Kronalux® 2K Pool Sealer 787

Substrate preparation:

The prerequisite for durability is a load-bearing, grease-free, dry substrate that has been thoroughly cleaned of dirt and dust deposits.
For swimming pools, the outer walls must be well insulated against ground moisture and groundwater. Lack of or inadequate insulation is usually the cause of blistering and peeling paint.

Existing GRP pools must be free of damage and watertight. Smaller damaged areas can be repaired with 415 2K - PE - Fibre Filler. Before coating, the pool must be cleaned with Jaeger Special Cleaner 80 and sanded with P80 grain.
Concrete must be well cured before starting the painting work, i.e. it should be at least 4-6 weeks old. Concrete must not be smoothed with a steel trowel, but must be scraped off with a felt disc to obtain a surface with good grip. Cement paste and sinter layers must be removed by sandblasting. Concrete surfaces must be primed twice with Kronalit Special Priming Resin 864.
For iron surfaces in swimming pools - such as access ladders - we recommend priming 2 x with Kronalit® 819 (sandblasting if necessary) on a well derusted, load-bearing substrate.

Filling:

Use 2K - PE - Fibre Filler 415 for repair work on GRP pools.

Paint structure:

Stir the material well before application, mix both components homogeneously by machine and repot!
Apply 2 - 3 x 786 GRP Pool Paint by roller or spraying. If necessary, dilute with Special Thinner 97 up to max. 10 %.
Apply 1 x 787 2C Pool Sealer by roller or spraying.

Revisability:

Can be recoated after 12 hours in dry weather, otherwise longer.

Repair work (old swimming pools):  

Overhaul coatings require particularly thorough cleaning of the substrate to remove algae, dirt and deposits. Thoroughly remove limescale deposits and algae growth with commercially available decalcifiers. Rinse thoroughly with water! Greasy deposits can be removed with Jaeger Special Cleaner 80. Remove poorly adhering coatings.

Maintenance and winterisation of swimming pools:

Remove greasy edges with alkaline cleaners, lime deposits with decalcifier; rinse thoroughly with water! Larger pools should preferably be filled during the winter; use straw, brushwood or reed bundles to protect the pool walls against ice pressure. In case of heavy frost, the ice cover along the pool edge should be sawn open from time to time in sufficient width. Smaller pools are best overwintered empty.

Processing conditions:

During the entire application and drying time, the material, substrate and air temperature must not be below 8 °C and not above 30 °C. Do not apply in direct sunlight, as this may lead to rapid drying and blistering of the coating film. The air humidity should be between 30% and 75% during the entire application time.

Accidents due to slipping in walk-through pools, children's paddling pools, on steps, etc. are avoided if dry quartz sand 0.1 - 0.4 mm is sprinkled into the first coat.
