In Good Condition: Wash down with Yacht Line Super Cleaner, rinse with fresh water and allow to dry. Abrade with 280-320 grade (grit) paper.
In Poor Condition: Remove all previous coatings and prime the substrate.
PRIMING: Substrate preparation is covered separately on the primer datasheet.
BARE WOOD: Prime with Yacht Primer or UCP.
STEEL: Prime with Yacht Primer or Interprotect.
ALUMINIUM: Prime with Etch Primer followed by either Yacht Primer or Interprotect.
GRP: Wash down with Yacht Line Super Cleaner, rinse with fresh water and allow to dry. Abrade with 180-220 grade paper.
AGED/WEATHERED GELCOATS: Due to the potentially porous nature of aged/weathered gelcoats the risk of solvent/moisture entrapment after painting is much higher than when gelcoat is new. As a result this entrapment could lead to blistering of the paint film. To reduce the risk of paint film blistering it is recommended that 3 coats of Interprotect are applied to seal the gelcoat. Interprotect must be overcoated with Polyurethane Basecoat prior to topcoat application.
ALL SUBSTRATES: Use Pre-Kote undercoat. If spray applying Toplac, Pre-Kote must be aged a minimum of 14 days. If this is not possible Polyurethane Basecoat can also be used as an undercoat.


Method Sand the undercoat smooth with 320-400 grade (grit) wet or dry paper. Remove dust with a dust wipe. Apply 1-2 coats.


Hints Mixing Stir well before use.
Thinner YTA800,YTA063 Thinner No.1 (Thinner No.10 for spraying)
Thinning In warm or windy conditions up to 10% of thinners may be added to ease application.
Cleaner YTA800 Thinners No.1
Ventilation and Humidity Control Apply in dry, well ventilated conditions. Avoid applying late in the evening as condensation can cause a loss of gloss overnight.
Conventional Spray Thin 10-25% with Thinners No. 10 to a viscosity of 18-22 secs (BS4) or 16-20 secs (DIN4). Pressure: 3-4 bar. Tip Size: 1.1-1.4 mm. NOTE: Pre-Kote undercoat MUST be aged a minimum of 14 days before application of Toplac.
Other For lighter colours, mix the first coat of finish 50:50 with the undercoat to improve the depth of colour and opacity. For best results when applying by roller, smooth off with a pad or brush.

Exposure to air and extremes of temperature should be avoided. For the full shelf life of Toplac to be realised ensure that between use the container is firmly closed and the temperature is between 5C/40F and 35C/95F. Keep out of direct sunlight.
Toplac should be kept in securely closed containers during transport and storage.

Safety GENERAL: Read the label safety section for Health and Safety Information, also available from our Technical Help Line.
