General information:

  • Each Crackle product has a minimum thickness required in order to make the cracks visible. If after applying untinted crackle products and no cracks are visible, most likely there is not enough material on the surface in order to allow it to crack.
  • When applying Rough Cracking and Smooth Cracking Textures:
         *If you apply them thick, you don’t need size.
          The textures will produce large cracks on their own.
         *If you use size, don’t apply them thick.  
          Slumping may occur if thick applications of the Cracking Textures
          are applied over the Crackle Size.

Minimum Thickness

Here is a gallery of images of Minimum Thickness with and without size for each of the Crackle Products:

Transparent Cracking Glaze: a thin brushstroke or 240 sq. ft/gallon or 6 mil (a sheet of copy paper is about 4 mil thick)

Smooth Cracking Texture and Rough Cracking Texture: 144 sq. ft/gallon or 10 mil thicknesses (premium glossy photo paper is 10 mil)

Troweled on thin enough to see through the Texture. On left: no Crackle Size below Smooth Cracking Texture; on right: one rolled coat of Crackle Size below application
Troweled on thin enough to see through the Texture. On left: no Crackle Size below Rough Cracking Texture and no cracks are visible; on right: one rolled coat of Crackle Size below application however, this application is too thin to produce cracks

Maximum Thickness

Notes on Maximum Thicknesses and the use of Crackle Size (include a red/green chart):

  • Cracking Size magnifies the differences between the thicknesses and sheens of the basepaints used beneath the Crackle products.
  • Cracking Size over higher gloss sheens will create a hold out of pattern meaning larger platelets with not as many smaller cracks visible.
  • Review Crackle Surface Preparation and Protection for further recommendations on choice of base paint, sheen for surface preparation.


Here is a gallery of images of Maximum Thickness with and without size for each of the Crackle Products:

Rough Cracking Texture The maximum thickness recommended is 175 mil or 8 sq. ft/gallon (about the thickness of 3 pennies), apply this thickness only over Flat or Eggshell sheens and do not use Cracking Size underneath this thickness.

175 mil thickness On left: no Crackle Size below Rough Cracking Texture; on right: one rolled coat of Crackle Size below application
250 mil thickness (1/4") of Rough Cracking Texture without (left) and with(right) Cracking Size


An interesting Note:

Use two coats of size and an application of 75 mil(about the thickness of a nickel) of Rough Cracking Texture to create a similar effect of one coat of Rough Cracking Texture at 175 ml(about the thickness of 3 pennies):

Maximum thickness of Rough Cracking Texture at 175 ml without Cracking Size
75 ml thickness of Rough Cracking Texture with two coats of Cracking Size

The difference in the material cost of these two applications is:


Maximum thickness of Rough Cracking Texture at 175 ml(about the thickness of 3 pennies) without Cracking Size =


75 ml(about the thickness of a nickel) thickness of Rough Cracking Texture with two coats of Cracking Size =



Smooth Cracking Texture

The maximum thickness recommended is 150 ml (an 1/8" = 125 ml), apply this thickness only over Flat or Eggshell sheens.

Maximum thickness of Smooth Cracking Texture without Cracking Size














Transparent Cracking Glaze

The maximum thickness is created by applying it with a brush, at the maximum thickness (about the thickness of ), the Transparent Cracking Glaze will sag.

29 sq. ft/gallon or 50 mil
