Applying Manns Trade Extra Tough Pro Floor Varnish
Always do a test area before starting any project to assess product suitability and final finish. Follow the manufacturer's instructions on the container at all times. Stir the varnish thoroughly before and periodically during use.
Catalyst Mixing Guidelines
Manns Trade Extra Tough Pro Floor Varnish is very versatile and easy to use. It comes supplied with enough hardener / catalyst for the varnish. Although the catalyst is required to achieve the strongest and most durable finish, it adds around 5% strength to the final finish.
Mix 10 parts lacquer to 1 part catalyst by volume and mix well prior to use. The catalysed lacquer should be used within 5 hours of mixing.
An alternative method of measuring the amount of catalyst to floor varnish is to measure the height of the liquid in the bottle of hardener and varnish, and to mark the containers with a permanent marker pen in increments of perhaps a quarter. By doing this, it's easy to pour 1 quarter, half or three quarters of the varnish as required with the correct amount of hardener. The amount of hardener added to the varnish does not have to be precise down to the exact millilitre. If a little too much or too little is added, it will not have a negative effect on the final finish.
If not using a dedicated primer, 3 coats of Manns Extra Tough Pro Floor Varnish is recommended. The first coat can be applied as a base coat without the hardener. The hardener can then be added for the second and third coats.
Optimum application of this varnish is achieved between 18°C and 22°C with good air movement and ventilation. Floors varnished with Manns Trade Extra Tough Pro Floor Varnish should not be subjected to environments with temperatures of less than 2°C.
- For best results, apply Manns Extra Tough Pro Floor Varnish using a microfibre roller or paint pad
- Apply evenly, making smooth passes with the roller or pad, predominantly along the grain taking care to avoid 'pooling'
- The approximate single coat coverage of the lacquer is 8m² per litre. This however is dependent on the method of application, porosity of the timber and the desired finish
- Leave adequate time between coats, de-nibbing between coats to aid adhesion
Some Points of Note:
- Do not apply more than 3 coats of polyurethane floor varnish in one day
- Do not overcoat with solvent-based products
- Avoid contact with iron, copper, zinc, aluminum and platinum as these can attack the aqueous polymer
- When coating darker timbers, such as Walnut, Mahogany or Teak, slight bleaching may occur
- Water-based products should have nominated finishing equipment
- Excessive coating weights can lead to cracking or lifting
- Do not subject floors to heavy foot traffic, place furniture or move furniture across the floor surface for at least 72 hours after application
- Do not place mats or rugs on the newly varnished floor surface for at least 5 days after application, as this will impede final cure
- The use of good quality entrance mats and furniture pads after this time is recommended to avoid damage to the finish
Brushes and equipment should be cleaned immediately after use with warm, soapy water and wiped dry with a dry cloth.
