|Patch Aid is designed to improve the working properties of traditional gel coat spray patches. This is achieved by thinning the gel coat, minimizing orange peel, speeding the cure, and reducing surface tackiness.
Patch Aid mixed with gel coat will provide these properties:
Low color, which results in excellent spray patches
Low viscosity, for easier spray and less orange peel
Longer working time, advantageous for repairing large defects and for mold resurfacing.
Light stabilized, to minimize discoloration of patches made using clear and pigmented gel coats.
Good surface cure, which minimizes sandpaper "gumming".
Excellent sanding and buffing.
Easy mold resurfacing.
Patch Aid also eliminates the need to thin, side-promote or add wax to gelcoats prior to patching.
1. Mix patch aid thoroughly.
2. The recommended ratio mix 25%-33% Patch Aid to gel coat. To this mix, add correct amount of MekP Hardener/Catalyst. Mix and spray.
3. The acceptable method for measuring small quantities of MEKP is with a syringe. Even a thinly sprayed layer will be ready to sand in approximately one hour and hard enough to buff soon thereafter.
4. Care must be taken not to over-or under-catalyze, which may affect color.
5. Working time is approximately five minutes.
Precautions: Always shake or mix before using. This assures a uniform mixture that will perform the same, from the first patch to the last. If Patch Aid has been allowed to become cooler than 70 F, it could become cloudy and, at this point, would no longer be a homogeneous solution. The material should be brought to room temperature and returned to its original appearance before using. Catalyzed masses get very hot as they cure. Excess catalyzed patching materials should be placed in a bucket of water to cool.
