Technical Data


Application Tool Roller or Trowel
Suitable Substrates Existing well adhered paint coating, Render, Plaster, Building Board
Dilution Maximum 2% clean water
Coverage 2-3kg per m2 or 1.4-2.1m2 per litre
Application Temperature 5℃ - 25℃ for a minimum of 24 hours
Humidity Temperature Less than 85%



Preparation


Make good cracks and structural defects.

All surfaces must be clean, dry and free from algae, lichen & other growths. Any faults in the substrate/structure, particularly those that can lead to moisture penetration, must be rectified or can affect the finish quality.

Any existing crazed or flaking paint, dirt, grease or other surface contaminants should be removed.

For optimum performance apply to a substrate that has been primed with Wethertex ST1 Quick Dry Stabilising Primer.

Scaffolding must be independently tied to allow for uninterrupted application.



Application


Stir the product thoroughly and do not contaminate.

For application by hawk and trowel apply to 1-2mm thick and texture using a High Build application roller, or other texturing rollers or tools. For spray application, prime all areas to be decorated.

For best results in terms of finish, coverage, speed of application and low over spray the following set up is recommended:

Use a GC 200/24 2HP compressor or larger that can continuously deliver a maximum of 80psi at 4-5 cubic feet per minute on a 3 metre (max) length air-line to the spray gun. A GC 330 hopper feed spray gun with a 3mm air cap and tip size of 3-4mm. Apply at 40psi air flow/ spraying pressure with an 18” (450mm) distance from gun tip to the surface being coated.

Cover areas not to be sprayed with masking tape and wet strength masking paper or film. Spray using a ‘cross hatch’ method, i.e. horizontally & vertically to achieve a full, uniform and even texture overall. Clean the tip and air cap frequently during use to prevent blocking.

Apply all products in accordance with BS 6150: 2006 Code of Practice for painting of buildings and BS 8000: Part 12: 1989 Code of Practice for decorative wall coverings and painting.



Storage


When stored unopened in a dry place at temperatures above 5ºC, shelf life is 12 months from the date of manufacture.

If you have any leftover product, ensure that you close the tin by replacing the lid firmly and securely and store in a safe place.

Protect from frost.

To avoid the risk of spillage, always store and transport in a secure upright position.



Tool Cleaning


All equipment must be washed with clean, cold water immediately after use. Waste material should not be emptied in the drainage systems. Some local authorities have special facilities for the disposal of leftover paint. Please do not add any product into drains or watercourses.

Question: 

Hi, Can Wethertex HBS Flex-Coat Hi-Build Coating be used on a wall with K-rend on it. Thanks

Answer: 

Assuming the wall with K-Rend applied is clean, dry, sound and prepared as detailed in the Technical Data sheet,  is then primed with Wethertex ST1 Quick Dry Stabilising Primer, Wethertex HBS Flex-Coat Hi-Build Coating can be use.

questions howard on 2021-04-10 14:51:31
Question: 

I have new cement render done to front of bungalow (left a few months to fully cure). Some hairline cracks have appeared. Was about to buy a product called Bedec but only available in 5l. Will this so pretty much the same job? Does it dry glossy or matt.?

Answer: 

Assuming the render is clean, dry, sound and prepared as detailed in the Technical Data sheet we can recommend Wethertex HBS Flex-Coat Hi-Build Coating, this is in a matt finish.

This product can cover hairline cracks, any active cracks must be rectified prior to application and bare render should be primed first with Wethertex ST1 Quick Dry Stabilising Primer.

questions Wynne  on 2021-03-02 12:26:04
Question: 

I live in a 1936 built house which has a pebble dash exterior. The wall seems stable but has a few fine cracks and I was hoping to cover this with a breathable water proof coating. Would Wether HBS Flex-Coat Hi Build coating be suitable. ? Also can this be applied without having to use a brush ?

Answer: 

Wethertex HBS Flex-Coat is a highly breathable, waterproof, high build exterior coating. It can be applied with a textured roller or hawk and trowel to obtain your desired textured finish.

questions Richard on 2020-05-08 11:55:08
Question: 

Hi. I would like to ask if Wethertex HBS Flex-Coat Hi-Build Coating would be suitable for my property. I have and old brick built house which in places has no cavity wall. The building has been rendered using a lime based render. I need to do some repairs to the render and then repaint. I was hoping that a textured paint would assist in hiding the repared areas, but I am concerned that the final finish needs to be breathable so as not to cause problems. Is this product suitable in these circumstances? Thanks

Answer: 

This cannot be applied over a lime render. It will adhere initially but it will start to blister after a short period of time.

questions Lionel Owen on 2019-08-31 19:39:48
Question: 

I have old (flakey in places)highly textured, high build paint on concrete render that I need to remove in order to apply another coat of smoother high build properly. What is the best way and easiest to remove high build please? Many thanks

Answer: 

You could try something like Thermoguard Thermostrip PRO to soften the existing coating for removal but ultimately we would assume it necessary to employ pressure washing, scraping, wire brushing, etc. to gain complete removal.

questions Richard Measures on 2019-08-28 12:50:05
Question: 

I have bare breezeblock to cover on a garage - will this product do the job? I'm looking for a rough finish rather than smooth

Answer:

questions Peter Hilling on 2019-08-09 16:39:22
Question: 

I want to apply Wethertex to a hollow block retaining garden wall, but my concern is that damp could come through the wall from the back and damage the Wethertex. My question - Is there a waterproof coating that can be used on the wall on to which I can then paint the Wethertex

Answer: 

Depending on the level of negative water pressure expected, something like Sikalastic 1K, followed by applicaiton of Wethertex HBS Flex-Coat Hi-Build Coating.

Can you this product to paint over the outside walls (house)if they have been painted previously with waterproof paint . Thanks.

Answer: 

Wethertex HBS Flex-Coat Hi-Build Coating can be used over existing coatings however it does depend on which type has been applied. As we do not know this we would recommend a test area is applied to ascertain suitability and would advise the use of Wethertex ST1 Quick Dry Stabilising Primer also.

questions Nicholas on 2019-01-22 13:05:24
Question: 

Hi Is this paint, suitable for a garden wall surrounding our patio, which I’d made from blocks?

Answer: 

Wethertex HBS Flex-Coat Hi-Build Coating can be applied to blockwork, in this particular application the important factor would be to ensure no water/moisture is allowed to penetrate through the wall from behind the coating to cause issues.
