Painting a facade
Find out how
Each substrate poses a different challenge for paint, and each builder has their own ideas as well. Take your time and inform yourself. What is particularly important to you? Then make a conscious decision about your paint product.
Testing – the basis for a secure connection
In particular on exterior areas, it is important to examine the substrate carefully. Can the substrate carry the load? Where is dirt and initial damage recognisable? A simple wiping test by hand can provide some information in this case. Is the render or paint flaking off, or can you scratch off the paint with your fingernails? If so, a "cross-cut test" absolutely needs to be carried out. A chessboard pattern is cut into a small area of the old coating with a carpet knife and masking tape is then firmly pressed onto it. The masking tape then needs to be pulled off quickly. If parts of the old coating remain stuck to the masking tape, then this means that it can no longer bear the load and needs to be removed.
It's all about having the right tools
Ensure you have good-quality tools! Proper tools make work easier and improve results. Buy your tools from a professional retailer. Pay attention when buying paint brushes – they should have a dense tip with stiff bristles, so that you have more control when painting. When working outside with rollers, it is recommendable to use a roller with long bristles made of polyamide.
Safety is the most important thing! Meaning: When working on a facade, scaffolding should be erected. This makes work easier, faster and – more than anything – safer!
Divide your facade into sections before you start painting.
Do not interrupt the painting work in the middle of a section. This avoids an unattractive "stop-start" appearance!
Protect adjacent areas, such as windows, and mask carefully.
Only use masking tape that is suitable for outdoor use when doing this – there are significant differences depending on the respective application. Remove the masking tape promptly; it can otherwise not be removed without leaving residues.
Never paint when it's raining, in strong winds or on a damp substrate. Heat is also not optimal. It is best to start with the south side of a building. This means that you work with the journey of the sun around the building, allowing you to paint in the shade. Substrates that are too hot make the paint dry too quickly – that is bad for the final result!
Always remove paint splashes immediately. Use plenty of water to do this. Remove the downpipes, awnings and similar in advance where possible. That does entail extra work – but it will make things faster in the long run.
