Frequently asked questions about Topsealer
What are Topsealer varnishes used for?
They are sealers that protect microcement, decorative concrete and other continuous coatings against wear, scratching, water and chemicals, enhancing their colour. Depending on the system, they are also suitable for wood, parquet or stone.
Which Topsealer system suits me?
All in One is one-component and the easiest to apply, designed for furniture, countertops or washbasins. The WT range (One Coat, Dragon, Natural Effect, Spray) are water-based two-component products; DSV and PRO+ SLOW are solvent-based. PRO+ FAST cures quickly in a single coat, and WT Pool is designed for submerged surfaces.
How are component A and component B mixed?
Each component A is mixed with the component B of its own system and in the indicated ratio, which varies by system (for example, 5:1 for WT One Coat or 2:1 for DSV). Stir at low speed until the mix is homogeneous and apply it within its pot life. All in One needs no mixing.
Can I use it outdoors or in swimming pools?
Yes: WT One Coat, WT Dragon, DSV, WT Spray and All in One matt are suitable for indoors and outdoors. All in One satin is recommended for dry interiors or decorative items. For swimming pools, fountains or ponds, use Topsealer WT Pool, designed for continuous immersion in water.
What finishes can I achieve?
There are matt, satin, gloss and super-matt versions, as well as the Natural Effect finish, with a subtle satin sheen. They are transparent, enhance the colour of the coating and do not yellow over time.
When can I use the surface after sealing it?
In most systems full curing is reached after 7 days; in the meantime, avoid water and harsh products. With WT Pool, do not fill the pool until 7 days after the last coat.
