Liquid coating roof system in Tenby

JOP Ltd. Have been carrying out works on a property in Tenby, which involves specialist roofing materials to provide high quality and long lasting protection for the roof.
JOP are approved contractors and applicators of specialist Decothane products.
The initial roofing works involved installing a raised GRP trim, followed by the priming of the roof itself before installing a Vaper Carrier layer.
The detail work was carried out by using Decothane Ultra base coat and re-mat embedded into it, which covered not only the flat surface, but the incline as well.

Finally the works were completed with a Decothane Ultra top coat to seal and provide further protection for the roof.

Swansea Coastal Path – Langland to Caswell Bay.

JOP Ltd were awarded the contract for the resurfacing of the coastal path between Langland Bay and Caswell Bay, The Gower by the City & County Council of Swansea.

The works are located on the existing coastal path with rising coastal slopes, rock outcrops and cuttings through friable soils on the lanward side and both coastal slope and cliff edges to the seaward side of the pathway.

The works include the bench cutting of the inland side of the footpath to allow the laying of a new 1500mm wide gritstone aggregate footpath. The completed footpath will remove risks of the path being undercut/eroded, eliminate dangerous cross cambers, awkward slopes and steps, and be more suitable for pushchairs and wheelchairs.

Fireproofing at Puffin Produce

JOP Ltd were awarded the contract to carry out intumescent fireproofing on the new steel structure expansion for Puffin Produce in Haverfordwest.

The work involved prepping the steel work, priming it and apply the fireproofing with rollers and brushes before top coating (as requested by the client in an anthracite grey). All of the outside steel work has now been fireproofed and top coated.

Laugharne club house fireproofing for WB Griffiths

JOP Ltd were awarded the contract to carry out fire proofing on the new steel structure for a new clubhouse at Seasons cottages holiday park in Laugharne. The principal contractor carrying out the building works were WB Griffiths and JOP worked under them whilst carrying out the fire proofing.


• July 2018 – We inspected the steel structure and drawings and submitted our quote.
• August 2018 – We were awarded the works and commenced the second week in August. The work involved prepping the steel work, priming it and spraying the fireproofing before top coating. Due to two areas of the clubhouse being high in moisture (swimming pool and sauna areas), a specific type of top coat was needed to provide an extra layer of protection to the fire proofing.
• September 2018 – Works completed, one week ahead of schedule.

JOP staff are highly trained in fireproofing and coatings application (including rolling and spray application) and our painting inspector and supervisors have had 20 years plus experience of industrial coating application.

JOP always treat health and safety as our top priority and this contract was completed with over 1,000 hours on site with zero incidents or injuries.

JOP management undertook regular site visits to ensure the high standard of health and safety is being maintained on site.

A full QA pack was submitted to the client in line with our International applicators licence to give standard warranty cover for the client.
