Dear Sirs, Can this product be spray applied with an air cylinder compressor to external limestone walls. ? I have spray applied Thompsons waterproofing solution and other similar products and used G4 pond sealers previously Thank you kindly Regards Mark T 07801 236174

Assuming the substrate is clean, dry, sound and prepared in accordance with the technical datasheet, this product is suitable. We'd recommend thinning with Bonda G4 Thinners , this allows spray viscosity, however the degree of thinning depends on the equipment used and the operator. Due to thinning, it will be necessary to apply additional coats of Bonda G4 Damp Seal. We'd also recommend suitable respiratory protection such as an air-fed mask and PPE for the applicator.

Is this product suitable to seal an indoor exposed cob wall that I can then paint with a matt/silk emulsion paint.

While this product once fully dried can be sanded, washed down and painted, it has not be tested for this application to cob. We would recommend to test on a small area for compatibility and adhesion prior to full application.

Can i use this to seal interior plaster wall before painting with matt emulsion interior paint?

Assuming you are wanting to seal an area of existing, aged plaster due to an isolated and rectified damp issue, we would suggest something like Coo-Var Anti-Damp Paint would be more suited to this type of application. However, if you just have new/bare plaster that you do not have any dampe issues with and simply wish to prime/seal before painting or papering then Zinsser Drywall Pro 2 in 1 would be the more suitable option.

Can I plaster onto g4 damp proofing sealant?

ColourPicker Explained

In general we sort colours for products into 2 main groups - ‘Ready Mixed’ and ‘Tinted’.
Tinted colours will always be more expensive than Ready Mixed colours as they need to be produced at the time of order using a tinting machine dispensing colourant into a base*.
During busy periods, this means that tinted colours could take longer, for example – a ready mixed colour ordered on a 3-5 day delivery might arrive within 3 days, however a tinted colour might take the full 5 days to arrive.

To find Ready Mixed colours, search "ready mixed" or select the Ready Mixed 'colour chart'. To see Tinted colours select a colour chart such as RAL, BS, NCS, etc. or search for a colour/hue to see available or related options.

To ensure fair pricing, we split colours into ‘Price Bands’ to group together similar priced colours. If you wish to search for the cheapest tinted colours, always select Price Band 1.

We make every effort to list all available colours, however we also offer a colour match service which can be accessed by contacting our Technical Team on 0113 245 5450 (option 2) or emailing [email protected]

*Colours are sold in the nearest tin size but actual paint volume per tin may vary up to 10% depending on colour
