Synteko Classic Problem Solver
Problem	Reason / Correct Procedure	How to Repair /Correct
Gloss level is incorrect	Matting agent settles at bottom of bottle when standing.	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 10 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.
Primer 1660 dries too fast when applied by brush	Always add 10% retarder when using a brush.	Sand to bare wood and seal again.
Discoloration of exotic woods when sealed with Synteko Classic	Seal with Primer 1660.	Sand to bare wood and use Primer 1660 for priming.
Discoloration of smoked oak, brown beech or or chemically treated woods
Film forms too fast, wrinkles in suface	Avoid draught over surface in order to allow finish to dry evenly	Let coat harden, then screenback and finish again.
	Prior coat must be dry and sandable before next coat is applied.
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	When Synteko Classic is 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 Primer 1660 or 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.	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
