Sherwin-Williams Presentation

The learning for this week was about understanding paint in terms of more than just color. According to Paint, Specs & Color Resources by Sherwin-Williams, paint has three major purposes: protecting a substrate, enhancing aesthetics, and delivering advanced performance technology. Paint protects against the elements, corrosion, dirt, and moisture, while also using color and gloss to enhance design.


One of the concepts that were important to understand is that all paints are not the same. Paint is composed of four major parts: pigments, binders, liquids/solvents, and additives. Pigments are what give paint color and hide, binders are what give paint adhesion and durability, solvents are what help to apply the paint, and additives are what improve performance properties such as washability and mildew resistance.


The lecture also discusses the various kinds of coatings, such as alkyd (oil-based), latex (water-based), acrylic, epoxy, and urethane. For instance, latex paints are less smelly and have lower VOCs, whereas alkyd paints are smooth and durable but tend to yellow with time. Acrylic coatings are known for their strong adhesive and flexible properties, making them ideal for use both indoors and outdoors.

Another key area of discussion is painting sheen. Paint sheen is known to influence the durability of paint and its ability to reflect light. Flat paints are known to diffuse light and hide surface imperfections, whereas gloss paints are known to reflect more light and are the most durable. Paint sheen has a direct effect on the color appearance of a room.

The lecture also covered Light Reflectance Value (LRV), which is the measure of the amount of visible light a color reflects, ranging from 0 (black) to 100 (white). Dark colors with low LRV produce intimate spaces, while high LRV colors produce larger spaces. LRV is a useful design tool when choosing colors for spaces with different lighting conditions
.

In conclusion, the lessons covered this week have taught me that when it comes to paint, it is not just a matter of picking a color. There is so much more to it, including knowledge of pigments, durability, finish, lighting conditions, environmental regulations, and sustainability certifications.

    Ruth,
    Your summary of what our guest covered was comprehensive. It shows me that you learned a lot from our guest speaker. Their is much to consider when specifying a paint for a job. Your sketch was excellent! 50/50 points

INT 270 Ruth Hernandez   Blog 1  This weak   we talk about the importance of knowing all the basic elements that we can use to design for our future interiors...  First of all, of them was the POINT: ‘‘All pictorial form begins with the point that sets itself in motion...  The point moves... and the line comes into being—the first dimension. If the line shifts to form a plane, we obtain a two-dimensional element.  In the movement from plane to spaces, the clash of planes gives rise to body (three-dimensional) ... A summary of the kinetic energies which move the point into a line, the line into a plane, and the plane into a spatial dimension.”   Paul Klee,  The Thinking Eye: The Notebooks of Paul Klee (English translation) 1961. The point indicates a position in space. (C hing pg3.)  A point has no dimension, but it helps us to organize our surrounding elements and stabilizes them. Now, two points can define an axis, and helps to organiz...

INT 232 Ruth Hernandez week 9: Concept statement, and Diagrams This week, we look a number of new forms of drawings and project processes that are going to be useful as we continue the development of our container home designs. Although some of the concepts were familiar to me, there were others that were new and proved to help me better understand how to organize a space more effectively.  One concept that was familiar to me was the concept statement. This is a concept that I have used in the past on some projects, so it was comfortable to work with it again. This concept helps to ensure that the entire design is tied together by a single idea or vision.  Each of these concepts plays a significant part in the early stages of the design, especially in relation to the planning. Adjacency matrix is a tool that can be employed to plan and arrange the relationship between various rooms within a given space. This tool can be represented in a table format that indicates the level of...

  INT 270 Ruth Hernandez   Blog 3 Balance, unity, and harmony We learned how balance, unity, and harmony could affect our perception of the interior space. Balance, unity, and harmony can help designers create interior spaces that are comfortable, organized, and harmonious instead of chaotic or with disorder. In interior design, balance is described to be the distribution of visual weight in a given interior setting. It can be achieved by using elements such as symmetry, asymmetry, and radial pattern balance. When it comes to sketching, balance aids in moving the viewer’s eye in a particular interior setting, thus avoiding the appearance of one side of a setting as being heavier than the opposite side. Unity refers to all the elements within a space working together . Elements of unity within an environment are achieved by using the materials, colors, textures, and shapes consistently. When sketching an environment, repeating certain shapes or lines helps relate seeming...
