Screed Additives
Our screed additives are ideal for applications where rapid drying times are required and high early strengths. This includes underfloor heating, internal and external applications.
Products
AptiScreed – a screed additive for enhanced drying
AptiScreed is designed to provide low shrinkage and high early strengths to semi-dry screeds that allow foot traffic after 12 – 24 hours and high levels of compressive and flexural strength after 7 days.
Applications
AptiScreed is a high specification plasticising and water reducing admixture for cementitious semi-dry screeds. It is recommended for use in internal and external screeds on which ceramic, natural stone, parquet, resilient, carpet, etc. is to be applied.
Benefits
- Low shrinkage.
- Allows foot traffic after 12-24 hours.
- High mechanical strengths at 7 days.
- Produces a Cat A, C40, F7 Screed.
- Compressive strengths of up to 60N/mm² can be achieved.
- Ideal for underfloor heating, allow 15 days curing prior to commissioning heating.
- Internal and external applications.
- Improved finishing from action of superplasticiser.
- Low odour, low VOC content
AptiScreed Max – a screed additive for ultra fast drying
AptiScreed Max is a unique, innovative liquid screed admixture combining next generation technology for rapid drying times and high early strengths.
Applications
AptiScreed Max is a liquid admixture for semi-dry screeds which has been specifically developed to provide rapid drying times, high early and ultimate compressive and flexural strengths in bonded, unbonded and floating screeds. It is ideal for underfloor heating, internal and external applications.
Benefits:
- High early compressive and flexural strengths.
- Allows foot traffic after 24 hours.
- Very rapid drying times.
- Produces a Cat A, C40, F7 Screed, allows thinner screeds to be laid without compromising strengths.
- Compressive strengths of up to 60N/mm² can be achieved.
- Ideal for underfloor heating.
- Internal and external applications.
- Bonded screeds from 20mm and 35mm for unbonded screeds.
- Improved finishing from action of superplasticiser.
- Low odour, low VOC content.
AptiScreed Max Powder – a screed additive for rapid drying and high early strengths
AptiScreed Max Powder is a semi-dry screed additive which has been specifically developed to provide rapid drying times, high early and ultimate compressive and flexural strengths in bonded, unbonded and floating screeds.
Applications
AptiScreed Max Powder is a unique, innovative screed additive combining next generation PCE technology for rapid drying times and high early strengths. It is ideal for underfloor heating, internal and external applications. AptiScreed Max Powder is also suitable for pumped screeds.
Benefits
- Will allow foot traffic after 24 hours.
- Produces a Cat A, C40, F7 Screed, allows thinner screeds to be laid without compromising strengths.
- Bonded screeds from 20mm and 35mm for unbonded screeds.
- Improved finishing from action of superplasticiser.
- Low odour, low VOC content.
AptiScreed P – a powder screed additive for enhanced drying
AptiScreed P is a powder admixture formulated to provide rapid drying time and improved strengths when used in traditional sand/cement screeds.
Applications
AptiScreed P is designed for use in applications where the screed is bonded to the substrate, un-bonded or floating. The standard screed mix of cement and sand mixed in the ratio of 1:3-5 is used for creating a level layer to receive the installation of the final floor finish such as tiles, wood, linoleum, vinyl etc. Traditional screeds are generally suitable for use in hospitals, schools, retail, homes etc. AptiScreed P is ideal for use in screeds covering underfloor heating systems.
Benefits:
- Rapid drying enabling earlier application of floor coverings.
- Can be lightly trafficked after 24 hours.
- Suitable for all normal screed applications including over underfloor heating.
- Supplied in a water-soluble sachet. Easy addition on site with no measuring or mess.
- Produces screeds which comply to ISCR Cat A or B depending on mix design.
- Compressive strength: >25N/mm².
AptiScreed Plus – a highly efficient plasticiser and water reducer
AptiScreed Plus is a highly efficient plasticising and water reducing admixture for cementitious semi-dry screeds. It has been specifically developed to provide tough wearing screeds with a hard, durable surface finish. Improved strengths permit a minimum screed thickness of 35mm when laid onto insulation or polystyrene.
Applications
AptiScreed Plus is recommended for use in the production of heavy duty internal and external screeds with high mechanical performance. It is also suitable for underfloor heating, internal and external applications.
Benefits
- Production of heavy duty screeds with high compressive strengths.
- Improved mixing and surface finish due to highly efficient plasticising action.
- Potential to produce a CAT A, C40, F7 Screed using the correct mix design.
- Reduced screed thickness to a minimum of 35mm on insulation or polythene sheet.
