Elastomeric resin based, flexible, solvent-free, one component-liquid waterproofing material providing high water impermeability on cementitious surfaces (in 15 kg and 5 kg buckets)




  • HYDRO-LP Liquid Water Isolation Product provides labor & time advantage due to it’s easy preparation and application features.
  • Provides high adhesion, durability and water isolation.
  • Provides less consumption at unit area by it’s special formula.
  • Prevents formation of shrinkage cracks by it’s flexible feature.
  • Provides an economic and ideal waterproofing solution without shrinkage and joints on cementious surfaces.


Applied by a roller or brush to provide a high quality, smooth, nonshrink, flexible and water proofing surface on cementious surfaces (concrete, plaster, screed, etc.) which will be used as wet area (spa, bathroom, kitchen, balcony, terrace, pool, etc.).

  • 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 & 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. HYDRO-LP is ready for use, there is no need a preparation for the product.
It is blended by a low speed mixer or trowel until becomes homogeneous. HYDRO-LP is is firstly applied to the corners and joints with a small brush as a thin layer. Waterproofing tape is placed and embeded on the fresh HYDRO-LP surface at corners and joints by gently pressing with the small brush.
After taping is finished, HYDRO-LP is applied on the entire surface in one direction strokes with a 1 mm thickness as 1st layer by a roller or brush. If application needs higher mechanical strength, flex THERMMESH-A1 mesh is placed on the fresh 1st layer surface. Mesh is embeded on fresh surface by gently pressing with brush or roller. To prevent crack formation at mesh junction point, mesh should be placed as endpoints min.imum 10 cm overlapped. To prevent crack formation at corners, mesh should be applied with 1 cm overlay on the edge of waterproofing tape.
After approx. 6 hours from 1st layer application (when surface is completely dry), HYDRO-LP is applied on the entire surface in reverse direction brush strokes with a 1 mm thickness as 2nd layer. During the application, make sure that there is no space, hole or area without mortar at surface. Make sure that every HYDRO-LP layer covers the application surface completely. After setting time is completed, surface becomes ready for other applications on it.
At non-navigable areas there may not need to apply a coating material on HYDRO-LP. However, in all applications, protecting the product surface from prolonged external environmental effects with a coating material application will extend the life of water isolation. If a caoting material will be applied on HYDRO-LP, minimum C2 type tile adhesive should be used for fixing. HYDRO-LP should be applied at least 2 layers. It is recommended to apply 3 layers in areas requiring high protection.
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.
Mortar should not be applied on unsound and loose surfaces.
If there are lumps in mortar because of mixing, lumps should be taken from mortar, lumped mortar shouldn’t be applied.
Surface should be protected from direct sunlight, extreme wind and rain during and after the application.
