Final Image

Abstract[edit | edit source]

The objective of this project was to design and construct a mural to be installed on the library circulation desk at Zane Middle School. This page will discuss the background and criteria the project group utilized to create their design and the prototyping conducted to finalize the product plans. Included are the directions to replicate a similar style mural and to maintain or replace it. There are details for Zane Middle School to hopefully create and install more murals themselves.

Background[edit | edit source]

The circulation desk at Zane Middle School's library

Zane Middle School in Eureka, California has a library circulation desk that is fairly plain and empty. The school wanted an artistic piece that could be mounted to the front of this desk to bring an element of color and excitement into the space. Nancy Walsh, the Librarian at the school provided recommendations for the art itself while the team focused more of the research on creating a mural that was durable and safe. The team worked to design a secure low-profile panel that would act as the backing for the painting itself, while also finalizing the art that would be painted onto it.

Problem statement and criteria[edit | edit source]

The top priorities for this mural are the durability and safety since it is in a space where children will be leaning against frequently. Other criteria were set for ease in construction and maintenance as well as overall appearance.

Criteria Weight (out of 10)
Durability 9
Safety 9
Environmental Integrity 7
Portability 6
Aesthetics 5
Cost 5
Removability 5

Description of final project[edit | edit source]

The final design is comprised of a wooden substrate, mounted by nuts and bolts, and painted with acrylic paint. The wood is 1/4" thick birch wood, which is thin enough to not protrude over the existing desk top. The acrylic will be painted over a primer and treated with a finish for both durability and cleanliness. There will be a nut and bolt in each corner of the mural, connecting the panel to the face of the desk.

Testing Results[edit | edit source]

At this time the mural has not been tested in its full effect since the group has not been able to install it yet. The client expressed great satisfaction with the painting itself as it fit her desire for an inspirational reading-related theme. Many other individuals who have seen the painting also react positively to it and think it will fit perfectly in a library setting. Additionally, our client was in close contact while deciding materials and she agreed strongly with our choices to make it the most durable and safe. The mural will be installed at Zane in August 2020.

How to Build[edit | edit source]

Instructions:

1
[[File:|thumb|b]]
Locate mounting surface (should have an accessible back) and take dimensions. Decide how much of a border the mural should have and subtract that from the surface dimensions to get the panel size.
2
[[File:|thumb|b]]
Obtain, measure and cut the wood to the desired size, or order wood with the desired dimensions. Dimensions of completed center panel: 32.5" x 54.75". Dimensions of left panel: 32.5" x 49.5". Dimensions of right panel: 32.5" x 45.5". *These are the dimensions that the panels would be, already accounting for the 2" border from the desk.*
3
[[File:|thumb|b]]
Sand all edges, and face of wood until smooth to prep wood for painting. Dust off the sawdust from sanded surfaces using a non-abrasive material.
4
[[File:|thumb|b]]
Paint on a primer onto the sanded wood face. First in the direction of the grain of the wood, then in a perpendicular direction once the first layer dries.
5
[[File:|thumb|b]]
Draw a grid on the dry primed surface for each design to obtain correct proportions of the painting. Then sketch each component. Other options include freehand, projector, etc.
6
[[File:|thumb|b]]
Paint the mural design over the sketch using desired paints and brushes. Use a technique that best fits the project.
7
Apply a glaze finish over the complete and dry painting.
8
Once the glaze is dry, measure from each corner the position that the bolt will be placed. Mark these spots with a pen and then proceed to drill holes in each spot using a drill bit with the same diameter of the bolts that will be used.
9
Measure and mark the mounting surface where the bolts will be installed. Drill using the same drill bit diameter used on the wood.
10
[[File:|thumb|b]]
Mount the mural in place by inserting bolts through pre-drilled holes in both mural and the mounting surface. Slide washers onto the backside of the bolt until they are flush against the mounting surface. Screw the nuts onto the bolts and tighten by hand. Use a wrench to tighten nuts further so the panel is firmly secure.

Maintenance[edit | edit source]

This section will cover how to update the mural when the art would like to be replaced.

Schedule[edit | edit source]

When desired
  • Remove the mural
  • Paint over the existing design
  • Attach the mural

Instructions[edit | edit source]

The following instructions detail how to detach and reattach the panel.

Task Instructions
Detaching the Panel With a wrench, unscrew all four nuts from the back of the bolts. Then, remove the bolts from their holes.
Reattaching the Panel Line up the holes on the panel with the holes on the desk. Insert the bolts into the holes. Insert the washers onto the back of the bolts, then screw on the nuts with your fingers. Then, with a wrench, tighten the nuts.

Troubleshooting[edit | edit source]

Problem Suggestion
Loose Nut A wrench that fits snugly around the nut can be used to retighten the nut.
Warping of Plywood Add more bolts to further secure the panel on the desk.

Discussion and next steps[edit | edit source]

Due to the COVID-19 pandemic, only one panel was constructed. Originally, three panels were going to be constructed corresponding to the three sides of the desk. The "How To Build" section includes dimensions for the panels that would attach to the left and right faces of the desk. By referencing this section, panels for the remaining two sides of the desk can be constructed.

Suggestions for future changes[edit | edit source]

To promote student involvement, the mural panel was made to be easily removable. Therefore, Zane Middle School is encouraged to remove and update the art if they desire too. The process of attaching and reattaching the mural is covered in the "Maintenance" Section.
