Surface prep expertise for UK contractors
A folder of cards is not a competence system. This guide sets out the evidence a UK blasting crew should be able to produce before mobilisation, and how a one-page verification matrix can help principal contractors and facilities managers confirm who is genuinely authorised for the nozzle, the pot and the helmet.
Blast-and-coat works depend on clean interfaces between scaffolding, masking, blasting, coating and inspection. This article sets out a practical handover protocol for defining trade boundaries, recording acceptance and preventing avoidable rework on UK sites.
Abrasive does not distinguish between a substrate due for renewal and a sealed unit that must survive the works. This guide sets out a practical protection protocol for glazing, composite cladding, seals, sensors and pipework on occupied or partially live refurbishment sites, from the pre-blast survey to post-blast inspection.
Lead-based paint on UK steelwork and cladding can turn abrasive blasting into a dust and waste management problem long before the first pass. This guide sets out a practical decision record: sampling and laboratory confirmation, COSHH and Control of Lead at Work duties, containment and RPE choices, waste classification and the client communication trail.
Breathing air for blast helmets is an engineered safety system, not a hose trailing from the site compressor. This guide sets out how UK contractors can site, filter, route and record helmet air supply so that cleanliness, temperature and reliability are demonstrated rather than assumed.
A specified profile is a measurable outcome, not a matter of visual judgement. This guide sets out how UK contractors can verify blast roughness with comparators, replica tape and digital gauges, and how to record readings that withstand scrutiny when coating performance is questioned.
Legacy paints, bitumens and mastics can conceal asbestos, and abrasive blasting can turn that hidden hazard into a site-wide contamination issue. This protocol sets out the pre-start checks, legal decision points, containment measures and waste records UK contractors should have in place before work begins.
Fixed blast rooms fail quietly: a filter loads, a duct accumulates dust, a recovery valve wears, and the first obvious sign is a failed LEV test or a lost shift. This guide sets out a monthly, quarterly and annual maintenance calendar for extraction, ducting, recovery, lighting and door seals, with the UK COSHH records inspectors expect to see.
Abrasive recycling is often presented as an automatic saving, but the true comparison is cost per compliant square metre, not cost per tonne. This guide sets out how UK contractors can test media quality, account for contamination and downtime, and recognise when fresh media is the cheaper and safer choice.
Cold weather does not stop blasting, but it relocates the failure points: compressed-air lines, moisture traps, abrasive feed, hoses and site access all behave differently. This guide sets out a practical winter regime for UK contractors, from pre-start checks to the decision to reschedule.
A blast nozzle can look serviceable while its bore has already opened enough to disturb pressure, media flow and finish. This guide sets out a practical weekly measurement and retirement routine for UK contractors who want nozzle wear managed as a cost-control issue, not an afterthought.
A used blast pot can be the best value purchase a small blasting firm makes, or the most expensive one. This guide sets out the paperwork, shell measurements, control-system tests and valve inspections that should happen before money changes hands — and explains why the ticket price is only the beginning of the arithmetic.
The fine fraction produced inside a blast room is rarely inert, and in a confined enclosure it behaves very differently from the same dust outdoors. This article examines how spent media and coating debris accumulate, what DSEAR expects of a blast room operator, and which housekeeping, ignition-control and fire-watch arrangements hold up under scrutiny.
An undersized air system rarely fails outright; it simply delivers less pressure, slower work and a less consistent finish. This explainer sets out how to calculate nozzle demand, account for hose losses and choose a compressor, hose and nozzle combination that holds pressure through the shift.
On city-centre and occupied-building projects, the blast enclosure is only one part of the boundary that needs managing. This field guide sets out a practical approach to containment screens, dust and noise control, neighbour liaison and emergency access, with a one-page checklist for the site boundary.
Cleaning historic fabric is a conservation decision before it is a blasting decision. This guide covers trial panels, media and pressure selection, containment in sensitive locations, and the documentation that convinces a conservation officer and a client at the same time.
Hourly rig rates remain the default in UK surface preparation, yet they reward attendance rather than achievement and leave both parties exposed when a job runs long. This piece sets out the commercial case for quoting against measurable outcomes and explains how to build a contract that holds up under scrutiny.
Classification problems on blasting projects rarely begin at the skip; they begin at the survey. This operational guide sets out how to assess, segregate, label and record spent abrasive so that the waste leaving site is described accurately the first time and the paperwork holds together at audit.
A blast-clean surface is chemically eager to oxidise, and a British autumn will happily oblige. This guide sets out how contractors can measure, control and document the interval between blasting and priming so that a substrate never leaves the yard in a condition the client did not pay for.
A live-site blasting job can fail long before the first pass if moisture, salts, incompatible coatings or poor containment go unchecked. This 12-stage audit gives facilities managers and contractors a formal handover routine, plus a case example of costly rework.
