Jotun Tough Shield Primer For Exterior 20L

Description
• It offers good adhesion between wall surface and topcoat to deliver a good finish and lasting protection, enhancing the appearance of topcoat.
   - Good Adhesion
   - Alkali Resistant
• Tough Shield Primer establishes a durable base for the Tough Shield paint system, enhancing the appearance and performance of the topcoat.

Specifications
• Packaging size: 20L
• Solids by volume: 35 ± 2 volume%
Application data
• Remarks: Handle with care. Stir well before use.
• Application equipment / methods: By brush, roller, airless spray or conventional spray.
• Guiding data for airless spray:
   - Nozzle tip 0.021–0.027"
   - Spray angle degrees 65–80°
   - Pressure at nozzle 140 - 190 kg/cm² (2100 psi)
• Spreading rate per coat
   - Theoretical 11.6 m²/l - 8.8 m²/l
   - Spreading rate depends on film thickness applied, type of texture, surface porosity, imperfections, temperature, wastage during painting etc.
• Recommended film thickness per coat
   - Wet 85 µm - 114 µm
   - Dry 30 µm - 40 µm
   - Film thickness will vary and is calculated as average.
• Thinner: Water
• Dilution: The product is ready to use after proper stirring. If thinning is required, water may be added up to a maximum of 5%.
• Conditions during application
The temperature of the substrate should be minimum 10 °C and at least 3 °C above the dew point of the air, measured in the vicinity of the substrate. Good ventilation is usually required in confined areas to ensure proper drying.
• Drying times
Drying times are generally related to air circulation, temperature, film thickness and number of coats, and will be affected correspondingly. The figures given in the table are typical with:
   - Good ventilation (Outdoor exposure or free circulation of air)
Typical film thickness
   - One coat on top of inert substrate
   - The given data must be considered as guidelines only. The actual drying time and time before recoating may be shorter or longer, depending on the ambient temperature, film thickness, ventilation, humidity, underlying paint system, requirement for early handling and mechanical strength etc.
1. Recommended data given is, for recoating with the same generic type of paint.
2. In case of multi-coat application, drying times will be influenced by the number and sequence and by the total thickness of previous coats applied.
3. The surface should be dry and free from any contamination prior to application of the subsequent coat.
The drying time is measured by stated values:
   - Relative Humidity (RH): 50 %
   - Substrate temperature: 10 °C
      - Surface (touch) dry: 2 h
      - Hard dry: 8 h
      - Dry to over coat, minimum: 4 h
   - Substrate temperature: 23 °C
      - Surface (touch) dry: 1 h
      - Hard dry: 6 h
      - Dry to over coat, minimum: 2 h
   - Substrate temperature: 40 °C
      - Surface (touch) dry: 0.5 h
      - Hard dry: 4 h
      - Dry to over coat, minimum: 1 h

Features & Benefits
• Good Adhesion - Provides good adhesion between wall surface and topcoat to deliver a good finish and lasting protection.
• Alkali Resistant - Resists alkali attack that causes discolouration and improves the appearance of topcoat.
• Formulated Without Harmful Chemicals - Free from harmful chemicals such as APEO, formaldehyde, heavy metals and has low volatile organic compound (VOC).

Type
Jotun Tough Shield Primer is an acrylic water-based sealer that acts as a good foundation for topcoat. It is easy to use and improves both the appearance and performance of topcoat.

Recommended use
For exterior application, suitable for new buildings or repainting.

Substrate
On concrete, masonry, plaster, brick work and soft board surfaces.

Directions for use
Surface preparation
• The substrate must be sound, clean, dry and free from dust, oil, grease, laitance etc. All traces of form release agents/curing agents must be removed. A light sanding with suitable abrasive material is recommended before application. Any resulting dust/loose particles must be removed.
Recommended paint system
• Primer: Jotun Tough Shield Primer:1 coat
• Topcoat: Jotun Tough Shield Max (Matt):2 coats
• Storage
The product must be stored in accordance with national regulations. Keep the containers in a dry, cool, well ventilated space and away from sources of heat and ignition. Containers must be kept tightly closed. Handle with care.
