Leaking seams

Cover narrow joints and connection points where water can enter.

02

Damp walls

Add a protective coating over prepared cracks and porous areas.

03

Hard-to-reach gaps

Use the spray for coverage and the included brush for precision.

COMMON QUESTIONS

Frequently Asked Questions

Can it be used outdoors?

It is marketed for indoor and outdoor household repair areas, including roofs, exterior seams and window edges. Apply only in suitable weather and keep the area dry while curing.

Do I need the brush?

The spray works well for broader coverage. The brush is useful around corners, vertical seams and areas where overspray should be minimized.

Can I spray over a wet leak?

For better adhesion, remove standing water and allow the surface to dry whenever possible. Clean away dust, grease, loose material and old flaking coatings before application.

How many coats should I apply?

Use thin, even coats rather than one heavy layer. Additional coverage may be applied after the previous layer has set, depending on the size and condition of the repair area.

Is it suitable for major structural leaks?

No spray coating should replace professional repair where there is structural damage, active pressurized leakage, electrical risk or a large opening. Address the underlying cause before cosmetic finishing.
