HAIR CRACKS
These are very fine cracks appearing on surfaces of bare or previously painted
plaster and cement rendering. When the surface is painted or repainted still the
cracks will often show through the new paint. As by definition the cracks are only
as thick as hair they cannot be filled up or stopped as larger cracks can.
On external surfaces, extensive hair cracking of previously painted surfaces may
indicate a deterioration of the paint to an extent that requires complete removal
back to the substrate.
Painting:
(Over coating)
Exterior: 
One coat Tartaruga.
Interior:   
In extreme cases remove plaster, re-plaster and then 
                                                 follow normal painting for interior walls.

structure and are durable. A clear coat often enhances aesthetic appeal.
Surface Preparation:

the wood is dry and free from contaminant. Dust off thoroughly. All nails, pins
and screw-heads must be sunk well below the surface. If tacky or oily matter still
persists, wipe over with T-6.

HIGHWAYS
Highways are normally bitumen carpeted. It may also be made of concrete, For
bitumen carpeted road quality of bitumen should be such that it does not melt at
temp around 40
C and should not absorb much water to a point of disintegration
under pressure. During road construction necessary compaction is also
important.
Surface Preparation:
Clear all dusts, sand particles or other contaminants.
Painting: Apply 2 coats of Jensolin Road Marking paint
