FAQs

Can I use this product indoors?

It is strongly recommended to use this only outdoors or in very well-ventilated areas due to the nature of the aerosol formulation.

How long should I wait between coats?

Allow 15-20 minutes of drying time between each thin coat for the best structural integrity.

What should I use to clean up spills?

Use white spirit to remove any overspray or accidental spillages.

Is it safe to leave this in a hot shed?

No, store the can in a cool, dry place away from heat sources and direct sunlight.

Can I paint over the black sealant?

Yes, once the sealant is fully cured, it can be painted over to match your existing decor or exterior surfaces.

Does it work on wet surfaces?

No, the surface must be completely clean and dry before application to ensure the sealant bonds properly.

Troubleshooting

Nozzle is clogged and not spraying

Soak the nozzle in white spirit or replace it if the obstruction is too hardened to clear.

Sealant is running or dripping

You are holding the can too close or applying too much material at once; hold the can 15-25cm away and use thinner, more controlled bursts.

Sealant isn't adhering well

The surface likely has invisible contaminants or moisture. Clean the area thoroughly with a degreaser and ensure it is bone dry before re-applying.

Pros and Cons

Pros

  • Excellent adhesion to multiple substrates
  • Resistant to UV rays and harsh weather
  • Simple spray-on application process
  • Overpaintable once dry
  • Ideal for both emergency and preventative maintenance

Cons

  • Strict temperature requirements for application
  • Requires proper ventilation due to spray fumes
  • Cannot be applied in direct sunlight
  • Requires regular shaking during use to prevent settling

Setup, Compatibility & Care

Before starting your project, ensure the ambient temperature is between 15C and 25C to guarantee the formulation cures correctly. Always perform a patch test on an inconspicuous area first to check for chemical compatibility. After you finish spraying, always invert the can and press the nozzle for 2-5 seconds; this clears the internal straw and prevents the nozzle from clogging with hardened sealant. Store the can in a cool, dry place away from direct sunlight when not in use.
