Note: Once the sandable time has been exceeded, all fillers should be sanded before overcoating to promote good adhesion. A sanded filler may be left for a period up to 3 months before being overcoated with further epoxy filler or with Interprime 8-series. After 3 months the filler must then be re -sanded before overcoating.

APPLICATION AND USE
Preparation: PREVIOUSLY PAINTED SURFACES
In Good Condition: Wash with Super Cleaner, rinse with fresh water and allow to dry. Sweep blast or abrade with 180-280 grit paper.
In Poor Condition/Repairs: All previous coatings should be removed back to solid material and filled with Interfill 830.

INTERFILL: 830 Sand with 80-180 grit paper.

BARE GRP/COMPOSITE: Sand smooth with 120-180 grit paper. Remove all sanding residue using a clean air line and sweeping with a clean brush or broom. Vacuum clean for best results.

Method: Mix the two components thoroughly to an even colour. Remove any dust from the surface. Apply firmly in a spreading action. When hardened, sand smooth with 80-180 grade wet or dry paper. Interfill 833 may be overcoated with itself as soon as it has cured enough not to be lifted during the screeding process.

Useful Tips: Thinner International GTA220 for equipment cleaning only.
Ventilation and Humidity Control: Avoid conditions of low temperatures coupled with high humidity as this can result in the formation of a non-adherent contact surface which will need to be removed by detergent wash followed by fresh water rinse, or by sanding, prior to the application of any subsequent layers.

Other: Spread mix out on a board to avoid excess heat build up and to keep the working life as long as possible. To ensure good filling of minor pinholes and defects in the Interfill® 830, move the spreading blade backwards and then forwards over the area.Some Important Points Do not use unless mixed thoroughly with the curing agent at specified ratio. Do not apply more than recommended WFT at any one time. Do not use below 10°C/50°F. Product temperature should be minimum 10°C and maximum 35°C.
Substrate temperature should be minimum 10°C and maximum 35°C. Ambient temperature should be minimum 10°C and maximum 35°C. Do not thin. Do not wipe down cured filler with thinners/solvents.

Compatibility/Substrates: Interfill 833 should be applied over cured, sanded epoxy fillers such as Interfill 830 or on cured GRP/Composite.
