• Application substrate should be cleaned of loose debris, dirt, oil, wax, grease and other contaminants the surface must be moisture and frost-free.
• Install backing material as needed.
• The depth of the joint should be 1/4" (6 mm) minimum to 3/8" (9 mm) maximum.
• Sealant can be applied with standard or bulk caulking guns, manual trowel or spray application.
• Apply sealant in opening and work into all areas eliminating voids or seams and making complete contact with substrate.

• Mix INSS0285 SPRAY thoroughly using a power agitator before application.
• Thinning is normally not required, if necessary, use potable water (3% max.) to adjust viscosity.
• Apply via airless spray equipment in a single pass not more than 1mm WFT to prevent sagging.

• Surface skinning may occur in a partially filled container in which case filter the material before use.
• Wet film thickness approx.1mm cures to 0.64mm dry film.
• Thickness measurement - wet film thickness of the sealant layer can be measured using a wet film thickness gage.
• The dry film thickness can be verified using calipers or micrometers.

• Not for use in areas immersed in water.
• The sealant can only be removed mechanically once cured.
• This product is not intended for use in fire-rated construction.
