Features & Benefits

• Ready-to-use powder binder composed of high-strength cements and special admixtures
• Contains no chlorides
• Mixed with water, Lampocem produces a paste with a plastic-thixotropic consistency which is easy to apply even on vertical surfaces, without any need for formwork
• A very fast setting time (about 3 minutes at +20°C) and, after curing, has the following property:
• Very high mechanical strength after only few hours
• Low shrinkage
• No loss in performance over a long period of time

Recommendations

• Do not use Lampocem for restoring deteriorated concrete structures (use Mapegrout Thixotropic or Mapegrout Fast-Set)
• Do not use Lampocem to anchor machines or bearing structures (use Mapefill)
• Do not use Lampocem for levelling, smoothing or repairing floors, walls or steps (use Nivorapid)
• Do not apply Lampocem to dry or dirty surfaces
• Do not mix Lampocem with more water than prescribed and do not add more water to the mix when it has begun to set
• Do not add lime, cement or gypsum to Lampocem
• Do not leave bags of Lampocem exposed to sunlight before use

Application

Preparation of the substrate

The surface must be solid, strong and free from dust and degraded or loose material.

Cavities formed for fixing must be roughened and thoroughly soaked with water.

This operation must be carried out very carefully, especially if the substrate is highly absorbent (mixed masonry, brickwork) and if it is exposed to hot sun.

Preparing the mix

While stirring, pour 1 kg of Lampocem into a container holding 200-210 g of water (20-21% of water to 1 kg of Lampocem) and mix manually with trowel or float to obtain a smooth mix with no lumps.

Lampocem can be prepared in larger quantities, in which case an electric mixer is recommended.

Given Lampocem’s fast setting time, prepare only amounts which can be placed within 1-2 minutes.

For mixing by volume, 4 parts Lampocem should be mixed with 1 part water.

The instructions for the preparation of the binder to be used for the creation of concrete samples for laboratory tests are reported in the "Technical Data" table below.

Applying the mix

Apply the Lampocem mix rapidly with trowel or smooth float.

Securing foundation bolts, hinges, tie-rods, etc.

Completely fill the appropriately prepared cavity with Lampocem and then insert the hinge, foundation bolt or tie-rod.

Finish off surface with trowel.

Securing sub-frames and window and door frames

Position frame and seal off anchor bolts with Lampocem.

Finish off surface with trowel.

Keep frame firmly in position for a few hours.

Stopping small water leaks

After preparing the mix, wait a few minutes before applying it so that the material warms up and begins to cure.

At this point, with gloved hands, force the Lampocem into the cavity and keep it pressed down until it has set.

Cleaning

Before it hardens, Lampocem can be cleaned from tools with water.

After setting, residues can be removed by mechanical means.

Consumption

1.8 kg/dm³ of cavities to be filled.
