Hi @Taz2,
Thank you for your question about painting the exposed wooden beams in your toolshed.
The majority of the work for painting projects comes before painting and giving the beams a good pressure clean is a great first step.
Now that they are clean, I'd suggest giving them a good sand with a random orbital sander with some 120-grit sandpaper. Once sanded, brush them down with a soft bristled brush to remove any sawdust.
In terms of painting tools, there are two main options, paint sprayers and a combination of paint rollers and brushes. If you were to use a paint sprayer, you would need to mask off any areas you do not wish to paint using masking tape and drop sheets to prevent overspray from getting onto unwanted surfaces. If you were to use rollers and brushes, you would still need to mask off some sections to get nice clean lines and protect the floor, but you wouldn't need to quite be as diligent.
In terms of paint to use, as it looks well enclosed, but not truly indoors, I'd suggest using Dulux Weathershield Exterior Paint, just make sure to wear a mask and leave as many doors open as possible so the fumes can dissipate.
To calculate how much paint you need, you'll need to work out the surface area you are looking to paint. Dulux Weathershield will cover approximately 16sqm with 1 coat of paint. It is recommended to use 3 coats on bare surfaces so each litre of paint will cover approximately 5.33 sqm of area with 3 coats of paint.
