Osmosis showing on Hull of a Yacht



Osmosis is generally associated where fibreglass and polyester resins have been uses.

This system is used in the production of modern yachts where Osmosis is most likely to occur.

The cause is where moisture ingress into small voids which occur during the fibreglass and polyester system.

Initially small blisters become visible and over a period of time increase in size.

For example this problem can also occur where concrete swimming pools have been

constructed and the inner areas coated and where the outer membrane has failed.

The water pressure present in the surround ground level caused moister ingress into the substrate and blisters of the paint coatings.


To concrete structures where Osmosis has occurred the faulty membrane should be replaced and the defective coating removed back to a clean surface. Followed by repainting one the moisture content of the substrate is below 12%.

Spraying Airless Common Problems and Remedies

Airless Spraying and Equipment
Common Problem and Remedies

Airless spray equipment is based on an electric motor (petrol driven motors are available) and hydraulic pump driven system to delivers paint/coating products under very high pressure up to 3000 pounds per square inch (PSI) to the spray gun.

Motor unit does not run or stops.
a) Check the origin of the power supply and all connecting cables followed by pressing the reset button.
b) Check the fluid control settings.
c) Confirm the switch in the ON position and the pressure control regulator is correctly set to maximum pressure setting.

Cannot Prime
a) Pump inlet suction filter blocked. Remove and clean.
b) Air in the hose or pump. Seal or replace.
c) Valve set on prime. Turn key onto spray.
d) Air in pump or hose or inlet filter blocked.
e) Check the piston packing has not dried out and the ball valve is free.

Material too viscous.
a) Confirm manufactures’ data for product viscosity and thinning ratios.
b) Check syphon tube for blockages or air leaks.

Pressure not being maintained
a) Filter to pump inlet – clean.
b) Pressure setting too low - increase
c) Air in either pump or hose – with spray gun trigger held open for 10-15 seconds to clear any air.
d) Spray tip too large.

Irregular and poor spray pattern
a) Size of spray gun tip incorrect- change tip.
b) Incorrect pressure – Adjust as necessary.
c) Material too viscous – adjust with correct thinner to manufactures recommendations.

Cannot shut off material supply at gun.
a) Thoroughly clean spray gun with product thinner/solvent.
b) Needle stop nut too tight- loosen slightly.
c) Needle worn – replace.

Spray gun will not operate.
a) Safety trigger on.
b) Inline filter blocked – Clean or replace - Adjustable tip blocked.

Spray pattern has Tails and strips:
a) Pressure too low – increase pressure.
b) Paint too viscous – see manufactures data for thinning.
c) Tip too wide – Adjust to reduce pattern size.
d) Spray tip worn – Replace.

Pressure does not increase when paint is drawn up:
a) Bypass valve in prime position -Turn valve to spray.
b) Air in hydraulic system – Bleed system.
c) Pressure valve incorrectly adjusted or worn sprat tip.

Spray pattern uneven:
a) Blocked or worn spray tip – replace tip.

Spray tip keeps clogging:
a) Contaminated material – Check inline gun filter.
b) Dry paint in spray tip - clean.

Pump not drawing up material.
a) Suction tube either loose or damaged drawing in air.
b) Suction tube not immersed in the material.
c) Suction Filter blocked.

Pump primes but no pressure.
a) Suction filter blocked – remove clean or replace.
b) Prime switch not set to spray.

Waste Disposal (Paint and Hazardous Liquids)

Waste Disposal.


On construction site the disposal of building waste including paint and hazardous materials and liquids should be cover at your site induction toolbox talk.

At this time information advising  the location areas  of the  disposal facilities should be included.

Checks should be made with the local authorities regarding the local facilities and regulations for commercial and domestic wastage.

Under no circumstances should paint products be disposed of into the nation water drainage system.

Part used paint containers should be filled with either sand or sawdust to consolidate the liquid and allow to dry be for disposal.

Dirty solvent (white spirit etc.) is classified as hazardous and should labelled according as this type of product can be reclaimed. 


Part tins of water based paints are available they could be offered to a local community organisation.

Dirty solvents.  After washing out brushes/rollers sleeves the solvent can be reclaimed for future use by transferring into a larger container. Once the solids have settled to the bottom the solvent can be syphoned off and reused.

A number of decorators merchants such as Johnstone Paints, Dulux and Crown Decorating Centre offer facilities where they will

take back used paint containers. Check local branch for terms and conditions.
