Considerations Before Wallpapering Over Existing Wallpaper

Discerning clients expect a flawless result. We study structural stability and existing design elements to confirm the viability of layering.

Assessing the Condition of Your Current Wallpaper

Stripping is often ideal when the surface shows severe tears or peeling. Minor flaws remain manageable if the underlying layer stays secure. 

Understanding the Material of Your Current Wallpaper

Vinyl wallpaper or coated paper restricts adhesion because of low porosity. Non-coated wallpaper is a superior foundation for high-end adhesives. Embossed or textured type of wallpaper can create uneven surfaces and jeopardise the final result of the new wallpaper.

Evaluating the Colour of Your Existing Wallpaper

Dark or vibrant layer of wallpaper can bleed through a new layer. A quick sample test clarifies coverage. Stripping ensures a uniform canvas if the old design shows through.

Determining the Number of Layers of Existing Wallpaper

• severely damaged
• textured
• coated or vinyl-based
• heavily pigmented

Steps to Wallpaper Over Old Wallpaper

Steps to wallpaper over existing wallpaper revolve around patient preparation and expert craftsmanship.

We conduct a full inspection if signs of peeling or discolouration appear

We remove bubbled areas with caution if compromised sections threaten adhesion

We fill cracks or small dents with a high-grade filler if a smooth finish is desired

We sand rough patches with 120-grit sandpaper if lumps disturb the refined aesthetic

We apply a premium primer if the existing wallpaper is embossed or saturated with dark colours

We use a deluxe adhesive for enhanced grip if the new wallpaper features thick textures or metallic accents

We align each strip meticulously if intricate patterns require absolute continuity

We trim excess edges with a sharp blade if crisp corners reinforce a flawless look

We allow 12 hours for the entire system to cure if ambient humidity is high

Required Materials:

Required materials for wallpaper over wallpaper installations rely on top-tier components that maintain a refined appearance. Our approach places equal emphasis on skilful technique and high-end products that deliver exquisite results.

• Select a premium primer engineered to seal patterned wallpaper if the underlying layer is dark or heavily printed.
• Select a professional-grade adhesive rated for heavier textures if the existing wallpaper includes vinyl sections.
• Select a wide smoothing brush with soft bristles (for example microfiber bristles) to eliminate air pockets on delicate finishes.
• Select a durable filler for minor cracks if any segments are flaking or peeling.
• Select high-quality sandpaper in 180-grit or 220-grit variants to achieve uniformity where raised edges exist.
• Select a precise trimming blade to address intricate pattern joints or detailed corners.
• Select a sturdy measuring tool that extends beyond 200 cm for full-length drops when working with taller walls.

1. Inspect Your Existing Wallpaper for Issues

We rely on our refined expertise to scrutinise every inch of the existing wallpaper. We acknowledge that discerning any flaws is critical to a flawless final aesthetic. We check corners, seams and edges for loose sections or minor tears. We explore 3 random areas for signs of moisture infiltration. We rely on a high-grade device to confirm dryness. We remove compromised panels if the damage is beyond minor to maintain a smooth base for the next layer.

2. Secure the Seams of Your Existing Wallpaper

We regard each seam as a vital detail if exquisite results are expected. We inspect every edge to reveal any signs of curling or raised corners. We remove stray fragments of old adhesive and lightly sand overlapping sections to achieve a uniform base. We confirm dryness by referencing moisture readings from an accredited device if there are traces of dampness. We then prepare a professional-grade adhesive for delicate sections that exhibit minor peeling.

1. Examine each seam for visible lifting or small gaps.

2. Apply a refined adhesive layer beneath loosened edges.

3. Use a high-quality smoothing roller to press the seam flat.

4. Secure edges for 12 hours if a stable bond is desired.

5. Refine residual imperfections with durable filler once the adhesive sets.

We rely on expert-tested materials recommended by renowned design institutions for consistent adhesion. We preserve the wallpaper’s original artistry by handling every corner with skill. Our careful method safeguards the existing layer and paves the way for a seamless new design.

3. Apply Filler to Your Existing Wallpaper

Apply filler to your existing wallpaper for a refined finish. We identify subtle dents or cracks and choose a premium compound that aligns with the wallpaper's composition. We mix the filler slowly for a uniform consistency. We spread the material with a flexible blade and we apply slight pressure to ensure a smooth plane. We rely on bright lighting to confirm even coverage and we wait for the filler to cure.

• Inspect each crease or hole if depth is more than 2 mm

• Stir the filler thoroughly to prevent lumps

• Spread thin layers if the wallpaper is delicate

• Sand each patch with a fine grade paper for a sleek result

4. Clean the Walls Thoroughly

Clean the walls thoroughly to remove dust, old adhesive remnants, and any surface residue that compromises a refined wallpaper application. We apply a premium cleaning solution using a soft sponge, ensuring every corner and edge is free of grime. Persistent marks (like grease spots) respond effectively to a pH-neutral detergent or TSP-based mix. Excess moisture dissipates fully if the area remains undisturbed for 12 hours in a ventilated environment. .

5. Applying New Wallpaper

 Luxurious results emerge when each strip lies flawlessly over the prepared surface. When executed carefully, layering on top of existing wallpaper preserves the underlying décor.

• Measure each panel against the wall for a perfect fit.

• Apply premium adhesive along the backside of the wallpaper for a secure bond.

• Align each strip from ceiling to skirting in small increments for superior accuracy.

• Smooth the surface with a wide smoothing brush to remove any air pockets.

• Trim excess edges along corners with a fresh blade for a refined outline.

• Maintain stable conditions in the room for 12 hours to aid the curing process.

6. Touch Up Your Painted Walls if Necessary

• Examine surfaces (corners, baseboards) for chipped paint or faint colour shifts.

• Sand rough patches with 180-grit paper for uniformity, if marks extend beyond 2 mm.

• Prime discoloured spots with a premium sealer, if deeper hues continue to show.

• Apply 2 coats of high-end paint (eggshell or matte) for refined coverage.

• Maintain an even motion with a quality roller or brush, if a textured appearance is desirable.

• Reserve 8 hours for drying between coats to bolster durability.

• Assess each section under focused lighting, and proceed with another coat if the underlayer is still visible.
