Brush On a Better Seal
- 1Inspect the area
Confirm that the issue is a minor, accessible crack, gap, or seepage point. Stop if the leak is major, recurring, structural, or unsafe to reach.
- 2Clean and dry the surface
Remove dirt and dust, clear standing water, and let the area dry before opening the jar.
- 3Test a discreet spot
Apply a small amount where the finish is less visible. Check that the gray coating suits the surface and existing finish.
- 4Brush on a controlled coating
Use the included natural-bristle brush to cover the suitable crack or gap with steady, even strokes. Avoid blocking drainage or fixtures.
- 5Close and store the jar
Secure the screw-top lid after use and keep the compact kit ready for future minor maintenance.

Questions and answers
It is intended for suitable moisture-prone surfaces around roofs, exterior walls, windowsills, bathrooms, and kitchens. Clean and dry the area, then test a discreet spot first because existing finishes and materials can vary.
Use it for minor accessible surface sealing, not structural damage, unsafe roofing, major active leaks, or persistent flooding. Serious or recurring water intrusion needs qualified professional assessment.
Yes. The three included pieces are the sealant jar, product box, and natural-bristle application brush.
Coverage depends on the width, depth, and condition of the crack or gap, so a fixed area cannot be promised. The 100G jar is best suited to focused minor repairs rather than coating a large surface.
Renters can use it for suitable minor surface seepage where they have permission to make the repair. Test the finish first, especially because the coating is gray and can remain visible on light surfaces.
Yes. Remove dirt and dust, let standing moisture clear, and prepare the surface before brushing on the sealant. Applying over contamination or water can interfere with contact.
