ECA Expert Says...

Customers Favourite ! New hybrid polymer formulas allow a very versatile and strong grab adhesive and sealant. Internal / external. Works with damp surface. 2O min open time before curing and bonding. Much stronger than traditional neoprene panel adhesives. May be painted. 

For ultra strength use Shark SP350.

G B H Hybrid Polymer Adhesive Sealant - 310ml gunnable tube


Our new product GBH is a strong adhesive and sealant using advanced hybrid polymer technology.
GBH will seal and stick even in damp conditions. GBH offers almost limitless benefits as a sealant and adhesive all in one and overcomes application barriers associated with conventional adhesive/silicone products.

GBH will give a strong initial grab bond but will be moveable whilst positioning.

GBH will achieve excellent long term performance in a wide range of external and internal construction joints.

GBH can also be sanded and overpainted.

GBH is solvent free & odourless

GBH can be applied to wet surfaces (that will eventually dry)

GBH will work on most materials and substrates


GBH is ideal for skirting boards, architraves, timber battens etc. where a strong bond is required.
GBH can also be used on metal, plastics, ceramics, porcelain, natural stone, brick and even mirrors (test before use)
GBH can also be used externally for bonding a wide range of substrates.
GBH is ideal for the perimeter sealing around windows and doors as it is weather and aging resistant.
GBH is an ideal substitute for applications where an Acrylic caulk is used as it flexible and can be overpainted with no shrinkage.

Not recommended for continuous immersion or sanitary applications
