Choosing Unsuitable Materials
While vinyl, washable and moisture-resistant papers are ideal for bathrooms and kitchens, using regular paper wallpaper in these wet areas is a big mistake. Paper wallpaper absorbs moisture and encourages mould in humid rooms. Similarly, lightweight wallpapers can peel in high-traffic spaces. Always pick materials suited for the room.
Improper Surface Prep
Skimping on surface prep can make wallpaper lift off or peel. Start by cleaning walls thoroughly and removing any existing mould or flaking paint. Fill holes, fix cracks and sand bumps for a smooth finish. Primer helps seal porous surfaces while sizing creates a protective layer for better adhesion.
Miscalculating Required Amount
Nothing's worse than being short of wallpaper mid-project. Measure room dimensions accurately and calculate the precise area to cover. Add 5-10% extra for pattern matching and wastage around corners or electrical points. Having a few spare rolls avoids patchy results.
Applying Wallpaper on Damp Walls
Never apply wallpaper on walls that are damp or have moisture trapped behind old paint or plaster. Use moisture meters to check for dampness. Allow fresh plaster to dry completely over several weeks before wallpapering. Dampness beneath causes wallpaper to lift or bubble up.
Failing to Acclimatize Paper
Wallpaper straight from the shop can shrink after application as the paste dries. This leads to sagging seams and edges lifting up. Always unroll wallpaper and let it sit in the room for 1-2 days before pasting so it acclimatizes and adjusts to the room's temperature and humidity.
Using Too Much or Too Light Paste
The right consistency paste sticks wallpaper securely without overflowing at edges or leaking through. Too light paste won't adhere properly while too much paste makes papers stretch out of shape as it dries. Follow paste directions carefully for optimal stick.
Rushing Through Installation
Taking shortcuts during wallpaper installation affects the end results. Don't rush through steps like pasting the edges, smoothing out air bubbles and trimming excess paper along ceilings or skirtings. Neatly installed wallpaper has straight seams and crisp edges.
By learning from these common mistakes, you can avoid wallpaper disasters in Singapore's humidity. Pay attention to materials, prep work, measurements and technique for stunning wallpaper application that enhances your interiors long-term.
