The main reasons to seal a table top

Sealing a tabletop is important for both comfort of use and preservation. Haptic properties at touch, lasting optical integrity and protection against heat and moisture determine the quality. The cleaning ability is also influenced by the seal.

Open and porous surfaces

As one of the most widely used household utensils, the need for good sealing on tabletops is particularly important. Too blunt or too smooth surfaces can be just as disturbing as staining. The protection against liquids should work.

If the tabletop surfaces are made of porous materials, the sealing is required for maintenance and must be done relatively often. Typical types of sealing for open unpainted wood, natural stone and concrete is the application and polishing of special care oils.

By oiling the table top, the pores are closed and the surface is covered with a protective film. This layer lets beads roll off and delays the suction effect, so that in case of prompt reaction by cleaning stains can usually be prevented.

Remove porosity

When a table top is painted, a final transparent finish must protect the surface. When working and treating it is important to pay attention to a uniform absorption of the surface. Nonuniformities create "islands" that create both visual and functional constraints.

A sufficient primer ensures the uniformity. Absorbent materials must be "soaked" and "saturated" to be able to carry a secure seal. Before applying paints during renovation and beautification, the primer must be primed and completely dry.

Abrasion and tear resistance

Abrasion occurs on a table top during use. Therefore, many furniture and decorative paints are not suitable for sealing. When selecting, the abrasion resistance of the dried sealant layer must be considered.

A typical damage on sealed tabletops can be caused by lacquer breaks and cracks. Therefore, the table top should be checked for possible bending properties. Even for use insignificant plate deformations, for example, by supporting the seal can already damage. For mobile table tops, the viscosity properties of the selected finish must be adjusted. There are fewer and more tear-resistant types of lacquer.

Tips & Tricks

When using glazes, pay attention to their properties regarding textiles. An incorrectly selected glaze can "attract" lint made of sleeve or tablecloth fabrics electrostatically.
