Substrate

Properties/tests

• For assessing the plaster primer, VOB/C DIN 18350, Section 3, DIN EN 13914-1/13914-2 as well as the plaster standard DIN 18550-1/18550-2 should be observed.
• The substrate must be load-bearing, clean and free of adhesion-reducing residues.

Pretreatment

• Old plaster must be removed at least 80 to 100 cm above the visible or adjacent damaged zone up to the masonry.
• Crumbly masonry joints are to be scraped out approx. 2 - 3 cm deep.
• Damaged stones must be replaced.
• Non-load-bearing coatings must be completely removed.
• Clean masonry thoroughly and remove dust.
• Highly absorbent substrates should be wetted in good time, days before if need be.

Processing

Processing

• Can be applied by hand and with standard plastering machines.
• When using plastering machines, no additional equipment (e.g. additional mixer or air-entraining screw jacket) needs to be used.
• When using a machine: Adjust the water supply to a workable consistency.
• When mixing manually, first place the quantity of water specified in the technical data in a clean container and then sprinkle in dry mortar. Use clean tap water.
• Mix the material with a suitable agitator until homogeneous and lump-free, allow briefly to rest and then stir again, adding more water if necessary, and adjust the consistency to a workable consistency.
• Do not mix with other products and/or foreign substances.
• Spray on approx. 50 – 60 % of the pre-spray plaster in a rough, net-like, semi-covering coat.

Cleaning the tools

• Clean all tools and equipment with water immediately after use.

Notes

• Maintain a processing temperature of +5 °C to +30 °C.
• Mortar that has already hardened cannot be diluted with additional water, re-mixed and further processed.
• In unfavorable weather conditions (e.g. driving rain, strong sun and/or wind, frost), suitable protective measures must be taken, especially for freshly coated surfaces.
• Further coating with INTRASIT restoration plasters in accordance with WTA 2-9. Please refer to the technical data sheet of the selected product or our project-related restoration proposal.
• Carefully cover adjacent surfaces and components (e.g. windows, window sills, etc.). Wash off any soiling immediately with water.
• Construction waste close to the renovation site must be removed daily to prevent salt migration.
