WHY USE A PRIMER AND ADDITIVE IN YOUR TILING INSTALLATION?

Primers

A primer is a liquid product, which can be either latex, epoxy or polyurethane based,
and is used to create better adhesion onto the substrate before tiling or screeding
commences. The function of a primer is to prepare the surface and increase the bond
of the adhesive, screed and waterproofing compounds onto the surface.

Substrates may be porous or impervious, smooth or rough, or dusty and powdery.
Without applying a primer, the substrate may either draw the liquid from the adhesive or
screed mix (porous surfaces), prevent the adhesive or screed from bonding onto the
surface (dusty or powdery surfaces), or be too smooth or dense for the adhesive or
screed to form an adequate bond onto the substrate (smooth, impervious surfaces).

 

Incorrect or inadequate surface preparation can adversely affect the integrity of the  
installation and may lead to an installation failure. The solution is to use a primer.

 

TAL provides a range of primers to prepare the surface prior to the application of tiling
adhesives, screeding and waterproofing compounds. The TAL range of primers
consists of TAL KEYCOATTAL FLOOR PRIMERTAL FLOORKEYTAL EPOXY PRIMER 
and TAL SUPERPRIME.

 

Additives

An additive is a liquid product made with latex and is designed to be used as a water
substitute in the cement-based adhesive and grout mix when tiling or grouting external
areas, wet areas, high traffic areas and areas where some flexibility is required. TAL’s 
range of additives includes TAL BOND and TAL SCREEDBINDER.

TAL BOND additive improves the bond strength, flexibility and water-resistance when
added to cement-based adhesives and grouts.

It is important to use an additive when installing tiles in wet areas, such as showers,
and exterior applications. Additives make the tile installation less susceptible to water
penetration and also increase the flexibility of the adhesive and grout.

 

When using an additive in the adhesive or grout mixture, it is important to use the full
amount of additive as stipulated in the instructions on the packaging. Do not dilute
the mix with water as diluting the latex will compromise the flexibility and
water-resistance of the adhesive or grout. 

TAL SCREEDBINDER additive improves the bond strength and flexibility when added to 
TAL SUPERSCREED, which is used to level imperfections in flooring surfaces. When
mixing TAL SCREEDBINDER with TAL SUPERSCREED, the screeding compound can
be used as a protective barrier over ceramic tile heating elements.
