Weldbond features a clog free cap that prevents it from ever drying out. One of the best white glues around - it's non toxic so there's no fumes, and it dries crystal clear. It's made for interior or exterior use. ART TIP: For a crackled, textured effect, apply a dark colour of oil base paint and allow the surface to dry. Brush on a coat of Weldbond Glue and let glue set until tacky (but not dry completely). Choose a complimentary colour of acrylic paint and brush on as the final layer. As it dries, watch the crackles appear!
