Applying yacht and boat paints/coating materials using spray methods
Overview
This standard identifies the competences you need to apply yacht or boat paints/surface coatings to various substrates, using spray guns, in accordance with approved procedures. You will be required to obtain all information necessary to carry out the spray painting/surface coating activities. You will be required to check that all surfaces to be painted/coated have been correctly prepared and that any necessary exclusion, containment, masking, protection and ventilation requirements are implemented. You will be expected to use the appropriate and/or specified equipment and to ensure that it is correctly set up, maintained and adjusted. You will be expected to apply a variety of paint/surface coatings in a number of boatyard environments.
Your responsibilities will require you to comply with organisational policy and procedures for the yacht or boat spray painting/surface coating activities undertaken and to report any problems with the spray painting/coating activities, materials or equipment used, that you cannot personally resolve, or are outside your permitted authority, to the relevant people. You will be expected to work with either a high level of supervision or as a member of a team. You will take personal responsibility for your own actions and for the quality and accuracy of the work that you carry out. Where team working is involved you must demonstrate a significant personal contribution during the team activities in order to satisfy the requirements of the standard and competency in all the areas required by the standard must be demonstrated.
Your underpinning knowledge will be sufficient to provide a sound basis for your work and will provide an informed approach to applying liquid paints/surface coatings to yachts or boats using spray methods. You will understand the spraying procedures and techniques used and their application. You will know about the substrates, their preparation requirements, coating materials and their preparation requirements, in sufficient depth to provide a sound basis for carrying out the activities to the required specification.
You will understand the safety precautions required when carrying out the yacht or boat spray painting/surface coating operations. You will be required to demonstrate safe working practices throughout and will understand the responsibility you owe to yourself and to others in the workplace, both ashore and afloat.

Knowledge and Understanding
You need to know and understand:
- the safe working practices and procedures to be observed when carrying out manual spray painting/surface coating activities on yacht or boat components (such as general workshop and site safety, appropriate protective equipment, protecting other workers from the effects of the work, safety in enclosed/confined spaces, working at height, use of mobile elevated work platforms (MEWPs), use of atmospheric controls)

- the requirements for working in confined spaces and the importance of emergency procedures and safe systems of work (including safe evacuation, closing down compartments, permits to work, Required Air Quantities (RAQs) and local exhaust ventilation (LEV), to maintain safe conditions; the provision of adequate and safe lighting and avoidance of sources of ignition
- the personal protective equipment (PPE) to be worn during the spraying activity
- the characteristics of and the applications for yacht or boat paint/surface coating products (including the use of manufacturers' data sheets, requirements for the application of particular coating systems)
- the need to ensure that the substrates have been prepared correctly for the coatings to be applied
- the importance of maintaining appropriate environmental conditions for the application and curing of the surface coating products
- the time intervals that are required between coats and why these must be adhered to
- the procedures for the handling and safe use of coating materials and solvents
- the use of paint thinners to adjust the viscosity of the product being applied.
- selection of the application equipment to suit the materials and the finish required (to include spray gun atomising and air control, tip size, fluid delivery rates and fan angle)
- the principles of correct air flow and its effect on quality and safety
- the correct grounding and earth continuity of the equipment
- the requirements for cleaning spray guns (including the cleaning of the diffuser, tip and tip guard, the flushing of the gun and of the lines, the lubrication of the needle)
- the techniques required for the application of paint/surface coating products to a variety of surfaces
- the requirements for working afloat, on outer bottoms and at heights
- the importance of avoiding overspray; the need for containment and for exclusion zones
- the procedure to contain and to clear away spillages.
- the identification of faults in application and their causes and correction (to include distorted patterns, tailing, dry spray, over spray and pinholing)
- simple non-destructive testing procedures to ensure that colour, gloss, adhesion and other required performance qualities are achieved
- why tool/equipment control is critical and what to do if a tool or piece of equipment is unaccounted for on completion of the activities
- minimising and handling waste materials (including the environmental impact of the materials you are using and the minimisation of this impact)
- the extent of your own responsibility and whom you should report to if you have problems that you cannot resolve
