Expert Verdict — Reviewed by the SuperArbor Pro Desk
Use #9300 for spot repairs and detailing rather than full coatings; it excels at permanent patches over punctures and sealing fastener lines. Clean and prepare the membrane surface first, and apply at the minimum 1/8 in. thickness, adding material on porous or irregular surfaces. Note it is solvent-based, so verify compatibility with your specific membrane before use.
Solvent-based silicone mastics require ventilation and should be kept away from ignition sources; follow the safety data sheet during application.
