Which jointing product should you choose?

Application and techniques / By Team ROMFIX

Brush-in sand and polymeric jointing sand

Suitable for narrow joints (≥ 1 mm), light loads and permeable bases

Polymeric jointing sand consists of fine sand mixed with a polymer binder. Choose weed-inhibiting brush-in or polymeric sand when:

You are laying blocks, concrete paving or clay paving with narrow joints.
The base is permeable, without cement stabilisation.
You want a cost-conscious solution for lightly loaded patios, paths or driveways.
You want joints that remain slightly flexible and partially self-heal.

Important:

The paving units must be completely dry, including their sides.
Do not use in joints wider than 3 mm.
Do not apply over an impermeable base such as a cement-bound build-up.

One-component jointing mortar

Suitable for patios, paths, gardens, pedestrian areas and hard-to-reach places

One-component jointing mortar is ready-mixed and only needs activation with water. Choose it when:

You want a user-friendly, error-free solution for domestic use and smaller projects.
The paving carries light to medium loads, such as gardens, patios or footpaths.
Weed control is difficult around street furniture such as letterboxes, lamp posts and benches that sweeping machines cannot reach.
You want to work in drizzle, which one-component mortars tolerate better.
You want a more environmentally friendly solution. ROMFIX Easy Fijn uses 98% natural raw materials and can even freeze in storage.

Important:

Apply only over a permeable base or over drainage bedding mortar with a bonding agent.
Ideal for domestic use, without professional equipment.

Two-component jointing mortar

Suitable for heavy loads, intensive use, public spaces, driveways and parking areas

Two-component jointing mortar consists of resin and sand that must be mixed. It is the strongest jointing product in our range. Choose it when:

The paving carries heavy loads from cars, commercial vehicles or intensive cleaning.
Durability and a long service life are essential.
You need a solution that is permeable to both gas and water.
You are using a ROMFIX foundation, drainage bedding mortar and bonding agent and want the full system warranty.
You need joints that withstand pressure washing and intensive street use.

Installation in accordance with our advice qualifies for our five-year system warranty. See the separate warranty page for details.

Cement-based paving jointing mortar

Suitable for impermeable applications, specific types of stone, finishing work or tiling

Choose a cement-based jointing product when:

The joints must not let water through, for example under a canopy or over an impermeable base.
The base is either fully impermeable or bonded drainage bedding mortar with a bonding agent. Other build-ups can trap moisture.
You are working with specific absorbent natural stones or on indoor projects.

Please note: Many types of paving naturally let water through. Cement-based joints can cause problems in these situations. Unsure? Use the ROMFIX jointing guide.
