before painting your home,this is how to calculate amounts paints needed.


To calculating the amount of paint needed when you are about to paint a house or surface area depends largely on the dimension of the rooms or of the surface area of the wall.
The number of coats you should apply depends on the type of paint, the colour, the nature of the colour you are applying, method of application and the nature of the surface.


Steps Required

         i.            Get a measuring tape and Measure out the perimeter of the room. e.g. you measure out the entire length of the four sides of the room or as the case may be (The horizontal measurement).

       ii.            Then measure out the height of the room, the length from floor to the Ceiling. These could be in meters or in feet as desired (The vertical measurement)

      iii.            Now calculate the surface area of the room which is simply by multiplying the total length of the room (The horizontal measurement) by the ceiling height (The vertical measurement) but deducting the dimensions of windows and doors opening or as the case may be .standard Nigerian room, is usually 3.6m x3.6m or 12ft x12ft, 3.6m x3.0m or 12ft x 10ft depending on the design plan of the house.

     iv.            After this measure out the openings in the room, most often the windows and doors. For windows it may be 1.2m x 1.2m (4ft x 4ft) or 1.8m x 1.2m (6ft x 4ft).
The height of windows is mostly 1.2m or 4ft while the length is what usually varies. Multiply the height by the length of all the windows and then do same for doors. For doors the height is usually 2.1m or 7ft and the length is 0.9m or 900mm or 3ft do multiply the height by the length and sum the total areas of openings in the room then subtract from the total surface area of the room.

       v.            After determining your area (square feet or m2) then choose your paint check the label of the paint bucket for the spread rate for the paint. Spread rate is just the number of square feet (m2)of surface each coat of paint will cover .After finding out, divide the total surface area you measured earlier by this number to determine the number of paint bucket/liter you will need for each coat. The number of coats you should apply depends on the type of paint, the colour, the nature of the colour you are applying, method of application and the nature of the surface.

     vi.            Lastly you will likely need a second coat of paint when covering a dark color with a lighter one. Also, certain surfaces, like exterior masonry, are very porous and absorb a great deal of paint. In such cases, a second coat is often needed to give the paint a uniform appearance. Using a brush will put on a heavier, better-hiding coat than roller application.

Construction Procedure of Surface Road Side Drainage-PART 1 (with picture)

Surface water ( i.e., rain water) that falls on the ground surface such as; open field, paved areas or road surface, roof tops etc are channeled to a main drain naturally or through a constructed channel which is referred to as drainage. Procedure for construction of a common drainage (trench) (1m x 1m U drainage) (reinforced). includes; I.       Marking Of Alignment: The surveyor marked out the alignment for the trench to be dug. II.       Digging/Excavation: The surveyor marked out the dept of the trench to be excavated with a mechanical excavating machine. For a 1m x 1m drainage, the mathematical process of obtaining the required dept is to sum together the dept of the required drain + base + blinding. For dept:  A drain of dept1000 mm, base of 150 mm and blinding of 50 mm. Hence 1000mm + 150mm + 50mm = 1200mm (1.2 m) So an excavation of 1200mm (1.2m) is required from the to level of the road surface. For width:

  V.        Next step is laying of concrete base on the blinded surface and the positioned reinforcement. A concrete base of 150 mm is to be laid or cast on the blinded floor, concrete grade C20 of ratio 1:2:4 is allowed (See concrete grading and mix ratio). A guiding panel is placed into position to guild in the laying of the concrete base in order to achieve a uniformly alignment base edge, thickness and width, also to manage concrete material while pouring. The base is cast with the U shape reinforcement bottom in between the concrete base achieving concrete cover below and above.   VI.        After setting and drying of the concrete base, next is to position the side wall panel form work. The floor base is marked to give the required one meter (1000 mm) internal width where the panel will be positioned. The panel wall spacing is 100mm, and wall height of 1000mm (1 meter), the panel is lubricated, clipped and prepared to accept the Concrete.

Setting out of a building

A building is set out in order to accurately define the outline and width of the excavation and to determine the center line of the proposed building walls, so that construction according to the building professionals drawing (the architectural plan) plan can be transfer into the ground, this building process is called setting out of building. The center line method of setting out is generally preferred and adopted Setting out can be a very complex engineering process but with need experience its quite easy. Experienced engineer and surveyors are those involved in setting out of structures, in large projects, services of land surveyors are required for more accurate transfer of levels and angles in setting out with the aid of a Theodolite to decided point around the building area But we are going to concern ourselves with the most common setting out method ·          Setting out using pegging ·          Setting out using blocks. But here, we will be discussing
