From £4.08 p/mLarsen Streetscape PS is a polymer modified cement based slurry specifically designed to meet the recommended performance characteristics of BS7533.
It is manufactured from a controlled blend of specially selected aggregates, cements, and synthetic polymers and only requires the addition of water to produce a high-quality priming slurry for use to improve bond strengths of natural stone setts and cobbles, flags, concrete and porcelain pavers to Larsen Streetscape FBC.
Coverage: 25kg will cover up to 19m²
Mixing ratio: 6.5L per 25kg
Easy to use
Brush apply
Not suitable for flexible conditions
Preparation:
The substrate (including sub-base and road base) should meet the requirements of the relevant part of BS7533 dependent on the type and level of traffic. All substrates must be suitable to receive the bedding as per current good working practices. All substrates for bonded constructions should be clean and thoroughly sound and free from oils, grease, dust, loose particles or any other contaminants which may interfere with adhesion. They should be pre-soaked but free from standing water.
Mixing:
Add ~26% water (approx 6.5L of water per 25kg) to achieve the desired workability. Mix with a suitable mechanical mixer for a minimum of 3 minutes. Please note Streetscape PS is designed to be used as a semi-fluid consistency at the above water ratios. If more water is added, the hardening properties of the product will be reduced. Do not try to remix or wet-up PS which has “gone off”
Application:
Streetscape PS can be applied by a stiff brush at a thickness of 1-2mm. When priming the base, the priming slurry should be fresh and wet when the Streetscape FBC is applied. When priming paving slabs, this should take place immediately prior to their placement on the Streetscape FBC bedding layer.
