Liquid wallpaper on whitewash: types, tips, and step-by-step application

What can be done with whitewashed walls?

Whitewashed walls are one of the simplest and most affordable finishing options, especially if you have a limited budget or want to add a touch of traditional charm to your home. However, over time, the whitewashed surface can crack, flake, or simply become boring with its monochromatic appearance. The question arises: what to do with whitewashed walls to make them look modern and attractive?

1. Repaint with special paint
   If the walls are not seriously damaged, sometimes it is enough to refresh them with paint. However, whitewash is extremely “capricious” — it has a porous structure that complicates adhesion with other materials. Therefore, it often requires filling or priming.

2. Apply wallpaper (traditional or liquid)
   In many cases, applying wallpaper over whitewash without additional preparation is risky. However, you can choose the right type of wallpaper (for example, liquid or non-woven) and properly treat the wall. This method can quickly and effectively update the interior.

3. Decorate the wall with decorative plaster
   Decorative plaster, especially with a concrete or marble effect, is a great option for modern styles like “loft” or “minimalism.” But the whitewashed surface will still need to be reinforced by removing weak spots and applying a special primer.

4. Apply liquid wallpaper
   This is a more modern way to transform whitewashed walls into a “highlight” of your interior. Liquid wallpaper creates a unique texture, hides imperfections, and can become an original accent in the room.

Below, we will take a closer look at the features of liquid wallpaper and the possibility of applying it over whitewash.

Liquid wallpaper (liquid wallpaper): what is it?

Composition and characteristics

• Liquid wallpaper (also known as “liquid wallpaper” or “decorative plaster”) is a mixture of cellulose, textile fibers (silk, cotton, etc.), an adhesive component, and dyes.
• Supplied in the form of a dry mixture or already prepared paste. Before use, it often needs to be mixed with water (according to the manufacturer’s instructions).
• Applied with a spatula, trowel, or roller. As a result, you get a seamless covering with an interesting texture.

Types of liquid wallpaper

Depending on the composition and decorative additives, liquid wallpaper can be divided into:

1. Cellulose — with the highest cellulose content, a fairly budget option.
2. Silk — more expensive, characterized by a “silky” sheen and high durability.
3. Silk-cellulose (mixed) — an optimal combination of price and quality.
4. With mineral additives — contain mica, quartz, or stone chips to create a shimmering or “stone” effect.

Advantages of liquid wallpaper

• Mask imperfections and small cracks due to their thickness and density.
• Improve thermal and sound insulation of the room.
• Easy to repair: you can remove the damaged area by soaking it with water and apply a new layer.
• Have a wide selection of colors and textures, allowing for design experimentation.

Disadvantages of liquid wallpaper

• Higher price compared to most traditional finishing options.
• Need for careful maintenance: excessive rubbing or use of abrasive agents can damage the covering.
• Professional application: it is more difficult for a novice to achieve an even texture on the first try.

Whitewashing walls: a brief overview

What is whitewashing and its types

• Whitewashing is a mixture based on lime (or chalk), water, and sometimes additional pigments.
• Often used in utility rooms, in rural areas, and to give walls a pleasant light appearance.
• Usually produced in the form of lime, chalk, or casein solution.

Advantages and disadvantages of whitewashing

• Pros: eco-friendly, affordable, provides “breathability” to walls (allows moisture to pass), and reflects light well, brightening the room.
• Cons: wears out quickly (cracks, flaking), limited color selection, often requires regular updating, and does not always have good adhesion with other materials.

Whitewashing in different colors

Although the classic color of whitewash is white, today there are pigmented options available. However, overall the selection of shades is not as wide as that of paints or liquid wallpapers.

Can liquid wallpaper be applied over whitewash?

The key question is: can liquid wallpaper be applied over whitewash without serious adhesion and durability issues? The answer is yes, it can, provided the surface is properly prepared.

Main compatibility conditions

1. Clean, solid surface
   The whitewash should not be flaking or peeling. If there are cracks or areas that are coming off, they need to be removed and filled.

2. Reduce porosity
   Lime whitewash has high porosity, which can reduce adhesion. Therefore, before applying liquid wallpaper, it is advisable to use a special primer (preferably deep-penetrating) that will enhance strength and adhesion.

3. Complete drying
   Make sure the whitewashed wall is completely dry. Moisture or dampness will lead to mold growth under the layer of liquid wallpaper and premature peeling of the covering.

How to apply liquid wallpaper over whitewash: step-by-step instructions

1. Check and prepare the walls

1. Inspect the walls: scrape off any flaking whitewash, smooth out cracks and holes with filler.
2. Remove dust and dirt: wipe with a damp cloth or brush.
3. Apply filler if necessary where there are significant unevenness.

2. Priming

• Use a deep-penetrating primer, and if the whitewashed layer is very “weak” — a special strengthening primer for lime surfaces.
• Wait for complete drying (usually 6–12 hours, depending on the composition).

3. Preparing liquid wallpaper

• Mix the dry mixture with clean water in the proportions specified by the manufacturer.
• Stir thoroughly to avoid lumps.
• Let the mixture “swell” (usually 12 hours) — this will improve its plasticity.

4. Applying liquid wallpaper

1. Start from a corner or the least noticeable area.
2. Apply the mixture with a spatula, trowel, or roller in an even layer (1–2 mm).
3. Smooth out with movements in one direction, avoiding sharp thickness variations.
4. If necessary, additionally “smooth” with a damp spatula to achieve the desired texture.
5. Leave the covering to dry completely (depending on the manufacturer, usually 24–48 hours).

5. Finishing touches

• If desired, you can apply a protective varnish or wax (some brands of liquid wallpaper allow this).
• Make sure to follow the manufacturer’s instructions for care and use.

Pros and cons of liquid wallpaper on whitewash

Advantages

1. Increased durability
   Liquid wallpaper forms an additional protective layer, shielding against dirt and moisture.
2. Hiding imperfections
   The thick layer of material smooths out small irregularities and cracks.
3. Aesthetic uniqueness
   A texture that is not available with traditional paint or regular wallpaper.

Disadvantages

1. Difficulty of application
   Certain skills are needed; otherwise, unevenness or stripes may occur.
2. May poorly adhere to weak whitewash
   If the layer of whitewash is not reinforced or areas of peeling are not removed, the covering will quickly come off.
3. Price
   Quality liquid wallpaper often costs more than other finishing options.

Frequently Asked Questions (FAQ)

Can liquid wallpaper be applied to clay?

Yes, it can, if the clay surface is strong enough, dry, and primed with the appropriate agent. Clay, like whitewash, is quite a porous material, so without a quality primer, adhesion issues may arise.

How to apply liquid wallpaper on plaster?

The technology is the same: clean the plaster from dust and dirt, prime with a deep-penetrating compound, wait for drying, and apply liquid wallpaper. If the plaster has cracks or unevenness, level it beforehand.

Can liquid wallpaper be painted?

Some types of liquid wallpaper can be painted with acrylic or water-based paints, but usually, the original texture of the covering is lost. If you want to change the color, it is better to remove the top layer (by soaking it with water) and apply a new mixture.

Can wallpaper be applied over whitewash without priming?

Theoretically yes, but it is not recommended. Without priming or preparation, there is a risk of the wallpaper peeling off within a few months. This is especially true for liquid wallpaper, which requires reliable adhesion to the surface.

Which liquid wallpaper is better?

It all depends on the budget, desired texture, and operating conditions. Silk liquid wallpaper is considered the most durable and elegant. Cellulose is cheaper but less durable. Often, mixed silk-cellulose options become the optimal choice.

Liquid wallpaper: pros and cons in one line

• Pros: mask wall imperfections, improve insulation, create original designs, and are easy to repair.
• Cons: more expensive than regular paint or wallpaper; require care during application; do not tolerate heavy wet cleaning.

Conclusion

Applying liquid wallpaper on whitewashed walls is a completely feasible task that allows for a quick and effective interior update. The main thing is to properly prepare the surface: remove weak areas, definitely use a primer, and wait for complete drying. Although this requires some effort and expense, the result in the form of a unique texture, additional thermal insulation, and attractive design fully justifies the effort.

If you doubt your skills, consult professionals. However, by following the instructions and applying a bit of patience, you can transform whitewashed walls into modern and stylish surfaces on your own. This is a great opportunity to refresh your home and add comfort and individuality.
