Fast-setting natural cement mortar for marine masonry above and below the waterline (incl. tidal/scour zones).

What it is

Dry, ready-mixed blend of Prompt Natural Cement and selected natural sands—no Portland cement, no synthetic polymers, no lime (so no carbonation required).
Low–medium strength natural cement mortar; lowest strength within the P-series, engineered to balance early set with substrate sympathy.
Technical behaviour broadly comparable to an NHL 5 mortar but with higher compressive strength and lower capillary water absorption.

Where it excels

Tidal, splash and submerged zones in fresh or saltwater where rapid set reduces washout and scouring risk.
Projects demanding cement-free (OPC-free) durability and natural sulphate resistance inherent to PNC chemistry.
Conservation/renovation where a moderate, not brittle strength is appropriate for mixed historic masonry.

Performance at a glance

Working/open time: ~55 minutes at 17 °C (ambient & suction dependent).
Set: Speedy initial set to resist tidal action; progression to service strength with proper curing.
Shrinkage risk: Minimised relative to many rapid-set systems.
Colour: Natural tan, pigment-free (tone varies with curing and exposure).

• Need natural cement-free, slower set above water? See Roundtower Marine L4.

Coverage & yield

25 kg → Approx14.5 L fresh mortar.
Approx. 1.5 m² of joint at 10 mm depth (actual yield varies with joint width/depth and substrate texture).
On-site trials recommended to confirm consumption.

Application essentials

Prep: Rake out to sound arrises; remove salts/bio-growth; pre-dampen.
Mix: Add clean water gradually to a cohesive, plastic consistency; do not over-water.
Place/Finish: Compact fully; finish as the mortar firms.
Curing & protection: Shield from frost, rain, direct sun, drying winds and washout through initial set; continue gentle curing.
Temperature window: +5 °C to +30 °C (consider wind-chill/radiant heat). Avoid if freezing is forecast during early cure.

We always endeavour to take into consideration everyone's delivery needs.
Please ensure your delivery location has;
• Level area with no sharp inclines/declines.
• No Grass/Gravelled areas as pallets cannot be moved.
• Open access for Curtain sided Lorries.
• Whilst our drivers are instructed not to take their vehicle off the roadway to
make deliveries, our driver will make every effort with your delivery to meet your requirements.
• If you require the driver to leave the roadway, it will be at your own risk.
• Where a pathway is cemented / tarmacadam our drivers will do their best to bring a pallet to customers preferred drop on their premises.
• If it is gravel and not practical for a pallet truck to run on it, the driver is obligated to drop the pallet at nearest kerb side.
• The drivers are not obligated to place the pallets into stores, garages and a warehouses.
