How important is it to prepare the surfaces before applying any vinyl?
It is fundamentally vital that all surface areas are prepared before applying any vinyl product. This cannot be stressed enough. If not prepared properly vinyl graphics can look cheap and peel off, or even damage paint and drywall. Surfaces have to be smooth and clean for vinyl to be able to adhere to them. You can apply vinyl to glass, steel, walls, plastic and even wood. The wood has to be smoothly sanded and painted or primed for the application to be successful.

How to prepare the surfaces
The Soapy Solution
Clean the area of dirt and grease before continuing with the application of the vinyl. Make the solution by using an ordinary garden trigger spray bottle and mixing 2 tablespoons of mild dishwashing detergent with a quarter of warm water. Spray the fluid over the relevant area of the surface, and wipe and dry with a clean cloth. Keep the application fluid because in some cases you will be using it again during the application of the vinyl product.
Using the soapy solution during the application
The soapy water reacts with the glue of the vinyl when applying vinyl helping you smooth out wrinkles and bubbles easily. Just be mindful of not adding too much water. The vinyl is easy to reposition during this phase while the surface is still wet underneath. If there is too much water under the vinyl it will take much longer to get out and could create water bubbles if not removed properly. The vinyl is only “stuck down” once all the water has been removed. Read more about the vinyl application here.
PVA Painted Walls and the Curing Period
Vinyl decals apply without hassle onto PVA-painted surfaces after the curing period has lapsed. Before applying decals, ensure that the paint on the wall is acrylic-based and has been applied with a flat, smooth finish. Vinyl will NOT stick on walls that have been painted with PVC-based paint (e.g. with Teflon) unless it has been treated with a primer. Cure the paint for approximately three weeks before applying the vinyl decals.
Vinyl and Wall texture
Be aware of what walls you will be applying vinyl to. Vinyl can’t be applied to walls with rough textures the glue won’t adhere to it. There is a speciality vinyl option available for brick and prefab but it is costly & time-consuming, looks fantastic though.
Room temperature is a factor
The temperature in the room place a factor in the application of vinyl. The best way to avoid peeling is to apply the wall decals initially when the room’s air temperature and the surface of the wall range between 20 – 30°C. Lower and higher temperatures will not produce the desired end result.
