Sealing with solvent-based acrylic, resin sealers

 

 

There are several key elements required to seal concrete using solvent-based sealers. The best practice provides for a trouble-free application, job satisfaction and a contented customer. Understanding some of the basic requirements will help you achieve a successful outcome. Before you start your next job, think about the below essential factors.

Understand the properties of the concrete.

It is helpful to identify:
What is the Mpa?
How was it finished?
How old is it?
Were curing compounds used?
Is it new or old concrete?
This information will determine what sealer you choose and what preparation to do.

Environmental and weather considerations.

Temperature, wind speed and time of day all impact on applying the sealer. Sealing should only be undertaken between 10ºC and 32ºC and wind speed should be less than 12 knots.

Preparation of the concrete substrate.

Depending on the properties of the concrete, the preparation is essential. Preparation for old and new concrete is very different.

Choose a suitable product.

Use a good quality, high performing sealer from a reputable company.
Cheap sealers are full of solvent and not much resin, so they will not last.

Read and understand the product Technical Data Sheet (TDS).

It is imperative that everything about the sealer and its application
is understood before attempting to use and apply it. This information is in each TDS.

Choose suitable application equipment.

The equipment used depends on the job. You should consider:
Size of job
Type of concrete
Weather conditions

Use the correct application method.

Whether spraying, rolling or brooming the sealer, there is one golden rule…thin coats are best.

Ensure proper product drying times.

Use the TDS to ensure you allow the correct amount of time for the sealer to dry between coats. Make sure there has been enough time to dry between pedestrian and vehicular traffic.

Clean and maintain the sealed concrete.

It is imperative that sealed concrete is clean and maintained. Provide a guide to the customer so they understand how to look after the surface.
Inform the customer on the timeline for resealing of the concrete. This is approximately 18 months, depending on traffic.

If the key requirements are not followed, it is very likely the application of sealer will fail. The job will then need to be redone.
Redoing a job is much more time consuming and expensive than doing the job correctly the first time.
