1. Measure Walls: Start by measuring the length and height of each wall in the room. Use the measuring tape for accuracy.
2. Record Measurements: Write down each wall's length and height on your paper, labeling them accordingly (e.g., Wall 1, Wall 2, etc.).
3. Calculate Wall Area: To find the area of each wall, multiply the length of the wall by the height of the room. Measure the height from the floor to the ceiling, excluding any areas with windows or doors. Write down these measurements beside each wall length.
4. Calculate Total Wall Area: Add up the areas of all the walls in the room to find the total wall area. This will give you the total square footage of wall space that needs to be painted.
5. Deduct Windows and Doors: If there are windows or doors on any of the walls, subtract their areas from the total wall area. Measure the width and height of each window and door, and then multiply these dimensions to find their area. Subtract the total area of windows and doors from the total wall area.
6. Calculate Paint Needed: Determine how much paint you'll need by checking the paint can for coverage information. Most paint cans provide an estimated coverage area per gallon. Divide the total wall area (after deducting windows and doors) by the coverage area per gallon to determine how many gallons of paint you'll need.
7. Consider Additional Factors: If you're repainting with a different color or type of paint, you may need additional coats for proper coverage. Factor this into your paint calculation.

1. How to make bleaching solution:  Eliminate mold and mildew: Mix 1 part bleach with 3 parts water. Rinse well and let dry.

2. To etch smooth GI sheet for an anchor profile and to neutralize its alkalinity: Use vinegar.

3. To etch smooth cement flooring for better adhesion: Treat with a 1:1 muriatic acid and water solution. Rinse thoroughly and let dry.

4. To eliminate odors from latex paint: Place a basin of water with vinegar in the center of the room.

5. To eliminate the paint smell from alkyd enamels: Place containers of charcoal around the room.

6. To check if concrete is dry enough for painting with solvent paints (but not alkyd enamel) to prevent
blistering: Tape a small piece of plastic to the surface and leave it for 24 hours. If no moisture sweats underneath, the concrete is dry enough.

7. For even sanding do not only use hands, use a sanding block

1. Clean walls and trim

2. Remove grime, cobwebs, dust and stains that can prevent your paint from adhering.

3. Use a mixture of lukewarm water and mild soap, gently rubbing in a circular motion.

4. Rinse your walls using a slightly damp cellulose sponge.

1. Remove all movable furniture in the room, if not possible to move cover it, and vehicles if painting outside to prevent accidental splatters.

2. Cover with newspaper & tape all immovable objects, including switch plate covers, ceiling fan bases, door jambs, door knobs etc.

3. Provide drop cloths or plastic sheeting on floors for easy cleanup.

By taking these preparatory steps, you create a clean and organized workspace conducive to painting, ensuring better results and minimizing the risk of damage to surrounding objects
