ATG Turbo Glue is the most advanced adhesive in the framing industry. Stronger than ATG tape. Fast to apply and dries in seconds. Acid free and water soluble while wet, it allows for easy reposition when applied without any damage. Perfect for gluing matboard, backing of frames, book dust covers and much more. ATG Turbo Glue works perfectly to adhere matboard together and attach covers on both wooden or poly frames. To join matboard, apply dots of adhesive around the opening of the mats and press. To attach paper or fabric covers to the back of a frame, apply a 1mm bead using the pre-pierced pin hole applicator tip, to the outside edges of the frame as you would apply ATG tape. Position the cover in place and press. ATG Turbo Glue will not dry out or deteriorate over time.
