HOW TO GUIDES

PROBLEMS & RECTIFICATION PROCEDURES

Ecowoodoil is made from highly penetrative Plant Oils, and when applied correctly will deliver a “matt finish”. Over application of Ecowoodoil resulting in “shine” will result in an unsatisfactory finish which will attract dirt and scratch & mark easily. Failure to brush or cloth in the final coat or after recoating (as instructed on the can) will also result in an unsatisfactory finish.

OIL IS STILL TACKY AFTER 24 HOURS

Possible Causes are:

• Poor preparation of timber surface Oil is unable to penetrate the timber’s surface
• Over application of Oil – either more than 2 coats or 2nd coat not sparingly applied.
• Failure to allow sufficient drying time between 1st and 2nd coats
• Failure to brush or cloth in the final coat or after recoating

TIMBER SCRATCHES OR MARKS EASILY

This is where the surface of the timber marks easily once the oil has dried. The finish may be peeling or lifting. Possible Causes are:

• Poor preparation of timber surface Oil is unable to penetrate the timber’s surface
• Over application of Oil – either more than 2 coats or 2nd coat not sparingly applied.
• Failure to allow sufficient drying time between 1st and 2nd coats
• Failure to brush or cloth in the final coat or after recoating

WHITE MARKS OR “MILKY” LOOK

This is where the Timber surface shows up white, or has “crazing” or “crocodile skin” type markings. Possible causes are:

• Timber has become exposed to moisture prior to drying – Oil applied with insufficient drying time prior to evening dew/moisture or rain.
• Insufficient drying time allowed after “wash-down (2 to 3 days)”. The moisture is still leaving the timber, causing emulsification.

DULL OR PATCHY AREAS

Possible causes are:

• Poor preparation of timber surface
• Insufficient drying time allowed after “wash-down (2 to 3 days)”. The moisture is still leaving the timber, causing emulsification.

RECTIFICATION PROCEDURE

Within 48 hours of application, apply a coat of Ecowoodoil, leave for 15 to 30 minutes. Then rub the problem areas firmly with a “Scotchbrite” type scouring pad. (For large areas a Polivac or Canterbury polishing machine fitted with a scouring pad can be used). Then rub the surface with a lint-free cloth so that there is no wet oil left on the timber’s surface. If longer than 48 hours after the application of Ecowoodoil, using a steam cleaner or sanding may be necessary.

NOTE FOR NEW TIMBERS: If the surface deteriorates rapidly and has a “dry” look, then the preparation procedures for NEW timbers have not been followed, particularly with high moisture/tannin content timbers where Woodguard is required. This can be rectified by applying the ‘wash-down” procedure and reapplying one coat only of the advised Ecowoodoil product. See Preparation of New Timbers Guide for the "wash down" procedure"
