Cracked, patched and tired render repaired and re-finished, with the cause of the damage dealt with first so the repair is not a cosmetic cover-up.
Call Jimmy — 0432 077 782Hairline shrinkage cracks and larger movement cracks assessed separately, because they are not the same problem.
Damaged areas made good with the texture matched, so a repair does not show through the paint.
A textured coating that unifies a repaired wall and covers fine cracking.
Gutters, damp and failed flashings looked at before coating, so the problem does not return.
Jetblack Painting repairs and re-coats render across Melbourne, from fine cracking and patched sections to walls that need a uniform new finish. Render repair is mostly detective work: finding out why it cracked, lifted or stained, and fixing that before any coating goes on.

Fine, hairline cracking is common in cement render and usually comes from the render shrinking and moving with the seasons. It is mostly cosmetic and is usually filled and coated over.
Wider cracks, stepped cracks that follow the mortar joints, and cracks that open at the corners of windows and doors point to movement in the wall or the ground. Those need to be understood before they are filled, because a crack that is still moving will reopen through any repair. We say so at the quote instead of patching it and hoping.
Tap a rendered wall and a hollow, drummy sound means the render has come away from the wall behind it. Hollow render is not a cosmetic problem: it needs to be cut back to sound render before a patch goes on, and we tell you at the quote when an area is beyond a simple repair.
Patches also show for a simpler reason. Fresh render is a different texture and absorbs paint differently, so a smooth patch in a textured wall shows through the finished coat as a ghost. Matching the texture of the surrounding wall is much of the skill in a repair that disappears.
A textured coating is thicker than paint and builds a consistent finish over a wall that has been repaired in places. It also helps hide fine cracking and uneven patches.
On sound, dry cement render with fine seasonal cracking, a flexible coating that bridges cracks is often the right answer. On a wall with an ongoing moisture problem, or on soft lime-based render on an older home, a tight coating can trap water in the wall. Our article on painting rendered walls explains how to read the wall before choosing.
Render usually fails because of water: a leaking gutter or downpipe, a failed sill or flashing, garden beds or paving banked against the wall, or damp rising from the ground. Repairing and coating without dealing with that just gives the water a fresh surface to push off.
That is why we look at the gutters, sills and ground levels around a wall before talking about coatings, and why the order of work is: stop the water, let the wall dry, repair, then coat.
Fine hairline cracks usually can. Wider cracks, stepped cracks and cracks near windows and doors may be moving, and a moving crack comes back through a repair. We assess which kind you have before quoting.
Usually because the patch is a different texture from the wall around it, or because fresh render absorbs paint differently. Matching the texture and sealing the patch before painting stops it showing.
It means the render has come away from the wall behind it. That area has to be cut back to sound render before it is patched. A cosmetic filler over hollow render will not last.
A texture coating is thicker and builds a consistent surface over repaired or uneven render, and can cover fine cracking. Ordinary paint is thinner and follows the surface underneath, so it will show repairs more.
Most render with cracking or local damage can be repaired. Render that is hollow over large areas, or that is breaking down because of long-term damp, may need more than a repair. We tell you which at the quote.
Often, yes. Render on older homes can be softer and more lime-based, and it is designed to let moisture through. Sealing it under a tight modern coating can trap water and break it down, so the coating needs to suit the wall.
