Megafiller is two-pack solvent-free epoxy filler that allows very thick applications with minimal shrinkage. Because of its very low specific weight (SG 0.57), high thicknesses of Megafiller can be applied without significantly affecting the weight of the hull. Though hard and with high cohesive strength, Megafiller has outstanding sanding properties.
Megafiller has a very low water absorption and is therefore suitable for above and below-water
application. Suitable as part of an epoxy coating system on metal, GRP or wood substrates.

Apply at a temperature between 10°C and 35°C. The temperature of the substrate should be minimum 3°C above the dew point of the air. The temperature and the relative humidity should be
measured in the vicinity of the substrate.
Mix the two components thoroughly, in their correct proportions with
a knife until the colour is perfectly even
Drying times are generally related to air circulation, temperature, film thickness and number of coats, and will be affected correspondingly. The figures given in the table are typical with:

1 Provided the surface is free from chalking and other contamination prior to application, there is normally no overcoating time limit. Best intercoat adhesion occurs, however, when the subsequent coat is applied before preceding coat has cured. If the coating has been exposed to direct sunlight for some time, special attention must be paid to surface cleaning and mattening/removal of the surface layer in order to obtain good adhesion.
The given data must be considered as guidelines only. The actual drying time/times before recoating may be shorter or longer, depending on film thickness, ventilation, humidity, underlying paint system, requirement for early handling and mechanical strength etc. A complete system can be described on a system sheet, where all parameters and special conditions could be included.
Clean, dry and undamaged primer or blast cleaning to Sa 2½ (ISO-8501-1:1998/SS 055900). Apply onto suitable undercoats such as Megacote or Megaprimer. Sand Megafiller before covering it (to help adhesion of the subsequent coat). For best results, cover with Megafiller Smooth then
