Preparation
Do not use WALL7 below a temperature of 6°C.
Always protect the boarding material with a release agent, e.g. plastic foil as this facilitates the disassembling afterwards.
Surface
- A cement-based surface needs to be at least 21 days old.
- Surface must be structurally clean and sound. Remove all dirt, grease, loosened parts, etc. prior to application.
- When applied on epoxy mortar or epoxy paint, which is older than 7 days, it first needs to be etched chemically with a cloth drenched in acetone or methylethylketon or by mechanical roughening.
- The surface should be dry.
Mixing and application
- Add the complete content of the hardener component B to the total quantity of pre-dosed mortar (component A) in the plastic pail. Mix the two components thoroughly with a low speed mixer for at least 2 minutes until a homogeneous mass is obtained.
- NEVER add water, concrete or other products!
- The first layer has to be thin and well pressed into the surface. A next layer of 3 to 4 centimetres can be applied immediately. Once the 1st layer is hardened, layers of 3 to 4 centimetres can be applied unlimitedly. Make sure that the previous layer is completely dry before adding another one.
- The prepared mortar can be dispersed and levelled on the surface with a trowel.
- Working time after mixture: ca. 40 minutes at 16°C
- Hardening times at 16°C
(*): After ca. 24 hours practicable.
After ca. 72 hours fully mechanical chargeable
After 7 days chemical resistant
(*) Lower temperatures implicate longer hardening times.
Higher temperatures reduce the hardening times.
- Consumption: ca. 1,7 kg/m²/mm
- Material (trowel, mixer…) can be cleaned with acetone or methylethylketone.
Finishing
- A trowel moistened with TEC7 Cleaner facilitates the spreading of the epoxy mortar.
- WALL7 can be painted within 7 days after the application with most common paints.
- WALL7 allows the following processes: rubbing, grinding, drilling, bonding, anchoring, nailing, etc.
