Hempel Sealer 599 - 750ML
Hempel Sealer 599 is a two-component epoxy-polyamide sealer with low viscosity and good penetration ability. For saturation of glass fibre laminate, when gel coat has been removed (repair of osmosis damage). For priming of ferro-cement boats and boats of wood that can absorb the sealer.
For use on wood and plywood. For saturation of glass fibre laminate, when gelcoat has been removed (repair of osmosis damage). For interior and exterior use both above and below the waterline
Minimum Application Temperature : 10°c

Preparation & Application
Glass fibre: All loose/defect gel coat must be removed and any absorbed moisture must have evaporated before applying the product.
Ferro-cement: Any loose surface layer (e.g. laitance) must be removed by sanding or abrasive sweeping. The moisture content of the concrete must be below 3%.
Wood: The wood must be completely dry, moisture content below 16%, and should not be primed with any ordinary priming oils or commercial antimould fluids. The wood must be capable of absorbing the sealer completely.
APPLICATION CONDITIONS: The surface must be completely clean and dry at the time of application and its temperature must be above the dew point to avoid condensation. The moisture content in the wood should not exceed: 16%. Do not apply in direct sunlight. In confined spaces provide adequate ventilation during application and drying.
SUBSEQUENT COAT:
According to specification. Recommended systems are: Hempel Light Primer
The product is used for saturation of absorbent material. For practical purposes, approx. 10 m²/litre is indicated depending on surface roughness, porosity of the surface and application method. When mixing add the curing agent to the base while stirring. Let the mixture react for 15 minutes before use. Only the mixture must be diluted.
No maximum recoating interval demands a flat surface with no surplus of the product. Otherwise sanding is necessary.
