Sector-specific challenges and structural wear

A domestic sanding schedule rarely suits a building with deliveries at six, staff arriving at eight and customers through the door all day. Office chair castors, retail grit, restaurant cleaning chemicals and gym traffic wear coatings in different ways. An off-the-shelf polish may briefly add shine, but it will not re-bond loose parquet or restore protection where the seal has worn through.

We assess private and serviced offices, coworking spaces, shops, boutiques and showrooms, shopping-centre units, cafés, pubs and restaurants. The same practical checks matter in workshops, factories, storage and distribution premises, gyms, cinemas, studios, hotels, clinics, schools, colleges, universities and places of worship, although some of those sites may have timber only in selected rooms or circulation areas.

• Open joints: gaps collect grit and food debris, making hygienic cleaning harder and damaging board edges under traffic.
• Loose blocks or raised boards: movement can create a trip point; coating over it does not fix the bond or the substrate.
• Moisture ingress: leaking entrances, wet cleaning and damp subfloors can cause cupping, staining or adhesive failure.
• Slip risk: a glossy appearance says little about performance when wet. Where required, specify pendulum testing of the finished route under BS EN 16165:2021, Annex C.
• Repeated chemical attack: unsuitable detergents can dull or soften a finish, especially around bars, treatment rooms and takeaway counters.

How we plan a commercial timber floor restoration

Step 1: Subfloor audit and moisture testing

We inspect fixings, board thickness, parquet movement, old repairs and the likely depth of the existing finish. A hygrometer check on a suspect screed and moisture readings from the timber help establish whether sanding and re-bonding can proceed. If there is an active moisture source, that is dealt with before a new seal goes down.

Step 2: Timber repairs, re-bonding and resin gap-filling

Loose parquet is lifted and re-bonded with a compatible silane-based flexible parquet adhesive where the substrate and product specification allow it. We replace unsound timber with a matching species and grain where practical; teak, oak and pitch pine should not be treated as interchangeable. For stable, narrow joints, a compatible resin-slurry gap fill can close dirt traps; wide or moving gaps usually need timber slivers or a different repair.

Step 3: HEPA dust-controlled sanding and surface preparation

A Lägler Hummel belt sander levels the main field, with edge and detail machines used at skirtings, doorways and fixed joinery. We connect suitable equipment to HEPA H14 dust extraction, isolate adjacent rooms and protect ventilation intakes. Dust control reduces migration; it does not remove the need to clear the work area and manage access.

Step 4: High-traffic finishes

For busy circulation routes, a specified 2K waterborne polyurethane lacquer uses a cross-linking catalyst to improve wear and chemical resistance once fully cured. Hardwax oil can suit rooms where local repairs matter, provided the cleaning regime and maintenance intervals are understood. In entrance or spill-prone areas, we discuss an appropriate anti-slip coating or additive and arrange slip testing where the site risk assessment calls for it.

We review product data sheets, COSHH assessments and the site’s ventilation needs before application. Where indoor air emissions are a priority, we can specify suitable products carrying an EMICODE EC1 Plus rating. Recoat intervals, light foot traffic and full cure are separate milestones: the agreed reopening time comes from the chosen product, temperature, humidity and actual site conditions.

Step 5: Aftercare and maintenance protocols

We hand over a cleaning schedule matched to the finish, including suitable neutral cleaners, entrance matting and when to inspect high-wear lanes. Facilities teams should avoid steam cleaning, standing water and improvised chemical mixes. A planned clean and recoat can often extend the life of a sound lacquer before another full sanding is needed.

Working around an active building

Before mobilisation, we agree deliveries, waste routes, noise limits, fire exits and the point at which each area can return to use. Site-specific risk assessments and method statements (RAMS) set out isolation, dust control, electrical arrangements and access for other trades.

A quote built around the site

Send photographs or a short video for an initial assessment, then arrange a physical survey to check floor area, repairs, moisture, access and finish requirements. The written scope should separate sanding, timber repairs, gap filling, coatings, out-of-hours work and any slip testing. See the floor restoration gallery for examples of finished work and the prices page for published guide rates; a commercial quotation depends on the surveyed floor and programme.

For managed sites, confirm the CSCS cards required for attending operatives and request current commercial liability insurance details before work starts. We can then align the RAMS, delivery arrangements and handover record with your facilities or principal contractor’s requirements.
