Application

Surfaces

Batts of mineral wool or EPS 80 F with a reinforced render coat of Alfix DuraPuds 810. Allow base coat to dry for at least min. 48 hours.
Cement-based boards, such as KnaufDanogips Aquapanel Outdoor or Fermacell Powerpanel HD with reinforced render coat, such as Alfix DuraPuds 710 or Alfix DuraPuds 810. Allow base coat to dry for at least min. 48 hours.
Concrete, older than 14 days, max. 90% RF.
Light weight concrete, max. 8% moisture content, with reinforced render coat, such as Alfix DuraPuds 810. Allow base coat to dry for at least min. 48 hours.
For further details, please contact our Service Technical Department.

Surface preparation

The surface should be structurally sound, even, free from dust, mortar residues, salts, algae, fungus, and other contaminants. Prime highly absorbent substrates with Alfix PlaneMixPrimer diluted 1:6 with clean water.
Alternatively, surfaces should be primed with Alfix DuraDec 8000 SR paint diluted with water in the ratio 3:1.
Obtain the best possible coverage by using the same colour as the subsequent render. Sand away small edges and other irregularities.
Levelling of uneven surfaces and small cavities and can be made using Alfix DuraPuds 710 or Alfix DuraPuds 810.

How to use

Prior to use, remix rendering compound with mixing paddle and drill at low speed. For a smoother consistency, add water up to max. 5%. Apply Alfix DuraPuds 800 SR to the surface in a thickness corresponding to grain size using steel trowel.
Work the surface immediately with a hard plastic trowel/float until an even texture and coat thickness is obtained. Keep float permanently clean from surplus render. To avoid visible lines of colour differences, it is recommended to finish each wall in one ongoing work process.

Note!
Dark colours are particularly receptive to impacts caused by weather conditions during work as well as surface texture and suction. These on site conditions may result in variations in final appearance and colour differences. Hence, in case of dark and intense colours, it is of significant importance to ensure a uniform surface texture and suction. Prepare and organize the job in order to finish each wall in one
unbroken process and protect against climatic impacts during work and until completely dried.

Tinted facade render
To ensure colour uniformity, tinted render should preferably be of same production batch or be thoroughly mixed together before use. Tinted render is non-returnable.

Exterior work with adhesive render should only take place in dry weather at temperatures between +5ºC and +25ºC. Avoid direct sunlight.
If rainy weather or temperatures below +5ºC are forecast, cover facades.
Avoid exterior rendering during the winter season.

Cleaning

Clean any render residues from tools with water before the material starts to set.
