splintered wooden shutter
How to fix your issue
with J-B WeldStar
Step 1: Clean surface, removing any dirt or debris. Use Sandpaper as needed to remove any rough edges of crack/splinter.
Step 2: Knead KwikWood with your fingers and apply to the crack, using additional product to fill gaps or holes in the shutter if needed. Note: if wanting to match a wood stain, apply stain to Kwikwood while working with your fingers, adjusting color as needed until matching.
Step 3: Allow KwikWood to fully dry and cure, about an hour.
Step 4: If desired, KwikWood can be sanded and painted.
