APPLICATION OF CERESIT RS 88

Apply the product at the right thickness using the mortar. Avoid quick drying and direct exposure to sunlight. At low temperatures, the workability and the drying time will increase. In order to apply in thicknesses higher than 10 mm, add 30% sand (7.5 kg/bag of RS 88) with a grain of < 4 mm. No additional water is required when adding sand.
