ECOSEAL Plus™ Sealant

ECOSEAL Plus™ Sealant

Knauf Insulation ECOSEAL Plus™ with Gasket Pro Technology, is a fast drying, water-based elastomeric spray that seals penetrations and joints in the building envelope, as well as provides a gasket between studs and drywall. ECOSEAL Plus™ dries to a flexible tough film and has great bond strength with low odor and zero V.O.C’s. ECOSEAL Plus™ should be used with Knauf Insulation EcoBatts® or Knauf Insulation Premium Blowing Wool Insulation.  Together, they form the ECOSEAL Plus™ System—a high performance, continuous and affordable air and thermal barrier for the building envelope.

Kit Description

ECOSEAL Plus™ was engineered to utilize commonly available airless spray equipment. This helps keep costs low and allows easy maintanence.  Knauf Insulation has collected all the compo-nents in a convenient kit that contractors will need to start sealing immediately. These components include a GRACO Ultra Max 795 Airless Sprayer with 50 feet of hose, a 6 foot whip hose, spray gun, two nozzle extensions, tip guard and two spray tips. Also included is a hose reel, a digital display and an adapter/plug to enable the usage of two hoses simultaneously. Replacement parts and other accessories can be purchased at most paint supply stores.


Knauf Insulation ECOSEAL Plus™ is applied directly from the bucket, with no thinning or mixing. Using an airless sprayer, typical drying time allows the installation of EcoBatt Insulation or Knauf Insulation Premium Blowing Insulation in just a few hours, in most cases. Once cured, it remains flexible over a wide range of temperatures. ECOSEAL Plus™ is designed to be installed by trained applicators.  For training, go to
