To calculate the square meters of a wall, you need to measure the length and height of the wall in meters. Then, multiply the length by the height to get the total square meters. For example, if a wall is 4 meters long and 3 meters high, the calculation would be 4 meters x 3 meters = 12 square meters. This will give you the total area of the wall in square meters. **

To mount square timber on the wall, you can use a few different methods. One option is to use L-brackets to secure the timber to the wall, making sure to use anchors if the wall is drywall. Another option is to use a French cleat system, which involves attaching one piece of the cleat to the wall and the other to the timber, allowing for easy hanging and removal. You can also use wood screws to directly attach the timber to the wall, making sure to pre-drill holes to prevent splitting. Whichever method you choose, be sure to use a level to ensure the timber is mounted straight and securely. **

The amount of white wall paint needed for 83 square meters will depend on the coverage of the paint. On average, one liter of paint can cover around 10 square meters with one coat. Therefore, for 83 square meters, you would need approximately 8.3 liters of white wall paint for one coat. It is recommended to apply two coats for better coverage, so you may need around 16.6 liters of paint in total. **

The amount of wall paint needed for 12 square meters depends on the coverage of the paint. Typically, one liter of paint can cover around 10-12 square meters with one coat. Therefore, for 12 square meters, approximately 1 liter of wall paint would be needed. It is always recommended to check the specific coverage information provided by the paint manufacturer to ensure accurate coverage. **

The cost of wall plaster and screed per square meter can vary depending on factors such as the type of material used, the complexity of the job, and the location. On average, the cost can range from $15 to $30 per square meter for wall plaster and $20 to $40 per square meter for screed. It is recommended to get quotes from multiple contractors to get a more accurate estimate for your specific project. **

The amount of wall paint needed for 1739 square meters will depend on the coverage of the paint. Typically, one liter of paint can cover around 10-12 square meters with a single coat. Therefore, for 1739 square meters, approximately 145-174 liters of wall paint will be needed. It's important to consider the specific coverage of the paint being used and any additional coats that may be required for an accurate estimate. **

The approximate cost for wall plaster is around $10 to $20 per square meter, depending on the type of plaster and the complexity of the job. For floor screed, the cost is typically between $15 to $30 per square meter, again depending on the type of screed and the specific requirements of the project. These costs can vary based on factors such as location, materials used, and the complexity of the job. It's always best to get a few quotes from different contractors to get an accurate estimate for your specific project. **

An experienced man should be able to tile 11 square meters of wall in approximately 1-2 days. This time frame allows for proper preparation, measuring, cutting, and installation of the tiles. However, the exact time may vary depending on the complexity of the tiling job, the type of tiles being used, and the individual's level of expertise and efficiency. **
