How to Repair /Correct
|
Gloss level is incorrect | Matting agent settles at bottom of bottle when standing. Inadequate mixing of matting agent. |
Screenback surface and refinish again with correct gloss level (35,50 or 90). Last coat always gives gloss level. |
Always shake bottle thoroughly before use in order to disperse matting agent evenly. Leave bottle to stand for 5 minutes allowing air bubbles to surface. |
Always allow for adequate ventilation (refer to ventilation document). |
|
Larger container requires more vigorous mixing. Alternatively use mixing/application tray to adequately mix product. |
||
Finish dries too slowly | Insufficient ventilation | Heat room and provide air movement after film formation and when surface is tack-free. |
Do not leave finish in a cold car overnight; if this happens, warm to room temperature in max. 40oC hot water. |
Always allow for adequate ventilation (refer to ventilation document). |
|
Finish must be at room temperature, which should be over 15oC. |
||
Relative humidity of air should be below 85% and moisture in wood below 15%. |
||
In cool, humid conditions you may increase amount of hardener to 12% (instead of 10%). Apply 3 thin coats instead of 2 heavy coats. |
||
Finish remains soft | Either no hardener or too little hardener used. |
Spray floor with or rub in a mixture of 20% hardener/80% methylated spirit. After curing, re-screen surface and finish again with adequate ventilation. |
In cool, humid conditions you may increase amount of hardener to 12% (instead of 10%). Apply 3 thin coats instead of 2 heavy coats. |
||
Finish dries too fast in dry weather. Overlapping marks appear. |
Add 5-10% Retarder 1670 in last coat. | Re-screen and finish again. |
Film forms too fast, wrinkles in suface | Avoid draught over surface in order to allow finish to dry evenly |
Let coat harden, allow for solvents to evaporate, then screenback and finish again. |
Prior coat must be dry and sandable before next coat is applied. Solvents are still evaporating |
||
Pimples/impurities | Vacuum building site carefully: floor, walls, tools etc. Close windows until finish is tack-free |
Re-screen and finish again. |
Remove last dust from floor with a cloth moistened with methylated spirit before finishing (“Tacking” is essential.) |
||
Continuous smell of formaldehyde | As soon as Synteko Classic is touch dry, open windows. | Insufficient ventilation (refer to ventilation document). |
Provide adequate ventilation every 10 minutes during winter |
||
Bad abrasion and scratch resistance | Do not place furniture on floor for at least 2 days. Always fit felt floor protectors under all furniture. |
Remove minor scratches with Synteko Newshine. |
Finished surface must be treated carefully for the first 60-90 days as the coating has not cured through. The result is white scratch lines. |
Re-screen and finish again. | |
Always keep floor clean. Vacuum regularly or use a dust control mop daily to keep grit away from finished surface. |
See maintenance instructions. | |
Clean regularly with Synteko Super Clean after 1 month |
||
Discoloration because of sunlight (ambering) | Normally, finishes do not contain a UV-filter. However, wood itself ambers because of sun influence. Always try to keep direct sunlight off timber floors. |
Differences in colour disappear when sanded and sealed again. |
When carpets are rearranged obvious colour differences eventually disappear. |
||
Synteko Classic does not adhere to previously finished floors or hardwood floors |
Do not recoat polyurethane finishes or waterbased finishes with Synteko Classic. |
Completely remove old finish. Then coat with Synteko Classic. |
Pre-finished floors and laminate floors cannot be recoated with Classic. |
||
It is recommended to test a sample area before proceeding with work. |
||
Wax must be completely removed by sanding. | ||
Wood floor surface marks easily from food stains or water puddles |
Insufficient coats applied. | If needed localise and spot repair stain/mark by sanding and coating to damaged area, followed by recoating area to blend patch repair. |
Finish coats applied are too thin. | ||
Surface coating has cracked due to it being to brittle. This is generally caused by too much hardener added when finish mixed prior to application. |
||
Finish surface scratches easily after coating cured | Floor surface not swept regularly and /or ineffective external door mats |
Use electrostatic mop daily to minmise grit. |
Incorrect felt floor protectors fitted to furniture | Replace felt floor protectors. | |
No walk off mats at high traffic areas | Replace external door mats as well as install walk off mats internally at high traffic points. |
|
Floor finish too brittle due to too much hardener added at time of mixing and application, or coats are too thin. |
If necessary re-screen and recoat. | |
Synteko Classic finish has cracks | Do not add too much hardener (Max 12%). | Sand down to bare wood and coat again. |
Do not apply more than 3 coats |
