How to Apply UltraScape Flowpoint Premium Paving Grout

UltraScape Flowpoint Premium is a market-leading slurry grout designed for fast, reliable application and long-lasting results. With its rapid-set, high-fluid consistency, this paving grout creates strong, rigid, and void-free joints that conform to the strict standards of BS 7533. Ideal for town centre pedestrian areas, pathways, patios, and carriageways, it works with a wide range of paving materials including natural stone, concrete flags, clay pavers, and porcelain paving.

Pre-mixed and supplied in a dry pack, Flowpoint Premium only requires water on-site, making it simple and efficient to use. It can fill joints from 5–50mm wide (minimum 20mm deep, up to 200mm in one application) and achieves a compressive strength of 49.6N/mm². With its rapid-setting formula, the mortar is traffic-ready in no time—foot traffic within 1 hour and vehicular traffic in just 4 hours (at 20°C).

Step-by-Step Application Guide

1. Preparation

  • Ensure all joints are clean, dry, and free from debris.

  • Remove any ponded water before starting.

  • Pre-soak the paving surface and joints thoroughly, keeping them wet throughout the grouting process.

2. Mixing the Slurry Grout

  • Mix one 25kg bag with 4.25 litres of clean water for 3–5 minutes.

  • Blend until smooth and lump-free.

  • Apply immediately after mixing—do not store, remix, or add more water later.

3. Applying the Paving Grout

  • Using a neoprene squeegee, spread the slurry grout across the surface.

  • Work the mortar into the joints, ensuring they are fully filled.

  • Reapply to any joints that slump, topping up as needed.

  • Remove excess grout as you go and keep the surface damp with a fine water spray.

4. Cleaning the Surface

  • Once the mortar has set enough, clean the paving thoroughly with a brush and plenty of clean water.

  • Ensure all residue is removed to prevent staining.

5. Final Checks & Safety

  • Always carry out a small test area first to confirm stone compatibility.

  • Wash tools frequently during use.

  • Only mix the amount you can apply within 4 minutes.

  • Wear protective clothing—wet cement can cause burns.

  • Be aware: cooler weather slows curing, while warmer conditions accelerate it.

UltraScape Flowpoint Premium paving grout is a trusted solution for both small residential patios and heavy-duty commercial paving schemes. Its slurry grout application method ensures durability, speed, and a professional finish every time.
