What to Expect on a UPVC Spraying Job: From Survey to Finish

What to Expect on a UPVC Spraying Job: From Survey to Finish

If you have never had UPVC sprayed before, it helps to know exactly what happens — because a good result is mostly about the parts you do not see. Here is the whole process, from first survey to the finished frames, and the little you need to do to prepare.

This is how every job runs through our UPVC spraying service across Hampshire.

1. The Survey and Quote

It starts with a look at the actual frames. The survey confirms the material, the condition of the surface, how much preparation is needed, the colour and finish you want, and access. That is what a fixed written quote is built on — not a phone estimate — so the price you are given is the price you pay.

2. Preparation — Where the Result Is Won

On the day, the overwhelming majority of the time goes into preparation rather than colour. Every frame is thoroughly cleaned and degreased, lightly abraded so the new coating keys to the plastic, and any repairs made good. A sprayed finish that fails almost always failed here — on unprepared or greasy plastic — which is why this stage is not rushed.

3. Masking

Glass, walls, sills, ironmongery and everything around the frames is carefully masked. Good masking is the difference between crisp, factory-clean edges and overspray, so this is meticulous. Inside the house, nothing needs to move for external frames.

4. Spraying

An adhesion primer made for UPVC goes on first, then specialist topcoats are spray-applied in thin, even coats for a smooth, consistent film with no brush marks or runs. Any RAL or BS colour is available — see our guide to UPVC window spraying costs, colours and process for the colour side.

5. Drying and Curing

The coatings are touch-dry quickly and windows can normally be used the same day, with the finish continuing to cure and harden over the following days. Most homes are completed in one to two days depending on the number of frames — our guide to how long UPVC spraying takes breaks the timing down.

How to Prepare Your Home

• Clear access to the windows outside — move bins, pots and garden furniture away from the elevations.
• Trim back plants and shrubs touching the frames if you can.
• Keep windows closed on spraying days, and let the team know about pets and parking.
• That is genuinely all — the preparation of the frames themselves is the sprayers’ job, not yours.

After the Job

The finish needs nothing more than the occasional gentle wash — our sprayed UPVC aftercare guide covers keeping it looking new — and the work is backed by a written guarantee confirmed with your quote.

Frequently Asked Questions

How should I prepare for UPVC spraying?

Very little is needed: clear access to the windows outside, move bins and furniture away from the walls, trim back plants touching the frames, and keep windows closed on the day. Preparing the frames themselves is the sprayers’ job.

Do I need to be home while the windows are sprayed?

Not necessarily, as long as the team has access to all the external frames and any parking or gate arrangements are agreed in advance. It is worth being contactable in case of questions.

Can I use my windows the same day?

Usually yes — the coatings are touch-dry quickly and the frames can normally be used the same day, with the finish continuing to cure over the following days.

How long does a typical house take?

Most homes are completed in one to two days depending on the number of frames and the amount of preparation required. The survey confirms the timing for your property.
