Blasting Questions and Answers
Why get your boat blasted?
Over a number of years antifoul builds up so that the underwater hull surface is no longer smooth which is not efficient and it also is not good for antifoul adhesion. Ideally this build-up of antifoul should be removed back to the hull every five years or so. Not only is this a very time consuming job but it is also potentially messy and unless care is taken will introduce toxic paint into the environment.
How does our blast system differ from regular blasting?
We use a combination of recycled glass crushed to a fine grit and water which has the benefit of the abrasion of sand but with no dust produced. Our blasting system will completely remove all of the old coatings, leaving the original gel coat with a fine etched finish that is clean and prepared, ready for new coatings. The process also exposes any weaknesses in the gel coat such as blistering or voids allowing them to be filled prior to re-application of the surface coatings. By blasting in a purpose built site all waste material is contained and disposed of as hazardous waste by a professional waste management company.
Will it damage the underlying gel coat?
Our system is highly controllable meaning almost any desired finish can be achieved. It is always dependant on the underlying substrate and so if there are weaknesses or voids in the gel coat then this will be exposed. The blasting system will give an etched finish due to the impact of the blast medium (ie fine glass grit and sand). Please note that Jeremy Rogers Ltd is not liable for the state of the substrate uncovered by sandblasting. Should remedial work be required to get the hull to a condition suitable for coating then this is not included in the cost of the blasting.
Can the blast system be used for removing gel coat?
Whilst it is possible to remove gel coat with it is recommended to have gel coat removed by an experienced professional with a gel peeling equipment to ensure the depth removed is consistent. If this is part of an osmosis job then the fibre glass substrate layer is usually opened up and any voids revealed using the blaster.
How long does it take?
The boat is usually in the shot blasting bay over a three day slot, although the blasting itself is usually done in one day.
Can you remove back to an epoxy layer without going back to the gel coat?
It is usually possible to take the antifoul back to a layer of epoxy coating and is recommended. To remove an epoxy layer in addition to the antifoul can be much more time consuming and there is an additional cost. Please contact us for more details.
What coatings should be reinstated after the anti-foul has been removed?
This depends on the condition of the hull and what type of anti-foul or foul release system is desired. Typically any voids would be filled (the cost of this will be dependent on the condition of the hull and what remedial work is required)
Following this there are various options. Sometimes a boat requires peeling and relaminating before epoxy coating if osmosis is present. After this the antifoul coatings can be applied, these range from the standard copper based antifoul, to coppercoat and the foul release style silicon based coatings.
Will my keel get blasted too?
Yes, we would normally sandblast this as part of the job. NB. If your keel is iron and not encapsulated then it is important that the exposed metal is sealed rapidly with a good quality epoxy coating to ensure it does not rust. (There is an additional cost for this)
What do I need to do to prepare my boat for blasting?
It is important that the boat owner takes responsibility for ensuring that the boat is ready to be blasted; all through hulls must be closed and stern gear and props should be protected. If this is not carried out then Jeremy Rogers Limited will carry out the work and there will be a charge to the customer.
How much will it cost?
We assess each job on an individual basis based on existing coatings that are required to be removed and what is required to repair any voids following blasting, as well as the size of the hull. As stated above, Jeremy Rogers Limited is not liable for the state of the hull that is exposed by the blasting; any remedial work required to get the hull in the correct condition for coating will be discussed with the owner post blasting.
