Note: Minimum overcoating times with same treatment or with fillers are as a guideline only. As soon as the Gelshield Plus is firm enough it can be overcoated, even if the surface is still tacky. At temperatures of 10-15°C it is recommended that the fast cure versions of Interfill 830 and Interfill 833 be used.
APPLICATION AND USE
Preparation: OSMOSIS TREATMENT: Gelcoat should be removed by blasting, or by peeling plus a light blasting. The resultant substrate should be carefully examined and professionally evaluated as chemically dry. Surface must be clean and dry prior to application of Epiglass HT9000 or Gelshield Plus. Contact International for further details.
Method: OSMOSIS TREATMENT: Apply initial coat with a thin foam roller and work into the surface using a brush. (Alternatively, Epiglass can be used as the first coat of the cycle). Remove excess paint with a brush making sure a minimum of 150 microns wet film thickness is applied (Minimum 150 micron wet film thickness is not essential when Epiglass is used as the first coat in the cycle). Fill as required using, Interfill 830, Interfill 833 or Watertite. At temperatures of 10-15°C it is recommended that the fast cure versions of Interfill 830 and Interfill 833 are used. If filler "set" to an extent that the surface does not move under light pressure, then overcoating can proceed. In other words, the filler should be sanded prior to application of Gelshield Plus. Apply a further 3 coats of Gelshield Plus by roller, each coat at least 150 microns. At shorter overcoating intervals, a "wet on tacky" application technique can be employed. As soon as Gelshield Plus is firm enough it can be overcoated with itself, even if the surface is still tacky.
Hints/Useful Tips: Mixing: Stir contents of each part prior to mixing. Mix the base and curing agents of Gelshield Plus together at the specified mixing ratio. Stir well before use. Pour immediately into a wide flat tray to prevent premature curing.
Thinning: Do not thin under any circumstances.Cleaner Epoxy Thinners No. 7 for equipment cleaning only. Ensure equipment is cleaned before product has gelled.
Other: If self-on-self overcoating times are exceeded, abrade surface thoroughly to remove gloss. The minimum overcoating times given are guidelines only. In some instances, depending on curing conditions, substrate temperature etc, the next coat may be applied faster than this. If the final coat overcoating times are exceeded, abrade with 80 grit paper before application of Gelshield 200. If cold, and before mixing, store Gelshield Plus at room temperature for 12 hours or stand in containers of warm water to warm product up to approximately 15°C. Excessive warming will severely reduce pot life. When applying by roller, spreading with a brush will help release any air bubbles. If the laminate requires re-building Epiglass resin should be used. Do not use Gelshield Plus for any laminating work. Before antifouling can be applied a tie coat of Gelshield 200 is needed.
Some Important Points: Gelshield Plus is not suitable for application directly on the gelcoat. Do not use at temperatures below 10°C. If a 'wet on tacky' technique is not used, and an overnight cure is allowed between coats, care should be taken that a very thin surface film or 'amine sweat' has not formed. In the event that this does happen, it can be removed by washing with warm water with a little detergent added. Then rinse with fresh water and allow the surface to dry before proceeding with the next coat. Product temperature should be minimum 15°C/59°F and maximum 35°C/95°F. Ambient temperature should be minimum 10°C/50°F and maximum 35°C/95°F. Substrate temperature should be 3°C/5°F above dew point and maximum 35°C/95°F.

TRANSPORTATION, STORAGE AND SAFETY INFORMATION
Storage: GENERAL INFORMATION:
Exposure to air and extremes of temperature should be avoided. For full shelf life of Gelshield Plus, ensure that the container is firmly closed between uses and the temperature is between 5°C/41°F and 35°C/95°F. Keep out of direct sunlight.
Gelshield Plus should be kept in securely closed containers during transport and storage.
Safety: GENERAL: Read the label safety section for Health and Safety Information, also available from our Technical Help Line.
DISPOSAL: Do not discard tins or pour paint into water courses, use the facilities provided. It is best to allow paints to harden before disposal.
Remainders of Gelshield Plus cannot be disposed of through the municipal waste route or dumped without permit.
Disposal of remainders must be arranged for with local authorities.
