Methods of epoxy application and clamping will differ depending on what you are laminating. Because of large surface areas and limitations of wet lay-up time, roller application is the most common method for applying epoxy. Apply thickened mixtures with an notched spreader. Using staples or screws is the most common method of clamping when you laminate a solid material to a solid substrate. An even distribution of weights will work when you are laminating a solid material to a base that will not hold staples or screws, such as a foam or honeycomb core material.
Vacuum bagging is the ideal clamping method for laminating a wide range of materials.
Through the use of a vacuum pump and plastic sheeting, the atmosphere is used to apply perfectly even clamping pressure over all areas of a panel regardless of the size, shape or number of layers.
