Surface Preparation

Clean and dust the walls down at each step. Poor adhesion of underlayers could cause the crackle to lift itself and the previous layers of paint down to the weakest point, ex. sheetrock mud dust beneath the primer.

To fix such areas, sand, reprime and paint as necessary and reapply the crackle to the affected areas.


Extensive Crackle Testing

Extensive Crackle testing conducted at Golden

General rules:

  • When applying Rough Cracking and Smooth Cracking Textures:

If you go thick, you don’t need size. If you use size, don’t apply thick. What is "thick"?

  • We've tested different base paints, they work differently. Further, paint companies will change their formula over time and so to be sure, everything needs to be tested.
  • To create the best adhesion and the most interesting crackle pattern: use Proceed Low Absorbency base paint as primer and paint beneath our Crackle System. (include this on label info)



The combination of primer and base paint and sheen of the base paint will influence the ultimate crackle effect achieved.

Further, the history of the wall will also influence the crackle effect.

It is extremely important to note that these crackles are strong materials and may cause delamination of a primer coat to the original sheet rock. Please be prepared that in spots, the Smooth Cracking Texture has been known to lift.

Golden can not predict when and where lifting may occur however here is our best recommendation on how to handle the occurence of lifting and your client:

Explain primer/base combo, history of walls and how we can’t predict completely what will happen. There may be weak points in the underlayers of paint.

Summary:

To create the best adhesion and the most interesting crackle pattern: use Proceed Low Absorbency base paint as primer and paint beneath our Crackle System.

Internal Link to how to have Low Abs Tinted at a paint store:

Create a spreadsheet/chart - Next best recommendation using commercially available base paints: Basepaint/Primer analysis: Without size, no adhesion failures over any combo except SCT at 175 ml, slumps.

BM primer – most absorbent of SW, Proceed and Kilz

Any, but do not use Semigloss of any of these with size.. Benjamin Moore: Do not use eggshell

Sherwin-Williams:

Valspar:

Without Crackle Size all primers, basepaints, and sheens have excellent adhesion but always test.

Maximum Thickness

Notes on Maximum Thicknesses and the use of Crackle Size:

  • With both Smooth and Rough Cracking Texture: 175 ml is max thickness, do not use Cracking Size beneath this thickness or apply over semi gloss, causes slumping and lifting.
  • Cracking Size magnifies the differences between the thicknesses and sheens.
  • Crackle Size creates hold out of pattern, large platelets and no smaller cracks visible.

(Note to Proceed team, I'd like to include this info but not sure how: BM SG and Satin, SW and VAL Satin all have something in them to create hold out and lose adhesion of RCT and SCT.)

Further detailed information: Rough Cracking Texture:

• 175 ml: No size over Pro/SW primers on all bases

Maximum thickness without Crackle Size

• 75 ml: 1 coat of Size over V SG and Pro/SW primers. Do not use 1 coat of size over BM sg and V s

• 25 ml: all fine except without size photo ideas: 2 coats of size 75 ml = the crackle pattern of 175 ml w/out size….photo and do cost analysis..have side by side images

Smooth Cracking Texture:

• 175 ml: not recommended

• 75 ml: no size, Kilz/Sw primer and semigloss or satin?

• 25 ml: pro 2 coats and sw largest cracks

Transparent Cracking Glaze

• over Proceed

An article idea: When Size meets Texture Generally speak about who we tested.
