  • Application surface should be clean, sound and free from dust.
  • Adhesion barrier materials (oil, dirt, dust, etc.) should be cleaned, cement-mortar residues should be scraped.
  • Gaps and cracks on surface should be repaired with G-REPAIR-1200 or G-REPAIR-800 repair mortars at least 1 day before the application.
  • If needed, surface should be cleaned with water, excess water should be removed.
  • PRIMER-ST primer should be used at least 1 hour before the application to reduce water absorption of the surface and to provide better adhesion.



20 kg HYDRO-G10 powder component is added on 10 kg HYDRO-L10 liquid component by sprinkling.
Mortar is blended by a low speed mixer to ensure that there are no lumps in it. Mortar is rested for 3 minutes to mature and mixed again before application.
Prepared HYDRO-G10 mortar is applied to the corners and joints with a small brush as a thin layer. Waterproofing tape is placed to the corners and joints, then it is embeded in the fresh mortar by gently pressing by the brush.
After taping is finished, HYDRO-G10 mortar is applied as 1 mm on the surface in one direction brush strokes as 1st layer by a roller or brush. If application area is bigger than 5 m², flex THERMMESH-A1 glass-fiber mesh is placed on the mortar while 1st layer mortar surface is still fresh. Mesh is embeded on fresh mortar by gently pressing with a brush or roller. To prevent crack formation, glass-fiber mesh should be placed as endpoints min. 10 cm overlapped. To prevent crack formation at corners and joints, mesh should be applied with a 1 cm overlay on the edge of the waterproofing tape.
After 6 hours from 1st layer application (before surface completely dry), prepared HYDRO-G10 mortar is applied on the entire surface in reverse direction brush strokes with a 1 mm thickness as 2nd layer. If 1st layer surface is dry, it should be humidified before 2nd layer application. During the application, make sure that there is no space, hole or area without mortar at surface. Make sure that every mortar layer covers the application surface completely. After setting time is completed, surface becomes ready for other applications on it. At lightly loaded areas there may not need to apply a coating material on HYDRO-G10. However, in all applications, protecting the product surface from external environmental effects with a coating material application will extend the life of water isolation. If a caoting material will be applied on HYDRO-G10, minimum C2 type tile adhesive should be used for fixing. If a caoting material will not be applied on HYDRO-G10, to improve the surface strength at least 3 layers application is recommended.
Ambient and surface temperature should be between +5 ̊C and +30 ̊ during the application.
Any additional material (such as lime, cement, gypsum etc.) should not be added in to prepared mortar.
Mortar should not be applied on frozen, melting or within 24 hours danger of frost surfaces.
Hardened-set mortar should not be used by adding water and mixing again.
Mortar should not be applied on unsound and loose surfaces.
Surface should be protected from direct sunlight, extreme wind and rain during and after the application.
