Frequently asked questions
Common questions from surveyors, procurement teams and asset managers.
How long do MMA balcony systems last?+
A correctly specified and installed MMA decorative flake system on a residential balcony typically lasts 15–20+ years with routine maintenance.
Are the systems fully waterproof?+
Yes. The systems we install are designed as bonded liquid waterproofing membranes — fleece-reinforced at all upstands, thresholds, drainage outlets and balustrade fixings — so the deck itself, not just the topcoat, is waterproof.
Can residents still access the building during works?+
Yes. We deliver in phases with temporary walkways, hazard tape and clear resident communication so access is maintained throughout the works.
How long before a balcony or walkway can be reopened?+
MMA systems can be reopened to foot traffic in 60–90 minutes from final application, even in cold weather. PU and polyaspartic systems typically require 12–24 hours.
How slip-resistant are the finished systems?+
Anti-slip broadcast systems are specified to achieve at least 36 Pendulum Test Value (PTV) in wet conditions, in line with HSE guidance. Stair nosings and ramps typically target 55+ PTV.
What maintenance do the systems need?+
Sweep weekly, remove debris from drainage outlets, pressure-clean at low pressure with a pH-neutral cleaner and carry out an annual visual inspection of upstands, joints and fixings.
Can damaged areas be repaired later?+
Yes — MMA and PU systems are compatible with themselves, so localised damage can be cut out and reinstated seamlessly.
What is the typical installation programme?+
A single-balcony refurbishment is typically completed in one working day including preparation. A full-block phased programme is agreed with the client and communicated to residents in advance.
What colour options are available?+
Standard MMA flake blends are available in greys, charcoals and stone tones. Bespoke colour blends are available on larger projects.
What warranty is provided?+
F Wilding Ltd waterproofing installations carry a warranty from 5 years as standard. Longer manufacturer-backed system warranties are available on request.
Are the systems suitable for London councils and TMOs?+
Yes — we work extensively with London borough councils, tenant management organisations and housing associations across Greater London.
Can you deliver Section 20 works under leaseholder consultation?+
Yes. We regularly deliver refurbishment works that fall under Section 20 consultation and can provide the specification, cost breakdown and scope required for the notice.
Do you handle Section 20 leaseholder communication?+
The formal Section 20 process sits with the freeholder or managing agent, but we provide the technical documentation required and can attend leaseholder briefings.
What accreditations do you hold?+
CSCS operatives, SSSTS/SMSTS supervision, manufacturer-approved installer status and full public liability insurance.
Do you provide RAMS and pre-construction information?+
Yes — task-specific RAMS are issued pre-start and reviewed with the principal contractor or client PM.
Can you work around night-time or weekend restrictions?+
Yes. Where noise or access constraints require it, we deliver evening, night and weekend shifts.
How do you handle unforeseen concrete repairs?+
Concrete repairs are quoted at agreed unit rates and re-measured against the actual scope discovered during preparation.
Can you refresh existing MMA or PU systems without a full strip?+
Yes — where the base system is bonded and structurally sound, we can grind, prime and overlay to extend the life of the deck by another 10+ years.
Do you offer whole-block asset surveys?+
Yes. We survey communal areas across a whole estate or portfolio and provide a prioritised report with indicative costs for phased delivery.
How quickly can you mobilise?+
For most housing schemes we mobilise within 2–4 weeks of order, subject to programme constraints and resident notification requirements.
