WATERPROOFINGCEMENTSHydroguard One - KRAFT Paints

Cement mortar system for waterproofing

KRAFT HYDROGUARD ONE is a multifunctional waterproof, cement-based, heavy-duty masonry mortar which stops water penetration and prevents water damage while protecting concrete and other masonry surfaces subject to flexural strain. It is applied to both vertical and horizontal surfaces of buildings. It is available in white and grey and it provides more water-proof protection that paint-type coatings. Due to its unique composition, it can be used as one component waterproofing system for the protection of concrete surfaces subject to positive pressure or two component flexible waterproofing system (KRAFT HYDROGUARD FLEX or KRAFT HYDROGU ARD ELASTIC-see relevant TDS). It also presents very good adhesion to the metal substrate as well as to EPS, XPS thermal insulating panels resulting the possibility to combine thermal insulation and waterproofing of surfaces. It meets the requirements defined by ΕΝ 1504-2 for surface protection coating system. It has been tested and it is approved for contact with potable water according to C.M.N. Υ2/2600/2001.

SURFACE PREPARATION
To ensure proper adhesion, the surface must be dry, clean and free of dust, fat, salt, rust, loose paint, and residues, blistered paint, etc. Damaged, delaminated or weak concrete must be repaired using KRAFT STRONG REPAIR 84.
» Before applying the mixture the substrate must be wetted with water by spraying.

APPLICATION INSTRUCTIONS
» KRAFT HYDROGUARD ONE can be mixed with a low-speed electric drill mixer. Pour water into a suitable mixing container and add Comp. A slowly while mixing. Mix thoroughly at least for 3-4 minutes, until the proper lump-free consistency is reached.
» Do not add any additional water or other ingredients.
» Each packaging unit must be entirely mixed, to avoid faulty particle size distribution of aggregates contained in the powder component.
» KRAFT HYDROGUARD ONE can be applied by brush, roller or trowel in two coats crosswise to maximum of thickness of 1mm per coat where waterproofing is available.
» As an adhesive to EPS and XPS panels, KRAFT HYDROGUARD ONE is spread with a trowel on the thermal insulating boards. The boards are pressed firmly on the substrate in order to ensure uniform contact of the adhesive. The final surface must be completely leveled.
» Over the whole surface of the thermal insulating boards and in highly stressed areas a special alkali-resistant glass fiber net HYDROGUARDNET (70-80 g/m²) shall be placed into the first fresh mortar layer. It shall be well trimmed and fully embedded into the mortar avoiding the formation of voids in the coating.
» Potlife: 45min at 25o
» Dry to recoat: 2-5 hours in favorable weather conditions.
» Clean all tools and application equipment with water immediately after use. Hardened material can only be mechanically removed.
» Stir well before use and during application.
» Do not apply at temperatures below 10oC and above 35oC as well as at relative humidity levels above 80%.
» Do not apply if rain is imminent.
» Avoid application in direct sunlight and/or strong wind.

STORAGE

» Stored for 12 months by the production date in its closed and sealed packages, in dry and cool condition preferably on pallets.
