FLEXTOOL PRIME EXPOSURE One Coat Sealer-20L onecoat

Surface Preparation

Check the concrete is sufficiently cured, pressure clean the surface (above 2000 psi is preferred) and ensure the surface is free of any grease, oil or any foreign contaminates.

Remove any loosely bound cement and efflorescence by acid etching with hydrochloric acid diluted at approximately 9 parts water to one part acid. Do not allow the acid to dry on the surface during this process, thoroughly rinse the surface with fresh water using a garden hose. You must allow the concrete to thoroughly dry prior to sealing!

Any moisture will affect the sealer, making it look white and cloudy. Moisture will stop surface adhesion and cause delamination.

Application

The surface should look totally even in colour prior to applying Prime Exposure One Coat Sealer, if the surface is not, the cleaning process has to be completed again until the surface is uniform in colour. Any contaminates or efflorescence will be locked under the sealer coating and will remain for the life of the coating.

• Prime Exposure One Coat Sealer cannot be used undiluted on flat trowelled, stippled or unsealed slate impression concrete. Our One Coat Sealer has been designed to be applied neat on unsealed Exposed Aggregate concrete.
• We recommend applying Prime Exposure One Coat Sealer with a good quality roller as this will ensure there is an even coating with no pooling and reduce the amount of lost time in replenishing the roller with sealer.
• After stirring well, apply one even coat with no thinning down for Exposed Aggregate concrete as the surface is porous which allows the sealer to penetrate the concrete surface for suitable adhesion.
• Do not drive on the newly sealed surface for 3-4 days to allow the resin to harden.

Prime Exposure One Coat Sealer can be used the same as Standard Sealer if diluted with Xylene by 20%.

Resealing

For resealing we recommend you follow the above surface preparation process and once the surface is totally dry, apply a coat of Prime Exposure Xylene to reactivate any existing sealer to assist penetration. After the surface has dried follow the application steps.
