Self Guide Primer Filler EVO
Self Guide Primer Filler Evo is an innovative, acrylic, high solid, two-component primer/filler with a 4:1 mixing ratio, available in standard colours, black, grey and white.
Features & Benefits
- High solid content - creates high build, which can be adjusted by adjusting the percentage of thinners
- New concept hardener - catalysis occurs in all directions in the product, giving much better dimensional stability of the product - no sinking
- Immediately matches the colour, even with finishes which contain clear pigments - can easily be covered with 95% of paints, even those that usually require an undercoat
- Easy to sand - direct sanding with P320 / P400 grit. Finish with P500 / P600 grit for light colours
- Changes colour during sanding (black turns into neutral grey) - acts as a guide coat avoiding use of spray matt black. Also highlights defects not usually seen with coloured fillers
- Excellent drying - easily sandable without clogging the abrasive paper, if used according to instructions
- No build-up of paint solids at the bottom of the tin - does not need shaking in tinting machine
To avoid condensation, be sure the surfaces to be treated are at room temperature (at least 18°/20°C) and not damp.
High humidity conditions may cause loss of adhesion after few weeks with the eventual appearance of large blisters.
It is not sufficient to wipe off condensation with a cloth but you have to wait that the whole surface reaches room temperature (about 2 hours – depending on type and size of surface).
By sanding, remove the black protective film on new plates.
1. Before applying SGPF EVO, carefully clean and degrease the surface removing any trace of dirt and rust.
2. Thoroughly clean using Acrysol or Panel Degreaser to eliminate any wax and silicone polishing materials, grease, dirt, fingerprints.
3. To ensure a complete adhesion, sand carefully the surrounding area of the part to be treated using only one kind of abrasive paper: P240/P320.
2 or 3 layers of filler are able to cover as well the signs of a P150/P180 paper..
4. Apply a first light coat of the primer/filler 4:1 in volume (6:1 in weight) on the whole area to be repaired, which can be thinned up to 25% with an acrylic thinner, using a standard primer filler gun with a 1.8-2.0 nozzle and using a pressure of 2.5-4.0 bars and a fanlike spray, not too open.
If required, add Ipercure accelerator, at maximum concentration of 4%.
5. Wait for the proper flash off time before applying the next coat.
6. Never apply coats too thick to avoid blistering, cracking, sags or slow drying
7. In case of high temperatures, ensure the product arrives wet (glossy) on the surface.
8. After application of the required number of coats, verify they are completely dried before starting to sand. Time depends upon thickness: about 4 hours at 20°C and 30 minutes at 60 °C.
9. To speed up drying and to ensure dry through (when applying several / thicker layers) use I.R. lamps. Always wait few minutes before turning lamp on in order to allow a proper flashing off of solvent and to avoid causing it to boil creating unpleasant blistering effects. Follow the lamp manufacturers instructions which should give safe distances and periods of drying dependent on power.
Possible black holes after sanding indicate defects onto the surface to be painted (stones, holes, etc… ): they should be removed before starting painting.
Can be over painted with all water or solvent bases.
Note = Pot life of hardened product is about 1 hour at 20 °C.
