Keim Purkristalat is a two component mineral paint system for coatings of highest durability and excellent colour brilliance. Keim Purkristalat consists of a fine colour powder component (Purkristalat-powder) and a liquid waterglass component (Keim Fixativ) as binder.
Keim Purkristalat should not be used onto previously painted surfaces. If there are existing coatings these should be stripped prior to use of the Keim Purkristalat system.
Highly absorbing or sanding substrates should be pretreated with Keim Fixativ, diluted 1:1 with water.
All loose, flaking and unstable material must be identified and then thoroughly removed, all surfaces must be thoroughly washed down with clean cold water to remove all surface dirt and dust. When all surfaces are clean, sound, wind dry, dust free and free from all surface contaminants, decoration using Keim Purkristalat may proceed.
Soak 5kg of Keim Purkristalat powder in 4lt Keim Fixativ and stir until homogeneity (this mixture equates to approximately 10 kg of ready to use paint). Better homogeneity and higher yield (lower consumption) is achieved from preparing the material the day before.
First Coat :
For the first coat, this basic mix is to be thinned with 2 to 6lt of Keim Fixativ depending on the absorption of the substrate. The first coat is to be brush applied. Keim Purkristalat should be applied keeping a wet edge, preferably by brush or low pressure spraying.
If necessary, the filling additive Keim Kristall Felsit may be added.
Second Coat :
For the second coat the undiluted basic mix should be applied in a like manner.
Ambient and substrate temperature above 5°C and below 30°C. Do not apply in direct sunlight or onto sun-heated surfaces, nor if it is raining or if there is an immediate likelihood of rain.
