Larsen Streetscape FJM Flowable Jointing Mortar
Larsen Streetscape FJM is a fast set, flowable, slurry paving grout ideal for grouting between all types of paving, such as granite setts, sandstone, limestone, porcelain, Indian Stone, Yorkstone and concrete slabs. Streetscape FJM comes in a handy 25KG bag and is simple to mix the pre-blended mortar on site with a large bucket and clean water to produce a high quality grouting mortar for rigid or bound paving methods. It’s fast to apply too, simply pour over the paving slabs and work into the joints with a squeegee, then wash off after the initial set to reveal solid joints which will last for year and stop weed growth. Larsens Streetscape FJM has a workable time of 15 minutes, can accept foot traffic in an hour and vehicles in 4-6 hours. For anyone concerned about slurrying a mortar across their entire, expensive paving, Larsen FJM has been developed so that it doesn’t stick to the paving, just in the paving joints!
Larsen Streetscape FJM has been specifically designed to meet the rigorous demands and recommended performance characteristics of BS7533 parts 4, 7 & 12.

We always recommend using a primer, that is brush or roller applied to the back and side of your paving slabs before placing on the mortar bed to ensure a secure bond and to reduce the chance of staining or efflorescence.

Restrictions
Do not use Streetscape FJM in an unbound or flexible construction, should not be used below 3 °C. The surfaces of paving or substrate should not be frozen and fresh grout should be protected from inclement weather or freezing until required strength is achieved for damage not to occur. Movement joints may be required in ridged/bound constructions and should be laid out at the design stage. The flooding application should not be used with very porous paving blocks, the watering can method is recommended here. It is imperative that Streetscape FJM rapid set jointing mortar is removed from paving slabs before it has fully hardened to prevent staining, hardened grout will be very difficult to remove from the surface of the pavers.
