Cemher Primer 100

|

Rated 4.5/5 by hundreds of happy customers

£25.00 (incl. VAT)

Size

Primer 100® is a water-based primer that acts as a bond promoter between surfaces and microcement. It stands out for its high adherence and for maintaining residual tack for 12 hours. It has a high elasticity which gives it excellent resistant to different weather conditions.

  • Bonds microcement to a wide range of surfaces
  • Suitable for absorbent and non-absorbent surfaces
  • High adherence, 12 hours residual tack

Uses / Areas of Application

Apply Primer 100 to the surface prior to the application of microcement to increase adhesion. This is an essential step in the majority of microcement applications.

Primer 100 is suitable for use on absorbent and non-absorbent surfaces.

Compatible surfaces include: plasterboard, plaster, painted walls, cement board, Aqua4ma panels, concrete, screed, self-leveller, mdf, OSB, plywood, tiles, marble, metal or terrazzo.

Primer 100 can be applied over polyurethane sealers should subsequent microcement coats be required.

It is advised to give non-absorbent a sand with a low grit sandpaper in advance to give them a key, prior to application of Primer 100.

Characteristics / Benefits

  • Adhesion promoter for absorbent and non-absorbent
  • Applicable by roller or brush in a single coat
  • Water based, non-flammable
  • The product is supplied ready for use
  • Solvent free
  • Zero VOC, environmentally friendly
  • Easy to apply
  • Compatible with a wide range of products

Before applying Primer 100® the substrate must be properly prepared. It must be dry, clean and free of dust, grease or dirt, with a moisture content of no more than 5%.

Primer 100® is a single component that is ready for use.

Once applied wait a minimum of 30 minutes before applying the first coat of microcement and no more than 12 hours.

It can be applied by spray, brush or roller, covering the surface well.

For highly absorbent surfaces like fresh plaster and freshly laid concrete, apply a diluted coat of Primer 100 (50% Water : 50% Primer 100), followed by a neat coat of Primer 100.

I’ve been using relentless microcement for quite a few years now, great product range. They have pretty much everything you need for your projects whether it be inside, outside, worktops, bathrooms, and flooring. Richie and sally are easy to talk to and they know everything you need to know about their products. 5 stars everytime

We’re over the moon

Amazing product and service as always from Relentless. Just finished my living room floor and walls and we’re over the moon with the finish. Thanks Relentless 👍

There’s a product for every need!

I’ve done quite a few jobs now over the past four years and can’t fault it. There’s a product for every need! It’s easy to apply once you get the hang of it and anything that you’re not sure about relentless are there to advise you. The only problem you’ll have is deciding which colour to choose !

Products are great

Products are great and we have purchased them several times, but the highlight is costumer servise. It’s rare to have prompt and professional costumer service – this is the main reason why we are choosing this company. We had issues once with the delivery and Sally handled it in the best way possible. Overall delivery is actually super quick.
