Applying Polyshield and AquaMax Pro for Floors

Applying Polyshield

Follow the directions below to apply Polyshield.  Polyshield is a 3-Part product. That puts a very strong, durable impenetrable coat onto microcement surfaces.

The installation guide includes a video demonstration of how to apply the sealer efficiently and effectively, plus detailed written instructions.

See Technical Info for the key technical facts.

Mixing the Polyshield

Combine  Polyshield and Polyshield Comp B in a mixing jug and stir gently with a mechanical paint mixer on a low speed for 3 full minutes.  Use a timer to ensure an accurate mixing time. Failure mix for 3 full minutes will result in reduced working time & incorrect consistency.

The mix will appear thick at first but will loosen as you mix. To increase working time and fluidity, add 125ml Polyshield Thinners per 1l of Part A.

You will need 2l Polyshield + 800ml Polyshield Comp B + 250ml Polyshield Thinners per 10m2.

The mixing ratio is 4 x Polyshield : 1.6 Polyshield Hardener: 500ml Polyshield Thinners.

To get the full benefit from the sealer, you must use the full consumption across the area.

Applying the Polyshield

Using a Squeegee Trowel on a Pole will help you to apply the Polyshield quickly and effectively.

Pour the Polyshield from the starting point across the width of the room. Using light pressure on the trowel, spread the Polyshield evenly across the floor, working from one side of the room to the other, taking care to get even, full coverage across the surface.

Aim for even coverage without ridges or thick spots.

IMPORTANT: Eye Protection, Gloves, Filtering Masks, suitable for use with Polyaspartic products must be worn when working with Polyshield.

Leave to Dry

Polyshield should be dry in around 12 hours but may vary depending on temperature and humidity. The finish is very glossy, so you’ll need to add a coat of AquaMax Pro for Floors over it to achieve the desired finish.

Mixing AquaMax Pro Floors

Mix the AquaMax Pro Comp A with the AquaMax Pro Floors Comp B in a mixing jug and stir gently with a paint stirrer for at least a minute. Do not whisk as it will put too much air in the mix. Leave to rest for a couple of minutes before applying.

For 1 coat, you will need 500ml AquaMax Pro Comp A + 100ml AquaMax Pro Floors Comp B per 10m2.

The mixing ratio is 5 x AquaMax Pro Comp A : 1 x AquaMax Pro Floors Comp B.

The mixture will only last for 45 minutes once combined.

Applying the AquaMax Pro Floors

Use a medium pile roller to apply the AquaMax Pro evenly across the entire area.

Starting in one corner, apply the AquaMax Pro in an area and then go back over it very gently with the roller to remove any excess product, air bubbles and lines.

Work quickly & randomly keeping the edge wet.

Silicone Open Edges

Once the sealer is dry, take off the tape around shower wastes and open edges, and run a bead of silicone along the join to prevent any water getting behind the microcement.

IMPORTANT: Like all cementitious products, microcement takes 28 days to full harden. It’s at it’s softest for the first 14 days after laying. During this time it should only be subjected to light use and light foot traffic.

Ensure you cover the full area with AquaMax Pro and use the full amount provided (500ml+100ml per 10m2 for each coat).

Leave to Dry

Leave for at least 48 hours. Light use only for the first 14 days.

Any heavy work is not recommended, but if it does take place then we recommend that you cover the floor with a breathable material or only cover down whilst working & lift the protection off for the majority of the time. The surface needs to dry out and harden. If airflow is restricted, it will stain & not cure correctly.
