What to do once your shed has been delivered
1 - Weatherproofing and preserving your new shed
All of the timber buildings made here at the Superior Sheds Swansea come pressure treated (TANALISED) as standard. Pressure treatment is the best timber preservative method known to man. A special vacuum tank is used to force preservatives deep in to the timber to prevent attack from fungus, insects and bacteria that could cause premature wood rot. Pressure treatment does not waterproof the timber. Timber is an absorbent material and needs a water repellent preservative oil applied to it to minimise the amount of moisture that is able to pass through it.
It is extremely important that a high quality waterproofing oil / preservative is applied to your garden building as soon as possible once it has been delivered. We advise two heavy coatings for the entire exterior of the shed. Any exposed sides should get an extra coating to help with waterproofing. The sheds interior should also get a coat of preservative. Be sure to coat all walls, the roof boards and the floor. (Do not coat the walls if you have a breathable membrane installed. You can coat the framing timbers though) You have just purchased a great shed so be sure to follow the steps above to ensure it lasts as long as its meant to.
Waterproofing preservative should then be applied annually or when rain starts to soak in to the structure instead of beading off like it does on a freshly polished car. The best time to give your shed its annual coat of preservative is towards the end of summer. This will help to give maximum protection during the harsh winter months.
If your shed has been fitted in to a tight space, you can buy a pump sprayer to reach all parts of the shed.
We do not advise using water based preservatives for waterproofing. Solvent / oil based preservatives are far more effective and penetrate much deeper in to the grain.
2 - Controlling damp and mould
A garden shed is a single skinned timber structure that is sat outside in all weathers. Due to the driving winds and rains that we experience in Wales, it is inevitable that moisture will get in to the shed in some way shape or form whether it be from the wind blowing rain through joints or from condensation forming when the air in your shed is warmer that the air outside.
Ventilation is key to controlling moisture levels within your shed. Due to there being no heating, cavity wall or insulation installed as we have in our homes, when weather conditions are correct, condensation will form within the shed.
Leaving the shed door open on dryer days will allow air to pass in and out of your shed and will allow any moisture to safely evaporate away before it can cause any mould or damp issues.
3 - Maintaining the roof
If you opted for our maintenance free rubber roofing system then you do not need to carry out any roof maintenance. A simple check of the roof covering every now and then for any signs of damage from pests is all that is needed.
If you opted for our felt covering then you should inspect the felt every 3 months or after strong winds to ensure there are no rips or tears. Although the felt we use is of very high quality and has polyester reinforcement to prevent tearing, very strong winds blowing in the correct direction can still cause damage to your roof covering.
You should also check your felt covering for any signs of damage from pests. Cats, mice, rats, squirrels and birds are just a few of the animals that can find their way on to your roof and puncture / chew holes in your roof covering.
4 - Rainwater Management
If you opted for our guttering option then you do not need to worry about this section.
Guttering catches any rainwater that falls from the roof, stopping it from hitting the ground and bouncing up on to the bottom cladding boards and plywood base of the shed.
Laying chippings in the area where the water is landing to diffuse the water can help combat this issue but fitting guttering is the best thing to do. We strongly recommend that you fit guttering to your shed as soon as it has been erected.
5 - Windows
Windows should be inspected annually. Due to the way that timber expands and contracts during the seasons it may be necessary to re apply silicon to the windows and to the underside of the bottom bead on an annual basis to make them as watertight as possible.
