TopSealer® WT Dragon: the most desired water-based polyurethane varnish

At Topciment® we have a wide variety of varnishes for microcement, the TopSealer® family. In it we find all types of polyurethane sealers, water-based, acrylic and solvent-based, with different performances and functions, so that the professional applicator can choose the one that best suits their demands.

In our eagerness to surpass ourselves to meet the demand and offer the best possible products to the market, TopSealer WT® Dragon joins our family of water-based polyurethane varnishes.A sealer that if you dare to try it, you won't want to hear about solvent-based varnishes again.

A water-based polyurethane varnish with unbeatable performance

TopSealer WT® Dragon is a polyurethane sealer specially designed to protect microcement coatings. Despite its high performance, being formulated with hydroxylated polyester resins and isocyanates in water base, it supports more.

This water-based polyurethane varnish of a two-component nature stands out, above all, for guaranteeing superior chemical resistances. Therefore, as we will see later, it is our best water-based varnish for wet areas such as bathrooms (except for swimming pools, for which we have developed TopSealer WT® Pool).

1. Waterproof to running water

Microcement in bathrooms is in good hands with TopSealer WT® Dragon, as it waterproofs the coating against occasional contact with running water. Likewise, with this two-component water-based polyurethane varnish, the maintenance of water vapour breathability is guaranteed. If you don't want worries in wet areas, this is the sealer you are looking for.

2. Excellent resistance to chemical agents

From notable resistances to water to extraordinary resistances in terms of chemical agents and other liquids. This water-based polyurethane sealer has a magnificent resistance to bleach, lye, oil, vinegar or wine, among many others.

3. High resistance to wear by abrasion

With a König Hardness of 200 seconds at 14 days of curing, TopSealer WT® Dragon has very good resistance to abrasion, traffic, and scratches.

4. Does not yellow outdoors

In the same way that we pride ourselves on the versatility of our microcement systems, which can be applied outdoors, our sealers are not left behind. In this regard, TopSealer WT® Dragon does not yellow under the action of sunlight, thus making it an excellent option as an outdoor sealer.

Where to use the water-based polyurethane varnish TopSealer® WT Dragon

In general terms, TopSealer WT® Dragon presents a high compatibility with a variety of supports. As we have specified before, it is not only considered as a microcement varnish even though it is its main function.

This two-component water-based polyurethane varnish, which is available in gloss, satin and matte, can be applied on all those surfaces where both a good aesthetic and protective finish is desired. In the case of wood, for example, it offers a very natural finish.

Returning to our microcement systems, which is what concerns us in these lines, TopSealer WT® Dragon is ideal for protecting all our microcement systems without exception: cement base, lime base and epoxy base.

• Impeccable in damp areas such as bathrooms

If you want to play it safe in spaces exposed to water and environmental humidity, such as bathrooms, TopSealer WT® Dragon is a guarantee of success. Its greater chemical resistances compared to other water-based varnishes give it the lead in this field of use. You won't regret it.

• Convenient for outdoors

Most of our varnishes are suitable for coating floors and facades exposed to solar action. However, the water-based polyurethane varnish TopSealer WT® Dragon provides an extra resistance and that is why we recommend it as the perfect sealer for the weather.

• Safe in high wear areas

Warehouses, offices, restaurants... all are areas that suffer from high wear and tear. Surfaces that require harder microcements, such as Industtrial (epoxy base), Natture (lime base) or Sttandard (cement base), and also more resistant sealers. TopSealer WT® Dragon is more than valid to seal and protect these areas.

How to apply the water-based polyurethane varnish TopSealer® WT Dragon

TopSealer WT® Dragon is a two-component water-based polyurethane sealer that is easy to apply. It is designed to be applied in just two coats and in less time than other varnishes. You can do it with a gun, brush or roller. Broadly speaking, these are the steps to follow to seal the coating.

1. Shake the component A of the varnish

It is important to homogenize the product before using it as a sealant. Shake component A and then let it rest for a minimum of 30 minutes.

2. Mix component A with component B

When component A has already rested, add component B of the TopSealer® WT Dragon water-based polyurethane varnish by stirring at low revolution. The proportion of the mix is as follows: 3 parts in kg of A for 1 part of B. Important: at an ambient temperature of 20ºC, the lifespan of this mix is 1 hour.

3. Prepare the support before applying the varnish

Check that there are no traces of dirt, grease or dust on the surface. If so, clean. In the event that the support is deteriorated or presents damage, repair before applying our two-component water-based polyurethane sealer.

4. Apply two coats of Presealer

On mineral, cementitious or microcement surfaces apply two coats of Presealer (leaving a drying time of 4h between them). Allow a period of 12h to elapse.

5. Seal with two coats of TopSealer ® WT Dragon

Once the mandatory 12 hours of drying have been completed, definitively seal with our TopSealer® WT Dragon. The drying hours between layers will range from a minimum of 12h to a maximum of 24h. Only the first layer will need to be sanded with a 400 grit sandpaper.
