AVOIDING 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. |
