SP-G (SAP) / Renovation Plaster

Details:

• Application: For damp and salt-saturated vertical surfaces.
• Porosity: High air pore content.
• Base: Cement-based.
• Durability: Resistant to frost and moisture.
• Use: Suitable for both exterior and interior applications.

Preparation:

1. Surface Removal: Remove old plaster at least 100 cm above the visible salt efflorescence line.
2. Joint Cleaning: Clean mortar joints to a depth of at least 20 mm and fill them with SAKRET SP-G (SAP).
3. Standards Compliance: Prepare surfaces according to WTA guidelines.
4. Coating Removal: Mechanically remove coatings that negatively affect adhesion using pressure washers or sandblasting.
5. Primer: Treat the surface with SAKRET VSM adhesion agent before applying SAKRET SP-G.

Application:

• Shallow Joints: If mortar joints are shallow, they can be filled while applying the first coat of plaster (up to 10 mm thickness).
• Moisture Control: Identify and eliminate the source of moisture migration for maximum effectiveness.
• Minimize Handling: Mechanically process fresh mortar as little as possible to maintain air pore quantity.
• Drying Time: Allow the renovation plaster to dry for at least 4 hours but not longer than 3 days before applying a second coat.
• Texturing: Texturing should be done using a trowel, just like traditional plaster.
• Surface Condition: Do not begin texturing if the surface is still wet, as this can impair the plaster's performance.
• Leveling: For a smooth finish, it is recommended to use SAKRET SFP.
• Protection: Protect freshly applied material from strong winds, direct sunlight, rain, and freezing temperatures.
• Re-mixing: Do not dilute set material with water; instead, re-mix it.
