Primers and Additives

Our repairing primers and additives come courtesy of Remmers and Sika. There are bond promoters, rust inhibitors, binders, corrosion protection, salt inhibitors, strengtheners, modifiers, special fillers and quartz! All intended to strengthen and reinforce the attributes of your systems. If you have a project that needs a specific requirement in abundance, then an additive can assure you that. 

When choosing a primer, be sure to check the Product Data Sheet of both the primer and the system you plan to use after. Most products are very specific about which primer should be used in conjunction and the wrong choice of primer can result in chemicals being mixed that are not best suited. Usually a manufacturer will suggest their own primer, but this is with good reason as the two will have been designed with each other in mind. 

If you are unsure at all which product would suit your needs best, please give our Technical Support Team a call on 0113 245 5450, email us on [email protected] or get in touch on one of our social media outlets where our web team will help as best as they can.
