Laminating Corners & bandaging Lay a 200mm square piece of the mat on the roof deck and ‘wet it out on both sides with resin (see catalyst addition chart) using a 2½” polyester roller. Place the mat onto the face of the adjoining trims with the bottom edge on the radius of the trim. Fold around the corner and fold over the top of the trim down onto the deck. It will be easier to dress and feather if the mat is cut vertically from the top corner of the trim upwards. Using the 2½” roller, 2” paintbrush, and small consolidating roller, feather the corners into place. Any joint in the trims should be bandaged using the same mix of resin, in a similar fashion to the corners.
If any boards are not completely engaged these joins should be bandaged, even a small gap may cause the resin to leak through the boards which will lead to porosity in the laminate. If any nails holding the trims are not going to be covered with laminate on the deck or corners they should be laminated with a small piece of mat. The deck of the roof can be laminated before the corners and bandages have cured.
Hints and tips on how to Laminate tapes
Using woven tape can be a little tricky for a novice. Potential problems
Cut shorter strips
Apply the main roof CSM over the woven during the laminating process
Use strips of CSM matting instead of the Woven bandage cut into Max 2m lengths (Roll up before laying for ease of application)
*Please note this video shows using CSM Tapes, this method works fine, CRS recommends woven tape for strength and long-term integrity
Fibreglass woven tape is a versatile and strong material that is commonly used in fibreglass roofing installations. The tape is made from woven fibreglass fibers, and is designed to provide added strength and stability to the roofing. It is used to reinforce joints and seams, and to prevent leaks by filling any gaps or cracks in the roofing material. The tape is easy to use, and can be applied quickly and efficiently. It is also flexible, which makes it easy to wrap around curves and corners, and it is resistant to water, UV rays, and other environmental factors. Additionally, fibreglass woven tape is compatible with most adhesives and resins, which makes it an ideal choice for a wide range of roofing applications.
