No, Quantum products are designed to penetrate the timber and they cannot do this over an acrylic surface coating. If you want to recoat a surface previously coated with an acrylic, you will have to sand off the previous coating.

A transparent stain adds colour to a timber surface, whilst still showing the timber grain definition. Adding a transparent stain to a clear coating will extend its lifespan, however recoat time will depend upon penetration, application and most importantly exposure to UV rays. As a guide recoat time is between 3 to 5 years.

Opaque stains result in a solid colour but still allow the timber profile to show through unlike an acrylic that sits on the surface. Opaque stains have a longer life span, typically 5 to 7 years. Horizontal surfaces such as decking may need to be recoated more frequently, a simple wash down and re-apply is

All Quantum penetrating oils will oxidise at the end of their life span and just disappear, acrylics on the other hand will crack and peel and have to be removed before recoating.

TIMBRE PLUS Vertical has a Teflon wax in it that helps to aid beading and repel water. TIMBRE PLUS Decking on the other hand has a non-slip wax, like surfboard wax, that helps to prevent slipping.

Linseed putty or exterior grade fillers.

The ideal time to coat external timber is when the temperature is rising, so early morning is the best time to start.

Work along the length of the board, if the coating dries too quickly, finely mist the timber with water to slow the drying time.
