We use this product applied first, in conjuction with Frekote 700-NC Release agent to be used as the second step of protection. Shelf Life is about nine months.
FREKOTE FMS mold sealer application instructions
Mold Preparation: The mold surface must be clean and free of any release agent or other contaminants for FREKOTE FMS to be completely effective. Remove any contaminants with Rexco-Formula Five Wax and Mold Stripper-S Super , Rexco - Formula Five Mold Cleaner or a suitable cleaning solvent. Light industrial abrasives can be used to remove heavy resin build-up, do not use any grit higher than what the tool has been prepared to.
Only a thin wet film is required. Wipe on a smooth, thin, continuous, wet film (Low lint Paper towel or microfiber is a good application method). Avoid wiping over the same area that was just coated until the solvent has evaporated (Making sure not to miss any areas during the application). It is suggested that small areas be coated working progressively from one side of the mold to the other. Only work in a few square feet at one time until you are comfortable working with this product. Within seconds of applying the FREKOTE FMS, the solvents will evaporate and the applied area should be wiped clean with a lint free microfiber cloth. We recommend applying FREKOTE FMS in a four step process. 1) Apply the FREKOTE FMS in an up and down motion, 2) Apply side to side, 3) Apply at a +45 degree angle, 4) Apply at a -45 degree angle. By doing this it will ensure that any areas missed will be covered in one or more of the four step coating process.
When Appling these 4 or more base coats of FREKOTE FMS, allow several minutes after each application for complete solvent evaporation (work on another section of the mold in the meantime). The film should be dry and not feel tacky (If the mold feels tacky it’s a sign that you have applied way too much of the product or you are not wiping the mold good enough after the solvents are evaporating.
Flammability/ Storage: FREKOTE FMS contains flammable solvents. The product should always be used in well ventilated areas. Store in a cool, dry place. Keep container tightly closed when not in use.
