For face fit you may need an extra hand. Take frame and hold against existing frame. Make sure it’s level with the top and sides of the existing window frame. With the face fit shutters there is a cover strip which is in the middle of the frame. Take this out and you will see holes where to screw the frame to the window frame. There is no need to use all the holes as it’s a bit of an overkill. Just use aprrox 3-4 top, 3-4 on bottom 3-4 on both left and right sides. On the back of your cover strips there are small strips of double sided tape. Just take off the back of each little strip and then reinsert into frame. This will hide all the screws and make your frame look great.
Once your frame is screwed on grab you panels and put them onto the frame. One part of the hinge is already on the frame with the other part on the panel. Just put into place and put the pins provided into the hinges. You may have to loosen the screw that is in the hinges to adjust the height of your panels. Once you have the desired height then grab the small screws and finish screwing off the hinges. There should be 3 screws per hinge. Now grab the little white buttons and put into the screws that were screwed into panel (this will hide the screws).
Now that’s all done you will need either white or a timber colour gap filler and put a bead between your window and shutters. Congratulations you have completed your shutters.
