Texture can be adjusted for coarse or finer finish

Colour

Black

Black or Tintable (add automotive colour code to achieve any colour)

Compatibility: TXT can be applied over acrylics, epoxies, and urethanes. Note: the solvent in TXT will attack alkyd-based paints (enamels and NC lacquers). Always test a small sample when painting over unknown coatings.

Q. Do you do a 4L kit?

A. Simply purchase 4 × bottles. TXT Coating does not require a hardener, so you can buy any quantity you need—without committing to a full “kit.”

Coverage per 1L tin:

• 1 coat – 2.7 sqm to 3 sqm
• 2 coats – 1.35 sqm to 1.5 sqm

IMPORTANT: TXT Texture Coating 1K is incompatible with enamel paints.

Specifications

SURFACE PREPARATION

Bare metal, aluminum and galvanized steel - abrade with a minimum 80-180P sandpaper. Clean surface with solvent based wax and grease remover or isopropanol, ensuring surface is free from dust, grease, oils and contaminants.

TXT can be applied direct to metal however, for best corrosion protection we suggest using a suitable primer such as etch or epoxy direct to metal then applying TXT.

If allowing primer to fully cure, you will need to treat this as a cured painted surface and abrade the primer to ensure maximum adhesion.

Rigid Plastic / Fiberglass - abrade with a minimum 80-180P sandpaper. Clean surface with solvent based wax and grease remover or isopropanol, ensuring surface is free from dust, grease, oil and contaminants. TXT can be applied direct to Rigid plastic /fiberglass surfaces.

Flexibly plastics - abrade with a minimum 180-240P sandpaper, clean surface with solvent based wax and grease remover or isopropanol. We recommend using a plastic adhesion promoter before applying TXT coating to ensure best adhesion.

Wood – TXT can be applied directly to wood, avoid using liquid solvents to clean, make sure wood is dry and free from dust and contaminants.

MIXING

Black TXT coating in tin is ready to apply, no decanting, hardener or reducer is required.

Shake tin for a minimum of 3 minutes immediately before applying to ensure successful mixing of coating.

APPLICATION

DO NOT APPLY BELOW 5°C

Spray Gun – suction feed Underbody Schultz guns are designed to screw directly to the TXT coating tin, use with a minimum 4mm tip. NOTE Test gun operation before attaching to coating tin.

Air pressure – 50-100psi (3.45 –6.9 bar) Higher pressure will give a finer texture, air pressure should be tested before application to achieve desired result.

Spray Distance – 20-25cm (8-10inches)

Application – Spray in an even overlapping pattern, apply a minimum of 2 coats

Coat 1 – Aim for 95% coverage, allowing flash off between coats 10mins @ 25°C (in colder conditions increase time frame between coats)

Coat 2 – Aim for 100% coverage, If spray pattern is visual on completion of final coat simply increase spray distance to 45-60cm and lightly spray over the surface with 45° passes to haze texture and even out the coating, do this until the desired finish is achieved.

DRY FILM BUILD (theoretical)

1 x Coat = 100µm, 4.0mils (0.1mm)

2 x Coats = 200µm, 8.0mils (0.2mm)

DRY TIME

Touch dry in 3-4hrs @25°C, allow 5-7 days for full cure with exposure to UV

Dry time can be reduced by baking, not recommended exceeding 60°C

COVERAGE

Approx. 2.7m2 - 3.0m2/L , tested with application by schultz gun at 70PSI

CLEAN UP

Clean equipment with solvent based gun wash, acetone or thinners.

STORAGE

Keep in a well-ventilated area at room temperature away from direct sunlight.
