Stoneguard is a single pack, water dispersed fluoropolymer based coating which provides an invisible protective barrier.
Use on: Brickwork, stone, concrete and other porous mineral surfaces Use where: Internal/External Type of job: Ideal for water-repellent treatment of brick and stone buildings – especially for listed buildings – and to give oil resistance to driveways, parking bays and paved areas, factory walls, aircraft hangars and other surfaces vulnerable to oil and liquid penetration, atmospheric pollutants and other contaminants
Approximate coverage: 5L 70 - 100m2 subject to porosity and conditions Special features: Extremely durable and long lasting, prevents surface erosion caused by freeze-thaw cycles, retains breathability of construction materials, does not affect look or characteristics of treated surface
Application temperature: 8oC - 40oC Number of parts supplied: 1 Cure time: Touch dry - 30 mins Withstands rain within 3 hours Full chemical cure - 24 hours Priming required: No

Remove all loose, friable or flaking material and any fungal or algae growth. Ensure the surface is clean, dry and free of oil or other contamination. Wash thoroughly with clean water and allow to dry. Any repair work should be complete before application of Stoneguard.
A single thorough coat is normally sufficient. Depending on the size and evenness of the surface to be treated, Stoneguard may be applied by brush, roller (if the area is very flat), mop or coarse spray. Always start from the bottom of the wall. Fine spray should not be used and precautions must be taken to prevent inhalation of airborne droplets. Any pooling should be brushed out. If using a spray, use a coarse spray and apply using HVLP equipment.
Ensure the surface is completely covered.
If the surface is very porous, a second coat may be required which must be applied after a minimum of 30 mins.
Tile grout sealing – apply Stoneguard over entire tiled area with a brush or roller, re-coating after 1 hour. Avoid contact with water for 24 hours, then remove residue from glazed tile surfaces with soap and water.
Product QuestionsI have a stone cottage in the Yorkshire dales. It is beset with random dampness problems particularly around some of the window openings. Will stoneguard work in exposed situations?
what sort of life does it have?
If I need to redo the render around the window frame/reveal joint can I reapply and will it bond to previous coat
If it doesn't prove effective enough and I need to resort to a different solution can I apply a waterproof renderQuestion by: Ian Munro on 27 May 2015 13:22:00Ian,
Many thanks for your valued question.
Stoneguard will work in exposed conditions without a problem – that is what is mainly designed for.
The way this product actually works is completely different from the standard surface sealers. Stoneguard is based on the very latest water-borne technology and forms a water proof barrier beneath the surface and when this product was first brought out it was guaranteed for life. This will last for the term of the actual structure of your substrate. This also creates an effective barrier against surface efflorescence of stone, brick and concrete
You can reapply the stoneguard to a new render without a problem – you may have to abrade the actual existing surface to provide a key for a new render coat to adhere to this.
You should be able to apply a water proof render coat over the top of this but I would suggest that this product won’t require this. Simply ensure that the substrate is sufficiently cleaned and prepared and any cracks are repaired and this product will offer you a long term solution to your problem
Compatibility with other products will depend on their chemical structure. If you have any queries or products in mind then please feel free to ask.Answer by: Stuart White (Admin) on 28 May 2015 08:25:00
