Larsen Streetscape GPM Eco DIRECTIONS FOR USE:

PREPARATION

All surfaces must be sound, clean, and free from any loose or friable material. For paving applications, Larsen GPM Eco should only be used on rigid constructions. On pointing application where previous mortar has been raked out, ensure all dust has been removed and joint depth is at least 1.5 times width. All joints must be saturated with clean water but free from standing water.

MIXING

Mix each 25 kg bag with 4.0-5.0 L clean water. Larsen GPM Eco should be mixed with the correct amount of water using a mechanical method, i.e. low-speed drill and mixing paddle. Mix for a minimum of 3 minutes, allow to stand for 2 minutes, then remix. To check consistency, fill the tube of pointing gun and shake, the mortar should ‘hang’ from the nozzle. Do not mix more product than can be used in approx. 40 minutes. Do not add more water or ‘wet-up’ mortar which has begun to set.

Larsen Streetscape GPM Eco APPLICATION

Larsen GPM Eco can be applied to joints from 5 mm wide and up to 150 mm deep. Joint depths should be ideally be a minimum of 1.5 times joint width. After filling pointing gun, place nozzle as deep as possible into the joint and inject the mortar. Fill the joint from the bottom and allow to slightly overfill joint. Allow mortar to stiffen before tooling as required. Any mortar remaining on the surface of the masonry or paving unit should be washed off before it has set. Use of excessive water and/or ‘wash-boys’ to clean the face of the joint and paving or masonry unit is not recommended as the high amount of water can result in efflorescence. Where colour is critical, always carry out a trial area of at least 1m2 and ensure the same batch of material is used. If in doubt contact our technical department for more advice.

RESTRICTIONS

Not suitable for use in flexible or unbound constructions. Not suitable for filling of live cracks or movement joints. Ambient and substrate temperatures should be above 3°C during application. Slight batch to batch colour variations may occur. Always work with the same batch of material where possible or premix batches to reduce visible variations. Fresh mortar should be protected from frost and inclement weather. When ambient or substrate temperatures are below 10°C, allow extra time for the material to harden. Efflorescence and Limebloom are natural phenomena affecting all cement based materials. Their occurrence are transitory and in no way affect the ultimate performance or durability of the product. Occurrences can be minimised by avoiding working in cold and damp conditions, protecting fresh mortar from excessive water during early age from clean-up operations and unfavourable weather until sufficiently cured to withstand them.
