Hanging a Heavy Picture on Drywall | Pro Techniques & Secure Tips
11 October 2025 · 8 min read · by Walensky
Are you looking for the ideal solution to securely hang your pictures on a concrete wall? Whether you are an art lover, an interior designer, or a homeowner concerned about preserving their walls, choosing the right concrete anchors is crucial to support pictures weighing up to 20kg. In this complete guide, we explore the best fixings for concrete walls, from expansion anchors to chemical anchoring solutions, to help you install your artwork safely.
Understanding the Challenges of Concrete Wall Fixings
Hanging a picture on a concrete wall presents a specific challenge compared to drywall or wood walls. Concrete, due to its density and strength, requires adapted fixing systems that can penetrate and anchor firmly into this hard material while supporting the weight of your artwork without damaging it.
- Concrete is an extremely dense and resistant material to penetration
- Concrete walls transmit little vibration, requiring a solid anchorage
- Inappropriate fixings can damage your wall or fail to hold the load
- The weight of a 20kg picture requires a reliable long-term fixing
Key point to remember: For a 20kg picture on concrete, never use simple nails or standard plastic anchors - they are not designed for this type of load and could cause your artwork to fall.
Types of Concrete Anchors Suitable for Heavy Pictures
Expansion Anchors for Concrete
Expansion anchors are among the most common solutions for fixing medium-weight pictures on concrete. Their operation is based on an expansion mechanism that creates pressure against the walls of the hole once the screw is inserted, ensuring a solid anchorage.
Pro tip: For an expansion anchor, always drill a hole slightly deeper than the length of the anchor itself (about 1cm more). This will allow the concrete dust to settle at the bottom without hindering the complete insertion of your fixing.
Hammer-in Metallic Anchors
These anchors are particularly suitable for medium loads such as a 20kg picture. They consist of a metallic sleeve with a collar and a central nail. Once the nail is hammered in, the sleeve expands and creates a powerful anchorage in the concrete, ideal for valuable works of art.
Chemical Fixings for Concrete
Chemical anchoring offers a premium solution for hanging heavy paintings on concrete. It uses a resin that, once injected into the drilled hole, solidifies around a threaded rod to create an extremely strong anchor, perfect for valuable works of art.
- The resin chemically bonds to the concrete for superior strength
- This solution easily supports loads exceeding 20kg
- It offers exceptional resistance to vibrations
Self-Drilling Concrete Wall Plugs
Self-drilling anchors have the advantage of not requiring prior drilling, which can be an asset for quick installations. However, they are generally less recommended for heavy loads such as a 20kg painting, unless they are specifically designed for this purpose.
| Plug Type | Maximum Load | Ease of Installation | Approximate Price |
|---|---|---|---|
| Plastic Expansion Wall Plug | 10-15kg | Easy | 2-5€ (pack of 10) |
| Metal Hammer-in Wall Plug | 20-30kg | Medium | 8-12€ (pack of 10) |
| Chemical Anchoring | 50kg+ | Complex | 15-25€ (kit) |
| Self-Drilling Wall Plug | 10-20kg | Easy | 6-10€ (pack of 10) |
Criteria for Choosing a Concrete Fixing Suitable for Wall Art
The Exact Nature of Your Wall
Not all concretes are the same, and the choice of your wall plug must take into account the specifics of the material you are drilling.
- Solid concrete: Optimal for all types of wall plugs, allows the highest loads
- Cellular concrete: Requires specific wall plugs as it is more fragile
- Reinforced concrete: Be careful not to encounter metal reinforcement during drilling
The Exact Weight of the Artwork to be Hung
To accurately determine the necessary fixing, it is crucial to know the exact weight of your artwork.
- Artwork up to 10kg: Reinforced plastic wall plugs may be sufficient
- Artwork from 10 to 20kg: Opt for metal wall plugs or specialized anchors
The Distribution of the Load
An often-overlooked aspect is how the weight will be distributed across your fixings.
- Single centered fixing: The least recommended solution for 20kg
- Double horizontal fixing: Distributes the weight and improves stability
Important safety factor: For a valuable artwork weighing 20kg, always choose fixings rated for a higher load (minimum 30kg) to incorporate a safety margin to compensate for vibrations and wear over time.
Step-by-Step Guide: Installing a Fixing for a Picture on a Concrete Wall
Installing a fixing for a heavy picture on a concrete wall requires a methodical approach to ensure its solidity and durability. Here's how to proceed optimally:
- Choose the location and mark the point : Use a spirit level to ensure perfect horizontal alignment of your future installation
- Select the drill bit suitable for concrete : Opt for a concrete drill bit with the same diameter as your wall plug (never larger)
- Drill in percussion mode : Percussion is essential to effectively drill through the concrete without overheating the drill bit
- Carefully clean the hole : Remove dust with a blower or vacuum cleaner for optimal anchoring
- Insert the appropriate wall plug : For a 20kg picture, opt for a metal expansion wall plug or a chemical fixing
- Tighten gradually : Do not force the final tightening to avoid damaging the wall plug or the concrete
- Test the solidity before installation : Apply a force equivalent to the weight of the picture to check the resistance
Expert tip for chemical fixing: For optimal chemical fixing, strictly adhere to the drying time indicated by the manufacturer before applying a load. This time can vary from 30 minutes to 24 hours depending on the products and temperature and humidity conditions.
Common Problems and Solutions for Concrete Fixings
Even with the best anchors, some problems can occur when installing fixings for heavy paintings on concrete. Here's how to anticipate and resolve them:
Concrete Too Hard or Reinforced
If you encounter excessive resistance when drilling, you may have hit metal reinforcement. In this case, move the drilling point slightly by a few centimeters and start again.
Concrete Spalling
Cracking concrete around the hole often indicates poor quality or aged material. Opt for a chemical anchor to reinforce the area around the anchor point.
Plug Spins in Hole
This common issue signals a hole that is too large. The solution is to use a plug with a larger diameter or to partially fill the hole with a sealant before reinserting the plug.

FAQ on Concrete Wall Plugs for Paintings
No, standard plastic wall plugs are generally not suitable for a picture of this weight on concrete. For a 20kg picture, it is preferable to use metal expansion plugs, chemical fixings or specific anchoring systems that distribute the load over several points.
For optimal fixing in concrete, the drilling depth should generally be equal to the length of the wall plug plus 1 cm. For a 20kg picture, a minimum depth of 6 to 8 cm is recommended with a suitable wall plug. Remember to clean the hole carefully before inserting the wall plug.
Chemical fixing is not always essential for a 20kg picture on sound concrete, but it offers maximum safety, especially for valuable works of art. It is strongly recommended if the concrete shows signs of fragility, if you want a durable installation over time or if your picture is exposed to vibrations.
To repair a hole that is too large in concrete, you can use a fast-setting repair mortar or a bonding epoxy resin. Fill the hole completely, let it dry according to the manufacturer's instructions (usually 24 hours), then drill again to the correct size. For small holes, you can also use sulphur-free wooden matches or wooden toothpicks inserted with wood glue.
Conclusion: Choosing the Right Concrete Wall Plug for Your Picture
Installing a 20kg picture on a concrete wall requires a thoughtful approach and suitable fixings. Metal expansion wall plugs and chemical anchoring systems represent the best solutions to guarantee the safety of your work of art and the integrity of your wall.
Remember that the choice of fixing should take into account not only the current weight of the picture, but also a safety margin to ensure its stability over time. Investing in high-quality fixings is always worthwhile when it comes to protecting valuable works of art.
For particularly delicate installations or works of great value, do not hesitate to call a professional who will be able to advise you on the anchoring solutions best suited to your specific situation and carry out a perfect installation that will preserve your pictures and walls for many years.
