MACt Seal (4L)
MACt Seal (4L) is a two-component urethane acrylic hybrid twin system crosslinking resin system with an additional final coat option – “MACT guard” with this sealer which bonds a silicon repellent layer to your sealed product. The final cured film is colourless and non-yellowing. Developed to have a very high scratch resistance, the coating, once cured, is resistant to a wide range of contaminants.
Mixing MACt Seal (4L).
- The base to activator ratio is 16:1 by volume.
- Weight or measure out the correct activator amount for the base amount desired. Add the activator and stir until fully dispersed, approximately 3 mins. From the moment of adding the activator, you have approximately 2 hours of worktime to use up all the product mixed.
- Apply multiple coats allowing time between each coat to for the film to dry. High humidity conditions will slow down the drying process.
- There is no need to back roller off the applied coat, but back rolling can be undertaken if desired.
- Multiple heavy coats will produce a high gloss finish and take longer for the cure mechanism to finally crosslink the system.
- A few thin coats will cure faster but produce a matt finish.
- If the MACT Guard option is to be applied, mix the MACT Guard with the normal activator at the same ratio but only mix sufficient to coat the job ONCE
- MACT Guard can be only applied as a final layer, attempting to apply any sealer to this final coating will result in rejection of the application and the Job will need to be mechanically sanded back to the cement before reapplying the sealer system.
Application of MACt Seal (4L)
- The special non foaming formulation is designed to be laid down with the minimum of fuss using a foam roller. This system is user friendly and quite user tolerant.
- MACT Guard can be only applied as a single, final layer.
- Do not apply sealer that has been mixed for over two hours.
Curing of MACt Seal (4L)
Allow 24 hours for the first crosslink reaction to take place and 7 days for final hardness to be achieved.
