Our window sills can get ignored and fall into disrepair all too easily, but they deserve just as much attention as the rest of the home. So when you’re next giving the place a spruce up, think about taking the extra time to properly paint your window sills!
If you’re looking for expert tips on how to paint a window sill, follow our easy steps and create the perfect window area to daydream from.
When it comes to painting a window sill like a professional, the first step is to prepare the area for painting. First, remove any furniture or décor from the room to avoid obstruction and damage to your belongings. Next, take down any curtains or blinds from the area you’re looking to paint and lay down a Seriously Good Dust to protect the area and prevent paint from seeping through and causing any stains to your flooring. To secure your dust sheet in place whilst protecting the area around the window sill and window frame, use some Seriously Good UV Masking Tape. The next step is surface preparation!
Wood preparation can be a challenge as areas of trim such as window sills can often go neglected for extended periods.
To achieve a smooth, matte surface that is ready for painting, begin sanding the wood using the Ultimate Aluminium Oxide Fine Paper in gentle, circular motions to remove old paint and imperfections. Repeat this step using the Seriously Good Fine Sanding Block to ensure that all old paint has been removed. For thicker, more stubborn paint, you may need to wear protective equipment, like our Seriously Good Nitrile Gloves or Seriously Good Safety Glasses before applying paint stripper to the wall. Pour some of the paint stripper into a small metal or glass container and apply to the desired area. Be sure to closely follow the product guidance and safety procedures to achieve the best possible results.
Once all paint has been removed, the next step after sanding is cleaning the dust away using a Seriously Good Microfibre Cleaning Cloth. You then need to assess the surface of the wood again and repair any holes or cracks in the woodwork using wood
filler. Once the filler has cured, sand and clean the surface once more using Ultimate Aluminium Oxide Paper Fine and sugar soap to make sure your paint applies perfectly.
The key to painting a window sill smoothly is applying a high performing primer. Two main areas need to be primed in this step; the first is any detail areas and second is the window frame and edges of the window sill. We recommend opting for a stain block primer to mitigate any sap or contaminants from spoiling the wood and the paintwork. To help ensure even coverage when applying the primer, use the Ultimate Angled Gloss Brush.
For larger flat areas such as the shelf of the window sill, use the Ultimate Woodwork Gloss Roller 4” Set to speed up the process and paint effortlessly. When you have finished applying the priming coat, clean the brushes using some white spirit in a sealable jar, such as a mason jar or jam jar to prevent sink blockages. Work the white spirit into the brush and then wipe away the paint with some Seriously Good Paper Towel.
Repeat this easy cleaning process as necessary until the brush is fully clean and ready to be reused in the exciting final step! Remember, you cannot re-use the gloss roller sleeve, but you can wrap it in cling film for use priming another part of the house. This should keep the roller sleeve moist and usable for around 48 hours.
Before applying the final top coat when painting a window sill, it is advisable to give the primed surface a quick, light sand using some Ultimate Aluminium Oxide Fine Paper. This quick step helps to remove any annoying brush marks from the priming stage and gives a much smoother, more professional-looking finish. Clean the area one final time with a Seriously Good Microfibre Cleaning Cloth to effectively remove dust from the area.
Repeat these painting steps using the Ultimate Angled Gloss Brush for detail areas and the Ultimate Woodwork Gloss Roller 4” Set for the flat surfaces for your top coat. Don’t forget, you can clean your expert painting tools and ensure they offer maximum performance again and again by using white spirit to quickly remove the gloss paint.
