Applications in Practice: Trade Scenarios
For Flooring Installers (On-Site Applicator): High-Movement Timber Installations
The Engineering Challenge
Installing prefinished timber or exotic species like bamboo can lead to cupping or poor adhesion due to substrate moisture. Jobsite installers need an adhesive that performs on critical surfaces without primer delays.
The System-Based Solution with Parquetry PS1300
Parquetry PS1300 bonds securely to timber, cork, stone, and concrete, allowing for movement without delamination. When combined with Primer VBS on slabs, it prevents moisture ingress. Coverage is 600–900 g/m² with a 2–3mm trowel. Open time gives installers flexibility to lay and tap before set-up.
Best Practice Note
In high-humidity installs, pre-condition both substrate and timber to site ambient levels for 48 hours. Always tap timber into adhesive bed to ensure complete wet-out.
For Remedial Contractors: Reflooring Over Screeds
The Engineering Challenge
Old screeds can be uneven, cracked, or patched, making it difficult to install new timber floors without failures or gaps.
The System-Based Solution with Parquetry PS1300
Level subfloors with at least 3mm cementitious underlayment, then use Parquetry PS1300 directly. Its high grab and film thickness handle minor irregularities and ensure sound adhesion even on patched areas.
Best Practice Note
For winter installations, extend drying times (5–6 weeks for 30mm screed). Store adhesive in temperature-controlled area to ensure spreadability.

Applying Parquetry PS1300: Enhanced Protocols & Best Practices
-
Surface Preparation
Ensure all substrates are clean, dry, and structurally sound. Remove dust, grease, and contaminants. Assess evenness using a 2m straight edge—maximum allowable deviation is 5mm.
Concrete Slabs
Apply Adheseal Primer VBS to block moisture ingress. For freshly poured screeds (30mm), allow 4–6 weeks of drying depending on seasonal temperature.
Plywood or Timber
Ensure sheets are securely fixed. Sand lightly to remove surface coatings. Confirm moisture content is between 7–11%.
Timing: Drying time for slabs: minimum 4 weeks (summer), 5–6 weeks (winter).Pro Tip: Test for moisture with a hygrometer — substrate must not exceed 3% moisture content. -
Adhesive Application
Cut the corner of the sachet and pour adhesive directly onto the prepared floor. Spread using a notched trowel (2mm–3mm) for consistent film thickness.
Standard Method
Use a 2mm V-notch trowel for standard parquet blocks. For strip flooring, a 3mm notch may be more suitable depending on substrate texture.
High-Absorption Method
Apply slightly more adhesive on absorbent surfaces to maintain proper transfer onto the timber underside.
Timing: Open time: up to 60 minutes at 23°C and 50% RH.Pro Tip: Apply adhesive only over areas you can cover within 30–45 minutes to ensure optimal wet bonding. -
Timber Installation
Lay timber flooring directly into the adhesive film while it’s still tacky. Apply even pressure for full contact and use a rubber mallet if required.
Floating Installation
Not suitable — Parquetry PS1300 requires full surface contact with adhesive underlay.
Direct Glue-Down
Lay boards into adhesive, leaving 10–20mm expansion joints around perimeters.
Timing: Floor must remain undisturbed for a minimum of 24 hours. Do not sand for at least 48 hours post-installation.Pro Tip: Check underside transfer of adhesive periodically to ensure full coverage and bond integrity. -
Cleanup & Curing
Clean tools and equipment using xylene or toluene before adhesive cures. After full cure, only mechanical removal is effective.
Wet Cleanup
Use cloth soaked in xylene to wipe tools and spills while adhesive is still uncured.
Post-Cure Removal
Cured adhesive must be scraped or mechanically removed. Avoid excessive force on installed flooring.
Timing: Cure rate: approx. 3.5mm/24hr at 23°C and 50% RH. Shelf life: 9 months (unopened, cool dry storage).Pro Tip: Label open containers with date and reseal tightly to extend usability between applications.
