The refurbishment design introduced a suspended ceiling while retaining the existing structural steel without boxing it in.
The accepted project information identified a 60-minute fire-resistance requirement for the relevant beams and columns.
The existing coating had failed in areas and corrosion was present on the steel. A thorough preparation process was therefore needed before the new primer and intumescent coating could be applied.
The work area was unoccupied, allowing the package to be completed during normal day shifts.
Our scope covered cleaning and abrasive blast-cleaning of the existing beams and columns to Sa 2½, application of Manor QD Phosphate HB420 primer and airless-spray application of the specified Thermoguard intumescent coating.
The failed coating and corrosion were removed by abrasive blast-cleaning to Sa 2½.
The prepared steel was then primed with Manor QD Phosphate HB420 before the specified Thermoguard intumescent coating was applied by airless spray.
The work was completed during day shifts within an unoccupied work area, giving the team clear access for preparation and coating across the ten-day programme.
The preparation and coating package was completed over ten working days as part of the community-centre refurbishment.
The existing beams and columns were taken from a failed, corroded condition through to a newly prepared, primed and intumescent-coated finish.
The photographs show the condition of the existing steel, the abrasive preparation process and the newly coated beams and columns.
Send us photographs, drawings and the available project specification. We can assess the steel condition and advise on an appropriate on-site survey, preparation method and coating programme.
