Top 10 Questions for Permastone Installer Interview

1. What are the different types of Permastone finishes and how do they differ?

Permastone offers a range of finishes to cater to different aesthetic preferences and functional requirements:

• Smooth finish: Provides a sleek and polished appearance, often used for interior applications and surfaces that require low maintenance.
• Textured finish: Adds visual interest and slip resistance, suitable for outdoor areas, flooring, and surfaces that need increased grip.
• Exposed aggregate finish: Reveals the natural beauty of the underlying aggregate stones, providing a rugged and decorative surface for exterior applications.
• Integral color finish: Incorporates color pigments into the Permastone mix, allowing for a wide range of color options and a uniform appearance throughout the entire surface.
• Stamped finish: Imprints patterns or textures into the wet Permastone, creating a unique and decorative surface that mimics natural materials like stone, brick, or wood.

2. What are the critical steps involved in preparing a surface for Permastone installation?

Surface Preparation

• Properly clean the surface to remove any dirt, debris, or contaminants that could affect adhesion.
• Ensure the surface is level and smooth, using a screed or leveling compound if necessary.
• Create a roughened surface by sandblasting or grinding to improve bonding between the Permastone and the substrate.
• Apply a primer or bonding agent to enhance adhesion and prevent moisture penetration.

Formwork

• Install formwork to define the edges and shape of the Permastone surface.
• Ensure the formwork is securely anchored and aligns with the desired dimensions.
• Apply a release agent to the formwork to prevent the Permastone from sticking.

3. How do you ensure proper hydration of Permastone during the curing process?

• Moist curing: Cover the Permastone surface with wet burlap or plastic sheeting to maintain moisture levels and prevent rapid drying.
• Water spray: Regularly mist or spray the Permastone surface with water to keep it hydrated.
• Curing compounds: Apply a water-based curing compound to the surface to form a membrane that retains moisture and reduces evaporation.
• Proper timing: Allow sufficient curing time, typically 7-14 days, depending on environmental conditions and the thickness of the Permastone.

4. What are the common causes of cracking in Permastone and how can they be prevented?

• Excessive shrinkage: Improper curing or rapid drying can lead to shrinkage and cracking.
• Movement in the substrate: Structural movement or settling can cause stress and cracks in the Permastone.
• Improper reinforcement: Inadequate reinforcement, such as insufficient fiber or mesh, can weaken the Permastone and make it more susceptible to cracking.
• Thermal expansion and contraction: Changes in temperature can cause expansion and contraction, leading to cracking if the surface is not properly designed for movement.
• Chemical reactions: Exposure to certain chemicals or salts can deteriorate the Permastone and cause cracking.

5. Describe the steps involved in repairing a damaged Permastone surface.

• Remove damaged material: Chip away or grind down the damaged area to expose the sound Permastone.
• Clean and prepare the surface: Remove any loose debris or contaminants, and roughen the surface to improve bonding.
• Apply bonding agent: Brush or trowel a bonding agent onto the prepared surface.
• Mix and apply repair material: Prepare the Permastone repair material according to the manufacturer’s instructions and apply it to the damaged area.
• Finish and cure: Smooth the repair material and allow it to cure properly, following the same hydration techniques used during the initial installation.

6. What safety precautions should be taken when working with Permastone?

• Wear proper protective gear: Gloves, safety glasses, and a dust mask to protect against dust and debris.
• Handle chemicals carefully: Use appropriate gloves and follow manufacturer’s instructions when handling primers, bonding agents, and curing compounds.
• Avoid inhalation of dust: Wear a dust mask and keep the work area well-ventilated.
• Be aware of electrical hazards: Use caution when operating power tools and ensure proper grounding.
• Follow manufacturer’s guidelines: Always read and follow the manufacturer’s safety instructions for Permastone products.

7. How do you determine the appropriate thickness for a Permastone installation?

• Intended use: Consider the load-bearing requirements and traffic conditions for the specific application.
• Substrate condition: Evaluate the strength and stability of the underlying substrate.
• Spanning distance: Determine the distance between supports or reinforcement to ensure adequate structural integrity.
• Environmental factors: Account for potential temperature fluctuations, moisture exposure, and chemical resistance.
• Industry standards: Refer to manufacturer’s recommendations and industry guidelines for minimum thickness requirements.

8. What techniques can be used to achieve a seamless finish when joining multiple Permastone sections?

• Staggered joints: Overlap adjacent sections slightly and stagger the joints to minimize visible lines.
• Feather edging: Grind or sand the edges of the sections to create a smooth transition.
• Color matching: Use pigments or stains to blend the colors of the sections for a uniform appearance.
• Grinding and polishing: Smooth out the joints using a grinder or polisher to minimize any irregularities.
• Sealants: Apply a clear sealant to the joints to prevent moisture penetration and enhance the overall finish.

9. How do you ensure proper drainage when installing Permastone outdoors?

• Slope the surface: Create a gradual slope to direct water away from the surface.
• Install drainage channels: Integrate channels or grooves into the Permastone to facilitate water flow.
• Provide weep holes: Allow water to escape from the substrate through strategically placed weep holes.
• Use permeable materials: Consider using permeable underlayments or bedding materials to allow water to drain through the system.
• Maintain proper drainage: Regularly clean gutters and drains to prevent blockages that could lead to water buildup.

10. What are the advantages of using Permastone over traditional concrete?

• Superior durability: Permastone is highly resistant to wear, impact, and chemicals, making it ideal for high-traffic areas.
• Aesthetic versatility: Offers a wide range of colors, textures, and finishes, allowing for customized designs and architectural expression.
• Cost-effective: While the initial installation cost may be slightly higher than traditional concrete, Permastone’s durability and low maintenance requirements provide long-term savings.
• Easy maintenance: Requires minimal maintenance, such as occasional cleaning and resealing, to maintain its aesthetic appeal.
• Environmentally friendly: Permastone is a sustainable material made from recycled glass and aggregates, reducing the environmental impact of construction.
