Exterior Paint Prep Kit — Big Jobs

If you’re painting the entire exterior, you don’t want to run out halfway through sealing.

The Big Exterior Pre-Paint Seal Kit is built for those big jobs, when you’re sealing multiple walls, long cladding runs, eaves, architraves and trim before paint.

Same professional system.
Just doubled.

Designed For Bigger Exterior Jobs

Before fresh paint goes on, the gaps need attention.

Cladding lines that have opened up.
Eaves against quad.
Exterior architraves around doors and windows.
Small separations where trim meets brickwork.

Interior gap filler won’t survive outside. It cracks and fails.

This kit uses a paintable polyurethane sealant designed for outdoor movement and weather exposure. It flexes with temperature changes and bonds properly to exterior materials.

Seal it. Let it cure. Paint over it.

Built For Exterior Conditions

The polyurethane included in this kit:

• Handles expansion and contraction

• Bonds to common cladding and masonry

• Withstands weather exposure

• Is fully paintable once cured

Available in:

• White – best for lighter paint colours

• Grey – better suited to darker finishes

Choose based on your final exterior colour scheme.
