No.2 High Build Surfacer is a two component new technology high build epoxy surfacer and profiling compound.
No.2 High Build Surfacer is designed to fill and profile minor imperfections such as found on epoxy glass lay-ups, sanded epoxy fairing compounds, and repair sites on damaged structures.
No.2 High Build Surfacer is NOT a fairing compound and should NOT be overbuilt.
The recommended maximum dry film thickness per coat is 0.5mm (500 microns).
No.2 High Build Surfacer may be applied by spray or squeegee, or a combination of both.
No.2 High Build Surfacer is suitable for service above and below water however in immersion service a full epoxy barrier system should be applied over the sanded No.2 High Build Surfacer.
No. 2 High Build Sanding Surfacer should always be sealed with No.3 Primer/Undercoat, or No.4 Epoxy Sealer Undercoat, prior to topcoating, to ensure there is no loss of gloss in the applied Elite Polyurethane.
