1. PCT UK Retanol Xtreme

Additive for installing extremely quick drying, high early strength, low shrinkage and low tension bonded, un-bonded and floating cement floor screeds. Enhances pumping and workability enormously. Retanol Xtreme screed does not require curing under polythene, nor the addition of fibres to the mix.

2. PCT UK ZE Bonding Agent

PCT ZE BONDING AGENT can be universally used to bond all cementitious screeds to suitable substrates. The simple mixture of 25 kg of Portland cement with the addition of 150 ml PCT ZE BONDING AGENT is unique, and is suitable for internal and external applications. High moisture resistance with no re-emulsification once dried. PCT ZE BONDING AGENT provides a guaranteed and extremely strong bond between the cementitious substrate and the subsequent new screed. This product is also suitable as a bonding agent for resin damp proof membrane coatings provided they are installed as per the manufacturer's recommendations, adequately sand blinded and fully cured. PCT site inspection and technical assessment is recommended.

3. PCT UK Qualimeter

QUALIMETER® is an innovative clear liquid additive for screed, supplied in measured sachets of 30 ml or 10 / 20 litre containers. It greatly enhances workability and pumping by reducing the air pore content in the screed matrix, unlike traditional plasticisers.

4. PCT UK Hydranol

Innovative and easy to use, powdered screed reinforcing and drying agent, supplied in measured sachets for making low-shrinkage, low-tension cement screeds guaranteed to dry in 28 days. Enhances pumping and workability enormously.

5. PCT UK Retanol EKA BW

Additive for installing fast track low shrinkage and low tension bonded, un-bonded and floating cement floor screeds. Enhances pumping and workability enormously. Guaranteed performance and drying time of 7, 14 or 21 days depending on the mix design.

6. PCT UK Risol Plus

Innovative and easy to use, liquid screed reinforcing agent, for making low-shrinkage, low-tension cement screed. Enhances pumping and workability enormously. Supplied in 20 litre containers.

Adhesion Pull Off Test Report for Resin

This is an independent resin pull off test report on Retanol Xtreme screed compiled by Resdev Ltd (a leading UK manufacturer of Polyurethane resins). Resdev concluded that Retanol Xtreme screed was at least as strong as concrete.

Compressive and Flexural Strength Test Report

A Compressive Strength Test is a mechanical test which measures the maximum amount of compressive load the Retanol screed can bear before fracturing. Retanol Xtreme can achieve compressive strengths of up to 60 N/mm2 depending on aggregates and the amount of cement used. A Flexural Strength Test is also a mechanical test which measures the tensile strength of the Retanol screed. Retanol Xtreme can achieve flexural / bending tensile strengths of up to 8 N/mm2 depending on aggregates and the amount of cement used.

Retanol Approved Cement List

To achieve the best results with Retanol screed additives, PCT Chemie recommends that the following types of cement should only be used: Type: Portland cements CEM I, or Portland composite cements CEM II (for example A-L, A-LL, B-L, B-LL). Please see the PCT Cement List for further information Class: 32.5 N + R/42.5 N + R (note that 52.5 is less suitable for screeds due to its higher strength which can increase the risk of cracking and deformation) Quality: Use standardized and QC-monitored cements Only the cement type categories highlighted in green in the following cement clearance list should be used when mixing Retanol screeds.

Retanol Xtreme Point Load Test Report

This is a point load test report on a Retanol Xtreme Fine Concrete screed installed at Cineworld in Speke (Liverpool). This screed was used as a direct substitute for concrete where concrete pours were deemed neither practical nor possible in certain areas. The Retanol Xtreme Fine Concrete dosage comprised the standard mix of 400ml of Retanol Xtreme and 62.5kg of cement mixed in a standard screed pump of 250 litres gross capacity, but with 20% of 6mm stone chippings added to increase the compressive strength of the screed to 60 N/mm².
