bonding agent or mortar composed of fine aggregate and cement.

rendered all the time while materials like stone and brick don't need rendering

Things
to Consider
In
terms of external rendering, there are things to be taken into account
including the kind of base material or substrate, the exposure level to rain
and wind and the finished exterior's desired look. In turn, such factors will
dictate the render's composition and the coats that you should apply.
Before
you apply a render to your wall, you need to keep in mind some things. For
repairing decayed render, it is important to brush off the wall so that any
loose material will be removed. After this, you can bond the external render
properly to your wall. This also depends on the kind of wall finish you have.
You can observe that while the water in a number of external renders
evaporates, the latter will shrink. You can avoid this if you ensure that your
wall is wetted properly beforehand and the coats applied are one-half inch
thick. This is helpful in drying the mix sooner. The wall's deep hollows can be
covered up using small tile bits. The mortar should be dry before the
application of the first coat. After doing the fairly thin coat, you can apply
subsequent coats using a trowel. The mortar will begin to have cracks when it
is drying up. You should make sure that the cracks are caused by the shrinking
process instead of the breakdown of the previous coat.
