COLOR DIFFERENCES OR SHADING
The look of uniform color with variations in shade or appearance.
||SOLUTION TO PROBLEM
|VARIATIONS BATCH TO BATCH - Each batch of material will differ from other batches of the same material.
||Roughen the surface and apply a topcoat from one continuous batch production run.
||Check batch numbers prior to using and if necessary box the batches to form one continuous batch.
|EXPOSURE TO SUNLIGHT - Exposure to sunlight can cause some areas of a floor to discolor or fade.
||Roughen the coating and apply an aliphatic colored topcoat that is uv stable.
||Plan ahead. Use materials that are suited to your particular exposure conditions.
|PRODUCT SETTLING - If a product settles, the applicator must scrape out all of the material or color shading can occur.
||Roughen the surface and apply a properly mixed topcoat to the substrate.
||Make certain that the product expiration date has not been exceeded and use mechanical stirrers or shaking equipment if necessary.
|SPOTTING / DISCOLORATION - Chemical attack can cause spotting in isolated areas or affect the entire floor.
||If surface integrity is maintained, then roughen and recoat with a more chemically resistant topcoat.
||Before installing a coating system, check the diversity of chemicals that will be exposed to the floor.
