Are Rizistal paints suitable for domestic areas?

Rizistal products are low odour, solvent free, epoxy paints making them ideal for domestic areas, such as garages and workshops. One 5 kg unit of Rizistal EC220 should cover 20m2 over sealed concrete.

What colours are available?

Our standard colour range for paints and mortars include Light and Dark Grey, Black, Office Red, Grass Green, Golden Yellow, French and Bright Blue, Stone, and for repair mortars, Natural.

What tools are needed for applying the Rizistal paints and repair mortars?

An electric mixing paddle is required for both products. Paints should be applied with a 12-inch medium pile nylon roller, and mortars applied with a finishing trowel. All recommended tools are available in our shop.

When can I paint new concrete?

Concrete must be laid for at least 28 days before paints and mortars can be applied. If Rizistal TC210 Tack Coat is applied before application, concrete may be only 14 days old as it provides a damp-proof layer.

Can I paint over old paint?

Yes, you can, however, it is important that any loose paint is removed via mechanical means and the surface is prepared via sanding/grinding to give a good key to the new paint. In general, it is recommended to prepare back to the substrate and apply two coats.

Do any of your Epoxy Repair products give off any strong odours?

There is a slight smell to the repair products but only from short range during application; none of the products have been shown to taint.

Can your Epoxy Concrete Repair Mortar be used in wet or damp conditions?

Any standing or pooled water must be dried off before use; damp substrates can be prepared using our Epoxy Tack Coat Primer prior to application of the Repair Mortar to ensure maximum adhesion.

Can you tell me the approximate coverage for your Floor Paints?

Coverage for our Gloss Epoxy Floor Paint is approximately 5m2 per kilogram of floor paint. However, this can vary based on the porosity and quality of the substrate.

I have a garage workshop floor covered in oil to repair what products can I use?

Any free oil will have to be cleaned off with an appropriate degreaser or detergent such as Rizistalclean prior to application of any of our products. Previously oil-contaminated areas should be primed using Rizistal Epoxy Tack Coat Primer to ensure good adhesion to the contaminated substrate.

How many linear meters will 1 pack of Epiflex give me?

Each pack of Epiflex Jointing Mastic will achieve between 12 linear meters, based on a 10mm by 20mm joint.

Can your Epoxy Paints be applied to boards on a mezzanine floor?

Yes, all boards should, however, be primed using our Water Based Polyurethane Clear Floor Coating before applying the Gloss Epoxy Floor Paint.

Does the Rizistal Epoxy Asphalt & Tarmac Repair Mortar need heating up or can it be cold poured/applied?

The mortar doesn’t need heating up; however, we advise you try to keep the material around 10 – 15oC before use. It can be applied to substrates which are as low as 5 oC as long as the material is conditioned.

Can you tell me whether your Epoxy Repair Mortar will bond to metal?

Yes, the mortar will adhere to metal – however, it should be noted that the bond is not as strong as to concrete.

Is the acrylic roof treatment suitable for use on a flat felt roof subject to a little water ponding? Also, how long does the treatment last?

Yes, the acrylic roof treatment can be applied to a flat felt roof providing it is prepared to remove all loose dirt, standing water, moss etc. We advise that the coating lasts for roughly 5 years before you may need to re-apply. We recommend that the product is not applied to roofs with ponding water as this can affect performance during the lifetime of time product. However, if you can level the surface to remove the ponding the product would be fine to use.

Can the paints get too hot?

If paints are left in warm atmospheric conditions (> 18 oC), pot life and quality of the install can be affected. Warmer materials will begin to set quicker, therefore application must take place immediately after mixing in these instances.

Once the paint has been mixed it can start to smoke/overheat if not applied within the working time. This is caused by the exotherm of the chemical reaction. Note, the paint is no longer useable at this stage.

How long does a product take to cure?

You can find the curing times of all products in the technical data sheet located in the technical specifications, of each specific product.

What are the coverage rates of a product?

All coverage rates of each specific product can be found on their individual product pages to the right-hand side of the images.

When can I apply a second coat?

A second coat can be applied after an overnight cure of a first coat. A second coat will provide a better finish as well as improve the longevity of the product.

Do I need to use a primer for mortars?

We recommend using a primer to increase the strength of the mechanical bond however it is not essential. If applying to correctly prepared concrete (laitance removed) a primer is not necessary.

Can I split a single unit?

We do not recommend the splitting of packs due to the precise nature of the mix ratio. Paints and mortars need to be fully homogenised in terms of resins, fillers, and additives in order to achieve the desired finish.
