Newly plaster skimmed walls take approximately 4 days to dry out before you should attempt to decorate them. It is crucial to wait until the plaster has dried, and its colour has changed to a pale pink. There should be no brown patches as a guide. In some instances, you may need to wait up to 4 weeks.
The best condition for allowing your newly plastered walls/ceiling to dry is to provide some ventilation by opening a couple of windows slightly. You can put the heating on, however, we recommend you keep this at a low temperature for a number of days after the plastering is completed.
After applying a skim coat, it's generally recommended to wait at least 24 hours before painting. However, the exact drying time can depend on several factors, including:
MAKE SURE YOUR WALLS ARE COMPLETELY DRY. This can take a maximum of 7-10 days, depending on the conditions in your home.
Depending on the severity of the damp and the type of wall, it could take anywhere from a couple of weeks to a few months for the wall to fully dry out.
Use fans to move air around the damp walls. Also use dehumidifiers, which can help remove moisture from the air and walls. Professionals use tools like moisture meters, infrared imaging devices, dehumidifiers and heavy-duty fans. That ensures the walls are truly dry before further repair, painting or refinishing.
mildew and mold will develop within 24-48 hours of water exposure. Even worse, it will continue to grow until steps are taken to eliminate the source of moisture, and effectively deal with the mold problem. Use the diagram on the facing page to assess the extent of mold in your home.
If you leave wallpaper or lining paper on the wall, it can absorb moisture from the plaster and cause issues with the setting of the plaster. Also, if you plaster over the wallpaper or lining paper and the paper comes unstuck, it will cause your plaster to fail and you're back to square one.
If there are any chips, holes or noticeable scratches in the wallpaper, it's better to strip the wall instead of painting over the wallpaper. The paint won't completely cover up these imperfections, so it's easier to strip the wallpaper and paint the wall direct if you want a flawless finish.
Skimming. If the texture on the walls has been painted it won't be possible to use the soak and scrape method as the paint will repel the water and keep the texture from softening. That means you will need to apply a skim coat over the entire textured surface that will receive the wallpaper.
Generally, it takes a few hours to overnight for a skim coat layer to dry. Always follow the manufacturer's recommendations and allow each layer to dry completely before sanding and applying the next coat.
If the paint is in good condition and not in need of any maintenance, it is perfectly fine to skim over it with plaster. However, if the paint is old, flaking, or damaged, it is recommended to remove it before plastering.
Don't paint directly over new plaster walls because the glossy surface can prevent the paint from adhering effectively.

While painting over mould may temporarily disguise the problem, paint alone will not kill mould. Instead, the mould will continue to grow underneath the paint until it begins to show through. It may also cause the paint to bubble or flake, ruining the finish. If possible, it's best to remove the mould before painting.
If you are in a cold, damp, or humid environment you may even want to wait up to 3-4 weeks. Installing Removable Wallpaper on a fresh, uncured painted surfaces may result in poor adhesion or the decal may damage the paint upon removal or cause a color shift in the pattern area.
Repair Any Cracks and Holes
If the wall surfaces are really poor, consider getting them skimmed with a layer of plaster, or use a thick grade of lining paper to provide a smooth surface for the wallpaper.
If you're wondering whether or not to overlap wallpaper, the answer is a resounding yes! When you receive your removable wallpaper or mural, you'll notice an "OVERLAP" sign at the top of each panel. This sign indicates that the edges should be overlapped by one full inch when installing the next panel.

This task can be daunting, yet if done correctly, texture painting over wallpaper is possible and even enjoyable! Below are tips on identifying the appropriate wallpaper and paint to ensure successful results.

Your sense of smell is the first line of defense against mold. You can often smell mold before you can see it. If you notice a musty smell in your home, there's a good chance you have mold. If you think you have a mold problem, get on your hands and knees and smell the electrical outlets.
To dry out small spots, place a fan in front of the damp area and turn it on high. For larger spots, install a heavy-duty dehumidifier in the room to suck the water vapor out. If you need to dry out a wall in an enclosed area, place moisture absorbent materials like dehumidifier packs near the damp spots.
