Tips to easily paint your house…


Α. Calculation of painting surface

  • Length x wall height = A
  • Subtract the openings (doors, windows) length x height = B
  • A-B painting surface
  • Ceiling surface length x room width
  • Required paint quantity: painting surface / paint performance (hiding power) = paint quantity
  • Paint quantity x number of coats required for the final quantity

Β. Surface preparation before painting

  • Walls with cracks: use the tip of the spatula to open a larger crack and dust off the residue with a brush. Then dull with the appropriate putty and sandpaper the surface. Prime with an ecological primer.
  • Cracked – peeled walls : peel off the protruding pieces, sand with sandpaper, dust off the residue and where necessary, touch up.
  • Old walls with oil paint: soap the surface, rinse and let dry. Then sand with sandpaper, dust the surface and prime with a suitable ecological primer.
  • Old water-painted walls: prime before painting with an ecological primer.

Γ. Preparation materials – tools:

  • Paper tape
  • Absorbent sponge for cleaning surfaces
  • Audoule or nylon paper
  • Sandpaper
  • Spatulas for trimming
  • Painting boats for even spreading of the paint
  • Depending on the final result and the type of colour you will need corresponding brushes and rollers. In more detail:
  • For corners and anything embossed, you will need a round brush
  • For larger surfaces, such as skirting boards and doors, you will need a regular brush with long bristles
  • For difficult surfaces, such as radiators, you will need a long crooked nail or roller suitable for radiators
  • If you paint with varnishes or glossy paints, you will need a short hair roller
  • If you paint with satin or matte colours, you will need a medium hair roller
  • If you want a grained (embossed) effect, you will need a long hair roller or a roller suitable for relief colours.
  • To spread the paint evenly on the roll, use a paint tray

Δ. Painting process:

  • Start from the roof (ceiling). Make perimeter ‘cuts’ with a long-bristled brush.
  • Avoid ‘runs’ on vertical walls by applying paper tape to the top of the walls.
  • Continue on the surface with the roller, painting in the direction of the light (from the openings to the inside). The colour you use with the roller should be less ‘diluted’ than the one you applied to the ‘cuts’.
  • For a perfect application, paint per m2 crossing the passages.
  • Continuing on the walls, start painting from the middle of the wall, spreading the paint up and down.
  • On a wall where you are applying two-tone paint, separate the surfaces with masking tape. Remove it immediately after painting and before the paint dries.
  • Finally paint doors, windows, radiators and skirting boards
  • Painting of openings:
  • Windows: paint the frame from the outside inwards. Continue with the case and finish with the sides. When the paint is still wet, be careful not to close the windows.
  • Doors: start from the corners, continue painting from top to bottom.

Ε. Tips:

  • A clever choice of colour can transform the feel of a space in relation to its actual dimensions.
  • To ‘elevate’ a low-ceilinged space, apply vertical stripes or bright white paint.
  • To ‘lower’ a taller room, choose darker shades on the walls and a darker shade on the ceiling. Divide the wall surface into two parts, horizontally, and apply different shades. Paint the first 10-15cm at the top of the wall in the same colour as the ceiling
  • To ‘enlarge’ a space, choose light shades, avoid stark contrasts or paint a landscape on a wall.
  • To ‘widen’ a narrow and long space, paint the large surfaces light and the narrow ones dark.
  • To ‘narrow’ a space, follow the exact opposite logic.
  • To ‘shrink’ a space, apply dark/hot shades and large contrasts in colour. Create a large window and paint it in a shade that contrasts strongly with the rest of the room.
  • Exterior walls: when choosing a shade, be aware that under sunlight it will look lighter. So choose a darker shade. In contrast, in shade or in the absence of plenty of sunlight, a shade will look darker or grayer. So choose a more open one.

F. Basic requirements of a quality paint:

  • Coverage
  • Version
  • Whiteness
  • Application properties
  • Mechanical strengths
  • Shade stability
  • Resistance to time
  • Stable quality

Ζ. additional exterior color properties:

  • Resistance to weather and UV radiation
  • Preservation of the vividness of the shades
  • Not to burst or peel
  • To breathe
  • To keep its whiteness or shades unchanged
  • Have an aesthetically acceptable perfect finish
  • To have stable quality

Η. What to look out for:

  • Don’t stop by leaving the wall unpainted
  • Avoid ‘runs’ by lightly dipping your brushes into the paint
  • Do not second hand a surface that is not fully dry.
  • Do not work with open radiators. Protect the surface from air currents, which can cause uneven drying
  • Some darker shades may require more layers for full coverage. To reduce costs and avoid multiple layers, we recommend using as a first layer a lighter shade of the same colour family produced from a more opaque base or, alternatively, a medium grey shade. A grey primer helps if the surface has not been primed.
