Flowpoint Product & Technical Data
- Rapid setting with exceptional bond strength
- Shrinkage compensated
- Bond (adhesion strength): 1.5N/mm² after 28 days
- Compressive strength: 49.6N/mm² after 38 days
- Flexural strength: 7.1N/mm² after 28 days
- Tensile strength: 3.91N/mm² after 28 days
- Conforms to British Standard - BS 7533
- Ideal for large-scale projects
- We advise using Pro-Prime to prime the back of your slabs to increase bond strength and prevent stains & efflorescence
- Please note: Flowpoint is not recommended for some darker limestones, such as black limestone, as slight oxidisation may occur. Contact our expert team for advice on the ideal grout for darker limestone.
- Shelf life: 8 months from the date of manufacture (printed on the bucket) if unopened and stored correctly. Using the product after this period may increase the risk of an allergic reaction.
How Do You Mix and Apply Flowpoint Fine?
- Ensure you have somewhere to push excess slurry grout, such as an area of lifted grass. Never push excess Flowpoint into drains — it is a rapid-setting grout and will create a permanent blockage.
- Check that paving slabs and joints are free from dirt, debris, and pooled water. If needed, use a leaf blower to remove water.
- Spray slabs and joints with clean water so they are damp, but not flooded.
- Add 3.4 litres of clean water into a bucket, then pour in the bag of Flowpoint Fine Paving Grout from the tub.
- Mix with a paddle mixer or by hand for 3–5 minutes until smooth and lump-free.
- Ensure paving slabs are still damp. If not, mist lightly, then immediately apply the grout using a neoprene rubber squeegee, carefully pressing the Flowpoint into the joints.
- Monitor temperature closely — Flowpoint sets within 15 minutes at 20°C. Hotter weather accelerates setting; cooler temperatures slow it down. Remember paving surfaces can be hotter than air temperature.
- Move the grout across the paving surface to top up any joints where the mortar has settled.
- Once joints are full, use a rubber squeegee to remove excess grout from slab surfaces. Keep slabs misted to prevent the grout from hardening.
- Use a brush with a little water, or alternatively a pressure washer or sponge machine, to remove any hardened grout from the paving surface.
- After ~30 minutes, when the mortar has partially set (do a finger/thumb test), clean the paving surface to remove spots and prevent staining. Repeat with clean water as needed.
- Once clean and dry, the patio is walkable after 1 hour and can take vehicular traffic after 4 hours.

Flowpoint Fine Rapid Set Paving Grout - Charcoal
“Best Paving Grout for Porcelain Tiles & Narrow Joint Widths”
New to the market, UltraScape Flowpoint Fine Charcoal Paving Grout is a fast setting slurry grout supplied in a 20kg tub. It fills joints from 2–50mm with a flowable, easy pour and apply consistency, starting to set in just 15 minutes. Unlike Flowpoint Standard, Smooth, or ECO, which have visible aggregate, Flowpoint Fine delivers a super smooth finish with no visible aggregate.
Ideal for commercial paved areas or domestic patios where a rigid, bound, and void-free joint is required. Perfect for driveways, patios, town centre pedestrian schemes, pathways, and carriageways — especially when early trafficking is needed. Conforms to BS 7533. Suitable for natural stone, concrete flags, porcelain tiles, and clay pavers.
Flowpoint Fine is also ideal for creating a modern indoor-outdoor look. Its smooth, rapid-set, cement-based formula replicates internal tiling grout, so it’s perfect for seamless transitions from kitchens or conservatories to your garden.
Unlike traditional paving grouts, Flowpoint Fine is a slurry grout — faster to apply, less labour-intensive, and kinder on your knees. Simply mix with water, pour across slabs, squeegee into joints, and clean down to reveal strong, durable, weed-free joints lasting up to 40 years.
