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.

Features and benefits of Larsen FJM

  • Low shrinkage
  • Frost resistant
  • Colours: Natural, Charcoal, Buff & Mid Grey
  • Conforms to BS 7533

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. Larsen PS Priming Slurry is ideal and part of the Larsen Streetscape System, click here for Larsen PS.

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. 

Technical information

Size 25kg multi-walled paper bags
Coverage 13.6L per 25kg or approximately 7-10 square mtrs per 25kg bag
Compressive strength >40MPa
Joint widths Suitable for 5mm–50mm
Joint depths Up to 200mm

How do I prepare for using Larsen FJM?

All joints to be grouted should be clean, free from grease, oils, dust and loose particles or any debris that may interfere with the adhesion. It is important to thoroughly saturate the paving, joints and bedding before grouting using plenty of clean water ensuring no standing water or puddles are left on the paved area or patio. Saturating the whole area will ensure that the grout comes off the paving slabs easily, but remains in the joints, this is incredibly important with highly textured or absorbent paving.

How do I mix Larsen FJM?

In a suitable container or bucket, mix 5 litres of water per 25KG bag, mix with a suitable mechanical mixer for a minimum of 3 minutes to produce fluid, batter type consistency. Where necessary a little less water can be added to produced a slightly thicker mortar for patio's and paving which have a fall built in. Please note that if you use additional water to make the product more flowable, the strength of the product will be reduced, and the product may settle or bleed. Do not re-wet or add additional water and re-mix grout which has started to 'go off'.

How do I apply Larsen FJM?

Streetscape FJM can be applied in joint widths of 5-50mm, and up to 200mm deep in one single pass. Do to its fluid nature it is important to ensure that none of the grout escapes into nearby drains or water courses.

Once mixed, Streetscape FJM can be applied either with a watering can into joints, or flowed over the entire area and squeegeed into joints. Care must be taken to keep the area moist at all times with a spray of water, never allow it to dry during the cleaning process, allow the fast set jointing mortar to firm up before attempting to clean the paving slabs.

How do I clean and wash off Larsen FJM?

Once the joints have firmed up spray the area with water, then using a squeegee or brush begin to work over the area taking care not to brush the material from the joints, keep wetting and cleaning the area until all of the mortar has been removed from the slabs, but remains in the joints. Ensure that you follow the instructions carefully on the bag, taking care to note the temperature - cold temperatures will mean the grout will remain softer for longer, high temperatures will mean the grout will go off faster. Once grouting of the joints is complete, protect the area from foot traffic for at least 1-2 hours, and vehicles for 4-6 hours.

What equipment will I need to mix, apply and wash-off Larsen FJM?

  • Neoprene Squeegee for application: click here to purchase a squeegee
  • A stiff bristle brush for stubborn/hard to reach areas
  • Soft brush for cleaning off
  • 110 paddle mixer
  • Transformer
  • Extension lead
  • Large bucket
  • Large measuring jug
  • Rubber float
  • Small trowel
  • Jet washer | Hose | or Washboy
  • Wellies
  • Sponge for cleaning around edges
  • Leaf blower for cleaning leaves or getting water out of joints
  • All simple items in every contractor’s kit!

Follow these tips to avoid any stains or efflorescence when using Larsen FJM:

  • Clean and dampen the paving joints and surfaces with water, remove any ponded water
  • Keep the paved area damp with a light misting of water throughout the application
  • Use a rubber squeegee to push the grout into the joints, and immediately remove any excess paving grout for the surface of pavers
  • Once FJM has begun to set, use either a squeegee or a brush and a little water to agitate the remaining grout on the surface of the pavers and remove any hardened mortar
  • After approx. 30 minutes of applying the grout (and once it has fully hardened, do the thumb test), clean the surfaces thoroughly to remove any spots and prevent staining
  • To avoid causes cracks and low spots when using Larsen FJM, don't clean your slabs off too early! Do the thumb test, if your joint is still slightly soft to the touch, it's too early, wait and hold your nerve. This is especially important during colder weather, you'll just wash half the material away out of your joints
