SG91
Gel putty for filling

Light white putty-gel specifically formulated for fairing the surfaces to the final shape, used for filling and leveling of counterparts and bulkheads, for filling bubbles, defects and bonded joints, smoothing and manual start-up of large surfaces. Particularly suitable for smoothing over 5 mm and for filling where a gel time of more than 25 minutes is required. The excellent leveling and sandability are accompanied by a low shrinkage and an intense white color that facilitates overpainting with gelcoat, significantly increasing the application yield.
To meet the most demanding finishing specifications, it is advisable to add the finishing putty (SG90) to the gelcoat.
