Pain Points

Image-to-Wall Transfer Challenges

Transferring a small image to a large wall or canvas is inherently difficult. It requires the artist to maintain proportion and perspective over a much larger scale, often without any direct reference points.

Costly Techniques

Some methods of transferring images, such as using large sheets of paper as stencils, can be prohibitively expensive. This method, while detailed and effective, may not be financially viable for all artists or projects.

Equipment Requirements for Projector Use

Using a projector simplifies the transfer process but requires working in darkness, which can be impractical outdoors or in public spaces. Additionally, projectors and their maintenance can be expensive.

Paint Supply Management

Estimating the amount of paint needed for a large mural is complex. It often involves manual calculations and referencing manufacturer specifications to determine coverage, which can be time-consuming and inaccurate.

User Experience & Design

User Journey

This process involves scanning the chosen wall, selecting an image from the user’s phone, adjusting the image’s placement via the app, and, upon confirmation, using the phone as a guide to draw the image directly onto the wall.

This process allows graffiti artists and muralists to use the Wallz app to bring their digital creations to life with precision and ease, transforming plain surfaces into works of art.

This feature not only saves time and money for the artists but also promotes efficiency and sustainability by reducing waste. It’s an embodiment of Wallz’s commitment to supporting artists throughout the entire creative process, from conception to the final stroke.

You’ll Never Wallz Alone

Building on its suite of innovative features, Wallz introduces a collaborative element that transforms mural painting into a shared experience. With the app’s location-sharing capability, artists can invite friends to join in on a project by syncing with the scanned wall data. This means that multiple creators can simultaneously view the augmented reality projection of the image on the wall, allowing for a coordinated effort in bringing the mural to life. It’s a feature that not only fosters community and teamwork but also significantly expedites the painting process, as artists can work on different sections of the mural in harmony, guided by the precision of Wallz’s AR overlay.
