What to do once your shed has been delivered

1 - Waterproofing your new shed

All of the timber buildings made here at the Superior Sheds Swansea come pressure treated as standard. Pressure treatment forces preservatives deep in to the timber to prevent attack from fungus, insects and bacteria that cause wood rot. Pressure treatment does not waterproof the timber.

Timber is an absorbent material and needs a water repellent preservative oil 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 it has been delivered.  

The 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.

We stock the high quality – Welsh made premier Q wood preservative at our unit. It is a solvent based wood preservative that is also wax enriched. This high quality product causes rainwater that lands on the shed walls to bead off before it gets a chance to soak in to the structure.

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.

Leaving the shed door open on dryer days will allow air to pass in and out of your shed and will allow any moisture that has managed to enter 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.

If you opted for our felt covering then you should inspect the felt every 6 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.

Any rips or tears that are not immediately attended to can let water in through the roof and cause damage to the roofing boards.
