Super Hydrophobic Exterior Coating
OSCAR Insulate & Protect is our own brand of super hydrophobic brick sealant, designed to stop water absorption by bricks, protect the brickwork and pointing, and help prevent water ingress into cavity wall insulation.
About the Product
We believe that super hydrophobic coatings will become the benchmark for the building trade in the future, and we are proud to launch our own product — OSCAR Insulate & Protect — to raise the profile of a new era in exterior coating technology.
The UK faces significant challenges in retrofitting its housing stock to meet government targets for fuel poverty and carbon reduction. These challenges bring exciting opportunities for innovative coating technologies like Insulate & Protect. By working alongside existing energy saving initiatives, our products keep buildings dry — and dry buildings mean dry insulation, reduced heating costs and improved living conditions for occupants.
Once applied, these coatings last between 10 and 20 years, providing many years of comfort as well as reduced maintenance and upkeep of your property — a win-win all round. They come with long-term manufacturer's guarantees and are proven to withstand all climatic conditions.
Our passion for these technologically superior coating products is only rivalled by our commitment to quality, compliance and customer service. We provide a full technical applicator course for our member firms, including full back-up service, training and monitoring to ensure you get the best possible service nationwide.

The Science
Moisture in building materials is a key driver to energy loss. Wet materials transfer heat much quicker than dry materials. Tests have shown that a damp content of 5% in a plain brick wall can lower the insulation performance by a staggering 50% — and we are no strangers to the wet weather we get in the UK.
By keeping walls dry, OSCAR Insulate & Protect helps to improve the overall thermal efficiency, keeping your house warmer, with less costs and a reduced carbon footprint. The super hydrophobic coating causes water to bead and roll off the surface rather than soaking in, while remaining fully breathable so that moisture vapour can escape from within the building fabric.
Key Benefit
A 5% damp content in a plain brick wall can lower insulation performance by 50%. Insulate & Protect keeps your bricks dry, so your cavity wall insulation stays effective — reducing heat loss, lowering energy bills and improving comfort.
Thermal Efficiency Improved
Dry walls insulate better than wet walls. By preventing water absorption, Insulate & Protect helps maintain the thermal performance of your property's external fabric.
Product Range
The OSCAR Insulate & Protect range includes four specialist products, each engineered for specific building materials and surfaces. All products are super hydrophobic, fully breathable and proven to withstand UK climatic conditions.
A specialist penetrating crème that deeply impregnates masonry, creating a super hydrophobic barrier that reduces water absorption by up to 96.3% while remaining fully breathable.
An advanced facade coating system that combines super hydrophobic water repellence with thermal insulation properties, reducing heat loss through exterior walls.
A super hydrophobic water repellent treatment designed for porous building materials, causing water to bead and run off the surface rather than soaking in.
A specialist wood treatment that penetrates timber to provide long-lasting water repellence, protecting exterior woodwork from moisture, rot and decay.
For Member Firms
OSCAR Onsite provides a full technical applicator course for member firms, including full back-up service, training and monitoring to ensure the best possible service nationwide.
A comprehensive training programme teaching member firms the correct process, methodology and compliance for applying Insulate & Protect products to the highest standard.
Every application is technically monitored and recorded, ensuring all areas of the property are covered correctly and meet OSCAR's quality standards.
Homeowners receive documented confirmation that the application has been carried out to OSCAR standards, giving complete confidence in the quality of the work.
Quality & Compliance
This type of super hydrophobic product has been rigorously tested by UKAS testing laboratories — and the results speak for themselves.
This type of masonry coating has been rigorously tested for durability, thermal insulation, property breathability and water repellence by UKAS testing laboratories. OSCAR Insulate & Protect is formulated to the same exacting standards.
Energy Savings Trust is an independent organisation dedicated to promoting energy efficiency and sustainability, setting benchmarks that products of this type are designed to meet.
NRG Expert — a world-leading energy consultancy whose Managing Director is listed on the London Academy of Experts — reviewed the relationship between hydrophobic coatings, water absorption by bricks and heating energy loss, and agreed that keeping walls dry is likely to improve the U-value of the home.
Oscar Onsite Insulate & Protect manufacturers continually test to demonstrate no evidence of water penetration, no deterioration in performance, and no cracking or deformation of the brickwork.
Our Process
From enquiry to certified application, our monitored process ensures every surface is correctly treated and documented.
Contact OSCAR Onsite to discuss your property. An accredited OSCAR surveyor will assess the building to confirm suitability and identify all areas requiring treatment.
Our trained applicators prepare all surfaces — cleaning, repairing pointing and ensuring the substrate is ready to receive the super hydrophobic coating for maximum adhesion and performance.
The Insulate & Protect coating is professionally applied to all agreed elevations by our trained and monitored member firms, ensuring full and even coverage across every surface.
Every application is technically monitored and recorded to ensure all areas are covered correctly. You receive documentation confirming the application meets OSCAR standards.
