SOLUTION TO PROBLEM |
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. |
