Uses / Areas of application
Topciment TopSealer WT One Coat is a two-component polyurethane for protection, sealing, and as a decorative finish, formulated with water-based hydroxylated polyester resins that give it extraordinary performance.
It presents great transparency as well as remarkable resistance to yellowing. The treated substrate material is waterproofed while maintaining its breathability to water vapor.
Like all polyurethanes, it is highly resistant to wear, dirt, and certain chemicals.
As a finishing coat on properly primed metals. Ideal for application on our microcement system, concrete substrates, conventional lime, and cement mortars.
It presents a very natural finish on wood, protecting it from wear and tear and the weather.
For the renovation of parquets and as a transparent protective varnish for walls, floors, and paving in general, such as sports courts or stamped concrete.
As a sealer, it waterproofs the microcement against running water (occasional contact), but it is not a waterproofing agent against standing water (permanent contact).
In the case of soap or detergent residues, rinse immediately, as these can cause marks or grooves to appear.

Preparation of the substrate
Before varnishing, the substrate must be properly prepared. It must be dry, clean, and free of dust, grease, or dirt.
If it has been previously varnished or painted, the previous coating must be removed, especially if it is damaged or deteriorated. This can be done by sanding or stripping, making sure to leave the surface in good condition.
If repair, consolidation, or sealing of joints is required, proceed to prime prior to installation. On mineral or cementitious surfaces, the prior application of Presealer is recommended.
In the case of wood, pre-seal with a wood sealer varnish and sand, according to the manufacturer’s instructions. Then apply two coats of Topciment TopSealer WT One Coat.
In the case of metallic surfaces, clean the surface properly in order to remove rust, grease, dirt, etc. In case of old paints in bad condition, proceed to remove them by basting, stripping, or sanding. Apply a metal primer.
In the case of ferrous metals, use a suitable anti-corrosion primer. Finally, protect it by applying two coats of TopSealer ® WT One Coat.

Application

Prior to sealing with Topciment TopSealer WT One Coat, the use of a primer is recommended.
For microcement apply Topciment Presealer. It will be necessary to allow 4 hours after applying Presealer two coats before proceeding to seal with Topciment TopSealer WT One Coat and allow 24 hours between coats of Topciment TopSealer WT One Coat to dry.
Not to be applied at temperatures below 15°C and not above 30°C. It can be applied by spray, brush, or roller, covering the surface well. For best results, it is recommended to apply two coats of the product. The second coat is applied after 24 hours (low temperatures and ambient humidity delay drying). The first coat is sanded with 400 grit sandpaper and the last coat does not require sanding. Check the adhesion in a corner or hidden area before proceeding with the total coating. Allow the polyurethane to cure for at least one week. Polyurethanes reach their full chemical properties after 7-14 days, depending on the environmental conditions (humidity and temperature)

Maintenance

• Allow the polyurethane to dry for at least one week before wetting.

• Polyurethanes reach their full chemical properties after two weeks.

• Do not use detergents or cover before two weeks.

• Clean with a damp cloth and our Ecoclean detergent or neutral soap to prolong the life of the sealant. Do not use aggressive cleaning products such as bleach, acetone, or hydrochloric acid.
