Pecko Quartz Pool Plaster

Technical Data Sheet & Method Statement (TDS / MTD)

Product Type: Cementitious quartz-based swimming pool finish
Packaging: 40 kg bags
Application: Hand-applied

1. Product Description

Pecko Quartz Pool Plaster is a premium, factory-blended, quartz-based swimming pool finish engineered to deliver superior colour consistency, durability, and a refined surface texture.

Unlike traditional marbelite systems that rely on on-site bulk mixing to compensate for material variability, Pecko Quartz Pool Plaster is manufactured under controlled conditions to ensure consistent colour and performance from bag to bag.

2. Recommended Uses

  • Residential swimming pools
  • Commercial and hospitality pools
  • New concrete pool shells
  • Pool renovations and replasters

3. Substrate Requirements & Preparation

  • Concrete shell must be structurally sound
  • Minimum concrete curing period: 28 days
  • Surface must be clean, roughened, and free of dust, oils, laitance, algae, paint, or curing compounds

Preparation steps:

  • Mechanically remove all loose or contaminated material
  • Repair cracks, voids, and honeycombing using suitable repair mortar
  • Thoroughly clean and rinse the surface
  • Pre-wet substrate to SSD (Saturated Surface Dry) condition
Primer: No primer is required when Pecko Quartz Pool Plaster is applied to a properly prepared concrete substrate. A cementitious bonding slurry may be used at the installer’s discretion on dense or previously plastered surfaces. Acrylic, PVA, or film-forming primers are not recommended.

4. Factory Consistency & Batch Control

Pecko Quartz Pool Plaster is factory dry-blended in controlled pan mixers to ensure uniform dispersion of cement, quartz aggregates, fillers, and pigments.

Because colour consistency is engineered at manufacturing level, bulk dry mixing of all bags on site is not required. Each bag may be mixed individually provided water content and mixing time are controlled.

Dry dumping and shovel mixing on the pool floor is not suitable for quartz-based plaster systems.

5. Mixing Methods

5.1 Preferred Method – Mechanical Mixing

  • Forced-action mixer, pan mixer, or heavy-duty paddle mixer
  • Clean potable water

Water requirement: 6.5 – 7.5 litres per 40 kg bag

  • Add approximately 80% of required water to the mixer
  • Add one full 40 kg bag
  • Mix for 3–5 minutes until homogeneous
  • Add remaining water gradually to achieve workable consistency
  • Allow mix to rest for 1 minute, then remix briefly

Pecko Quartz Pool Plaster is designed for standard pool plaster application thicknesses of approximately 6–8 mm and does not require mix adjustments for variations in applied thickness.

5.2 Approved Manual Mixing Method (When No Mixer Is Available)

Where mechanical mixing is not available, Pecko Quartz Pool Plaster may be mixed manually using a controlled drum or tub method.

  • Use a clean 200–250 L drum or mixing tub
  • Measure water accurately (6.5–7.5 L per bag)
  • Add material gradually while mixing continuously
  • Mix aggressively for 4–6 minutes, scraping sides and bottom
  • One full bag per batch only
Floor dumping, shovel mixing, or adding water directly on the pool shell is not permitted.

6. Time-Efficient Mixing Workflow (4-Person Crew)

  • Mixer Operator: Controls water measurement and mixing consistency
  • Material Handler: Loads bags, manages buckets, keeps area clean
  • Lead Plasterer: Applies plaster to walls and floor
  • Assistant Plasterer: Supports application, detailing, and finishing

Mix one bag at a time, supplying fresh material every 6–8 minutes to maintain continuous application and consistent finish quality.

7. Application

  • Hand apply using steel pool trowels
  • Apply continuously to avoid cold joints
  • Typical thickness: 6–8 mm (thicker on steps and coves)
  • Avoid overworking the surface
  • Do not add water during finishing

8. Product Coverage

Coverage: Approximately 2.0 – 2.5 m² per 40 kg bag, based on an average applied thickness of 6–8 mm.

Actual coverage may vary depending on pool geometry, surface condition, detailing (steps, benches, coves), and application technique.

9. Curing & Filling

  • Minimum dry cure before filling: 24 hours
  • Darker colours: 36–48 hours recommended
  • Filling must be continuous and uninterrupted

Misting Guidance

  • Use fine mist only (not spray)
  • 5–10 minutes, 2–3 times per day in hot, dry, or windy conditions
  • Misting line positioned 300–600 mm above surface

10. Initial Water Start-Up

  • No brushing for first 24 hours after filling
  • Light brushing thereafter using nylon brush only
  • Avoid aggressive chemical adjustments for first 72 hours
  • Do not add acid directly into the pool

11. Appearance Disclaimer

Colour appearance is influenced by water depth, lighting conditions, pool design, and water chemistry.

Images are representative only. Final pool colour may vary.

12. Limitations

Performance depends on correct surface preparation, mixing, application, curing, and water start-up. Failure to follow these guidelines may affect appearance and durability.
