CRAKGON surface repair
CRAKGON makes big commercial projects seem small. Paint it on and the cracks are gone!
What is it?
CRAKGON is a world-class product. It has been specifically designed and developed as a paint reinforcer to permanently repair surface damage both internally and externally. Most importantly it’s easy to apply, you simply paint it on and the cracks are gone.
What do you use it for?
CRAKGON is a problem solver product. Used to repair damaged surfaces it protects the wall and paint system against UV and weathering effects. It also strengthens the wall coating and dimensional stability to paint film. CRAKGON has been successfully used to eliminate the most common interior and exterior surface problems including:
- Any surface cracks, alligatoring and checking
- Rising Damp, Mould and Mildew
- Cement rendered walls and fences
- Blistering paint EG: Flaking fascia boards
- Cracked lathe and plaster walls and ceilings
- Sagging or Running
- Rust Discolouration
- Peeling paint due to poor adhesion, interior or exterior moisture.
We applied CRAKGON to repair a badly damaged plaster wall 8 years ago, we returned to do other work on the site recently and found that the repaired wall was in perfect condition but the walls surrounding the repair site were now covered in cracks.

How does it work?
CRAKGON works with non-woven paint reinforcing tissue of randomly dispersed continuous C-glass fibers. The glass fibers function like the “steel-rod grid in concrete structures”, enhancing the durability and, thus preventing cracking of the reinforced paint system. A single layer of CRAKGON® and paint offer an impermeable, highly abrasion resistant, hygienic and long lasting protection barrier. Which, most importantly allows the wall to breathe.
CRAKGON® REINFORCED PAINT JOB
The CRAKGON® system is permanent. Chalking is limited only where it reaches the CRAKGON® Membrane.
CRAKGON® repels dust. Erosion is limited to the outer layers since each fiber is encapsulated in paint. Once the fibre surface is exposed, the color is still reflected by the fibers.
The paint-film gets eroded over time by the continuous action of the wind, rain, and dust particles.
Avoided by the specific resin-rich reinforcement fibres found in CRAKGON®.
Over time, small cracks develop throughout the surface of the paint-film.
The paint-film maintains its plasticity through micro sub-superficial capsules within the fibre, which reinforce the paint-film the same way steel-rods do in reinforced concrete, enhancing durability and preventing cracking.
The paint-film loses its elasticity, and begins to peel-off as it breaks away from the substrate.
COMMON PROBLEMS IN NON- REINFORCED PAINT JOB
U.V. rays decompose the paint-film.

We are so impressed with the CRAKGON product we use to reinforce walls we offer our clients a written 10 year guarantee when it is applied by Bob De GrootPaint Services.
Lab tested to last
Laboratory tests prove CRAKGON® prevents the reappearance of surface cracks over 10 years. Longitudinal tests conducted by the National Building Research Institute of the Council for Scientific & Industrial Research (PRETORIA, South Africa) indicate CRACKGON delivers outstanding results over a 10-year timeframe.
Plaster with Crakgon
Plaster exposed for 10 years with CRAKGON® reinforced paint system
Plaster without Crakgon
Plaster exposed for 10 years without a reinforced paint system
Here are a couple of the conclusions made after ten years exposure of paint systems with and without CRAKGON® reinforcing on a plastered wall displaying severe shrinkage cracking:
- In all the systems used, the finishes that incorporated CRAKGON® have proved superior to those that did not
- While the incorporation of CRAKGON® in a coating system results in more paint being required, the effect is that the system remains satisfactory for a longer period.
