There are a number of important rules of thumb to follow when deciding how much catalyst to add: Never use less than 1% even in the summer, just mix less resin at a time.

Never use more than 4%, the gel time will not reduce any further beyond 4%.

Never underestimate the effect of temperature. Resins will not cure at or below freezing and will always cure much quicker in direct sunlight.

When topcoating late in the day, add more catalyst to allow for the lack of sunlight.

In Winter use fast catalyst, in Summer use standard catalyst, in very hot conditions use LPT (Long Process Time) catalyst.

Remember: Any catalysed resin left in the bucket will exotherm. Heat is generated as the resin cures, so it should be kept well away from other stored materials. Water can be poured over the resin to suppress the heat gain.

Always mix the catalyst into the resin thoroughly before using the resin (i.e. a good couple of minutes for a 10 litre bucket.) Failure to do this can result in 'streaking' on the laminate, where streaks of uncured resin will remain visible and ultimately lead to a failure in the laminate.

Fast cures can result in an inadequate bond.

 

When estimating the amount of materials needed for a roof, there are a number of factors that should be taken into consideration. Firstly, calculate the total area of the roof in square metres and always allow an extra 10% for the main materials to account for wastage or unforseen problems. The values given below are only an estimate and will depend on the detail of the roof surface. The quantities for decking board are based on an exact calculation of the area of coverage of each board, in practice, this should be considered a conservative estimate.

Notes
Before starting any roof always calulate the area of the roof and take into account the complexity of the job before choosing your materials.

Always ensure that you plan ahead to have enough materials to complete the job. Always allow extra time and materials for any detail.

Many of the ancillaries are dependant on the number of people working on the roof; increase them accordingly.
