Builtex Mesh 1 × 50 m GR50 is a medium-weight fiberglass mesh, developed to reinforce continuous microcement coatings, especially in base layers. Its flexible and resistant structure allows it to absorb substrate tensions, preventing the appearance of cracks and improving system stability. This mesh is essential in microcement systems on deformable surfaces or where expansion is expected. It is part of the Builtex reinforcement family, recommended for demanding professional applications.
- Substrate preparation: the surface must be clean, dry and level. Apply appropriate primer depending on the type of substrate (PRIMACEM PLUS or ACRICEM).
- First coat of base microcement: apply a uniform coat of MICROBASE or similar.
- Mesh placement: spread the Builtex mesh over the still fresh coat, without folds or overlaps.
- Embedding: press lightly with a trowel or roller to ensure good adhesion.
- Second coat of base microcement: apply after drying, completely covering the mesh.
- Continue with the system: once dry and sanded, continue with the microcement decorative cycle.

Frequently asked questions about Toptools
What tools and accessories does the Toptools range include?
It brings together professional tools for applying microcement and decorative concrete: trowels, roller handles and refills, mixing rod, graduated jug, aluminium profiles, Builtex reinforcement meshes and Imacem® moulds for printed concrete, among others.
Which roller do I need for each varnish?
The DSV refills are designed for Topsealer® DSV two-component varnishes and the WT ones for the Topsealer® WT line. Both have a 4 mm pile and fit clip handles of the same width (180 or 220 mm).
What is Builtex mesh used for?
It is an alkali-resistant fibreglass mesh that is embedded in the first, still-fresh base coat of microcement and covered with a second coat. It reinforces the system and reduces the risk of cracks on floors and walls.
Which trowel should I choose for the microcement finish?
The Atenea and Zeus trowels and the carbon trowel are designed for finishing coats: they allow smooth, mark-free polishing, avoiding the burnt effect on floors and walls.
How are Imacem® moulds used?
They are flexible polymer moulds for stamping fan, cobblestone or tile patterns onto fresh printed concrete. Apply release agent to the textured face before placing them and remove them carefully so as not to deform the relief.
How do I clean and care for the tools?
Clean them with water (and soap for rollers, trowels and jug) right after use, before the product dries. Store rollers upright, and trowels and moulds flat, all in a dry place protected from sunlight and knocks.
