Kölner Rapid is specifically developed for stone mason requirements.The adhesive is applied undiluted in two layers with a brush. After approximately 15 minutes of drying (depending on the thickness of the Rapid layer, temperature, and relative humidity), you can either apply a second layer of Rapid or you can start gilding. Beware that the Rapid layer must be completely dry before gilding. After that, you have three days open time to make a high-quality gilding.If it concerns a strongly absorbing surface, several layers of adhesive can be applied. Make sure that the layer is always completely dry before painting a next layer.Sealing of the stone is then no longer necessary. Working with Kölner Rapid is comfortable and safe, and will quickly feel natural. Especially work outdoors can be done fast, yet with high quality, for example on site or/and at the cemetery.For large surfaces, Kölner Rapid can be sprayed as well after diluting it with no more than 8 % distilled water. A low pressure sprayer with a nozzle size of 1 – 1,5 mm is recommended.Kölner Rapid can also be applied with a brush.
