How do I apply silicone to concrete?

If you wanted to use an acid cure or a neutral cure silicone with concrete we recommend that you use a primer which is shown in our product data sheet. We recommend polyurethane in preference to Silicone.

Can Maxisil A Ceramic be painted?

No silicone should not be painted to maintain its flexibility. (We recommend if you need to fill gaps use an acrylic sealant that can be painted over like gap filler.)

Can it be used on metal?

Yes, it can be used on metals but not on bare or untreated metals.

Durability & guarantee – How long does it last?

Expansion joints are maintenance joints & built to absorb movements between different materials in the building sector, therefore, these should be checked frequently, Guarantee differs from each application so this cannot be generalised -Warrant only that it’s product meets their specifications

Can it be used for expansion joints on floors?

Yes, this is specially designed for this reason in domestic flooring.

Can Maxisil A Ceramic be used on the following: swimming pools – mirrors – in showers – on marble & stone?

Only to be used in bathroom, kitchen & sanitary areas. (See product data sheet for further info.) For swimming pool use Maxisil P, for mirrors use special silicone for mirrors, for Natural stone use Maxisil N.

Can I use Maxisil A Ceramic outside?

Yes, with its interior & exterior use, it has U.V resistance & excellent weatherablity.

Will Maxisil A Ceramic stop mould and fungi from appearing completely?

Our silicones have fungicides built in to resist mould appearance but once fungicides have expired mould will appear eventually & then the joint should be replaced. Regular cleaning & fresh air will extend the lifetime of the expansion joint. Through regulations, all silicone are only allowed to have a certain amount of fungicides built in therefore all products will face the same deterioration over a period of time.

Can you use Maxisil without your recommended clean up product (Smoothtex)?

Yes, you can use water & detergent to clean up any silicone but with this option, there is always a risk of discolouration. Smoothtex is designed for the following reasons:

  • It does not discolour the silicone
  • It does not attack your skin – especially for people that apply silicone frequently
  • It has the best cleaning properties for these products for a professional finish
  • (Use only Maxisil N Smoothtex especially for Natural Stone silicone)

How long will the silicone last after I have opened it?

We recommend after use leave nozzle attached on the tube, therefore the silicone will dry slowly in the actual nozzle itself, and replace with a new nozzle for further use. Store silicone in a cool place away from sunlight & heat. The shelf life is 12 months at room temperature?

Why is your silicone more expensive than common silicone products, has it secret ingredient?

Our products are not designed for the D.I.Y. market but more for professional users like tilers & silicone application tradesmen who depend on quality silicone to guarantee their work. As we are similar micro brewery where we focus on producing a product that is the best possible quality for the market. We can boast better quality and workability that is achieved on years of experience in the European Market, where we design these products, especially for professional users. Our silicones also come in a large colour range of colours.

How many lineal meters would I expect to cover from one tube of Maxisil?

On a 5mm joint normal depth, you can expect around 7 to 10 mtrs.

Is there a product to remove excess silicone that has been left to dry on tiles?

No. The best thing to do use is a paint scraper for flat surfaces like tiles or bath tubs. For old silicone, joints use a Stanley knife & clean up with acetone

Can I use maxisil to repair my gutters?

No. For gutters use a neutral cure silicone like roof & gutters from Selleys

How long after applying Maxisil can I use my shower?

24hrs or next day

Will solvent-based tile adhesives react with Maxisil A Ceramic?

In this particular case, we recommend doing your own testing because the compatibility depends on too many factors, such as:

  • The type of Solvent
  • Is the Adhesive fully dried out or relatively fresh?
  • The reaction between the softener from the Maxisil and the Adhesive

Why do I need to use an Applicator to apply Maxisil A Ceramic?

You don’t need to use an Applicator but what else are you going to use, your fingers like some people still do! The Applicator helps to make a perfect joint and is a tool to remove excess silicone, it makes a perfect finish without the use of masking tape which will save you time.
