Painting with Portland

 So I've decided to paint the existing driveways and walkways around the MOAM abode with paint made from Portland Cement for a white washed effect.  In certain areas, I will be laying tile down in random fashion from tiles left over from various jobs.  I have 100 sq ft or so taking up space in my supply shed.

Don't worry, I'll put down some before and after shots just in case you want your walkways to look as cool as the MOAM's.

Here is the MOP.  (Method of Operation for those of you who are not PMP's.)

Portland cement is typically not used as a primary ingredient in paint because it is a fine powder that, when mixed with water, hardens into a solid structure. Instead, paint is made using a different set of ingredients, such as pigments, binders, solvents, and additives. However, Portland cement can be used to make a type of paint called "cement paint" or "whitewash," which is often used for coating masonry surfaces like walls and fences. Here's a basic recipe for making cement paint:

Ingredients:

  1. Portland Cement: You will need Portland cement, which is commonly available at hardware stores.
  2. Water: You'll use water to mix with the cement to create a paintable consistency.
  3. Lime (optional): Adding lime can help improve the workability and adhesion of the cement paint.

Instructions:

  1. Safety Precautions: Always wear appropriate safety gear, including gloves and eye protection, when working with cement and other materials.

  2. Mixing: To make cement paint, mix Portland cement and water in a ratio of about 1 part cement to 1 part water. You can adjust the ratio slightly to achieve the desired consistency. Add lime if desired, but it's optional.

  3. Stir Thoroughly: Use a mixing tool, like a stir stick or a drill with a paddle attachment, to thoroughly blend the cement and water. Continue mixing until you achieve a smooth and consistent paste-like consistency.

  4. Application: Apply the cement paint to the masonry surface using a brush or a roller. Make sure the surface is clean and free of dust, dirt, and loose particles before applying the paint. Multiple coats may be needed for proper coverage and protection.

  5. Drying: Allow the cement paint to dry. The drying time may vary depending on environmental conditions, but it typically takes a few hours to a day for the paint to set.

  6. Additional Coats (Optional): If needed, you can apply additional coats to achieve the desired finish and level of protection.

It's important to note that cement paint is different from traditional paints in terms of appearance and application. It tends to have a rough texture and is typically used for functional purposes, such as providing a protective coating for masonry surfaces. It is not suitable for painting on surfaces like wood or metal, which require different types of paint.
