CE marking as conforming to EN 1504-3 (system 2+) and the European Construction Products Regulations.

How to prepare the surface when applying the screed?

The surface must be hard (with a tensile strength of more than 1 N/mm2) and clean, free from grease, oil, paint, residue, mortar, loose material, sand, dust or any other contaminant. We recommend that the surface be properly prepared, preferably by mechanical means (sandblasting, intensive brushing, etc.). Surfaces that are very smooth and/or slightly porous should be treated in the same way, preferably mechanically, so that they become sufficiently rough and porous. When repairing imperfections and patches, the surface should be cleaned beforehand and any loose material removed if necessary using a chisel so that the edges of the area to be treated are left straight.

When repairing cracks or fissures, open them accordingly in their width, length and depth so as to obtain vertical cuts. Leave cross sections and wash the area so that it is treated with water.

Soak highly absorbent surfaces with water - avoiding mixing - and then wait until the surface takes on a matt appearance before applying the product.

Instructions

PREMHOR STREET should be mixed with water and stirred with an electric mixer at slow speed until a homogeneous mixture without lumps is obtained. One 25 kg bag of dry mix is mixed with 3.25 - 3.50 l of water. Once the mixture is ready, lay the product immediately. The product should not be applied for 5-10 min. after mixing. The open time for handling the product is not more than 15 - 20 min. Do not prepare more solution than you could apply in its open working time.

How to apply concrete screed?

The paste obtained from PREMHOR STREET and water should be applied to sections that need repair. Use a trowel to fill voids, blemishes, patches, cracks, etc. Once you have spread the paste, wet the trowel and use it to smooth.

You should not try to apply a layer of PREMHOR STREET exceeding 3 cm each time. Apply several coats if you need a thicker layer. Once you have applied PREMHOR STREET make sure it is kept wet by spraying it with water over the next few hours.

Special applications and where can we apply quick-setting cement mortar?

To strengthen and increase adhesion to certain surfaces, PREMHOR STREET may be mixed with a solution of two parts water and one part CRYLADIT. For a bag of PREMHOR STREET will need approximately 1.75 - 2.00 l of water and 1.50 l CRYLADIT. First of all, mix the water with CRYLADIT and then add this mixture to PREMHOR STREET. You can also use this mixture of water and CRYLADIT in the mortar for adhesion.

When the high degree of adhesion is due to the special nature of the application (repairing surfaces subject to heavy and intense traffic or structural concrete, etc.), we recommend applying primer to the surface when it is completely dry - use products such as TECMA PAINT AD and then apply PREMHOR STREET while the primer is still dry.

Special recommendations when laying concrete screed

• To apply the product correctly, do not mix more PREMHOR STREETthan necessary. Pay attention to the suitability after mixing the paste and make sure that the mortar for adhesion is fresh.

• Do not apply to frozen or frozen surfaces
• Moisten the surface before application PREMHOR STREET
• Make sure that when you apply PREMHOR STREET it is kept wet over the next few hours, particularly in warm weather.
